ESP8266 WiFi gateway port for MySensors

[Pseudomizer]

The only changes to the sketch are the SSID, the pass and the debug line

Serial.setDebugOutput(true);

as instructed. No other changes were made.

Here the the debug output....you will see multiple resets in a row based on the internal watchdog timer.

Triple-check your radio wiring.

[Yveaux]

@hek said:

Triple-check your radio wiring.

Or try with a different radio. The crash seems to happen in the radio init part.

[Pseudomizer]

I just replaced the NRF with a new NRF and then again as I have 4 total. With every single one the same error.

The wiring matches exactly the picture from mysensors.

This is driving me crazy...

[miguelingles]

Hi, I tried the bridge with a rfm69hw module. It starts all well but does not receive any information. Neither shows startup information module .
Where to put the DIO0 . I tried on several pins ( changing IRQ number) but no thoughts about doing anything.

[Yveaux]

@miguelingles I didn't test with a rfm69hw module and I'm not aware of anybody else testing with this setup.
Probably you have to test step by step what work and what not.
Start with the radio initialization to see if the communication is ok, and go on from there.

[Yveaux]

@Pseudomizer past few days @hek and I have been working on better diagnosis for the ESP8266 regarding radio communication failures.
Please try if the version of MySensors development helps in diagnosing your problems.
Make sure to uncomment the line

//#define MY_DEBUG_VERBOSE

in MyConfig.h and make the same changes to ssid & password as you did before.
This version will dump diagnostics of NRF communications and a full register dump when starting up.
Good luck!

[Pseudomizer]

Thanks a lot. This version provides much more details but at this stage of my learning progress I am not able to understand all those registers where I have to rely on your help guys. I assume that my password is not being exposed here.

@Pseudomizer just had a quick look at your results. Radio config (and this communication) seem to be OK, but it restarts due to watchdog timeout.
Hopefully tonight I can have a better look.

[miguelingles]

when I put the development package I can not compile anything (all gives me error). I tried it with a clean install and nothing.
I think the problem is the IRQ pin DIØØ , if the ESP cpu does not recognize this interruption when the RF module receives data is unable to apply for the request .

[Yveaux]

@miguelingles said:

The irq pin from the nrf24 stays unconnected, like the build instructions clearly state!

[miguelingles]

but RF69 need irq.

[Yveaux]

@miguelingles didn't know you were talking about rf69... Sorry but I cannot keep track of what everyone is using.

[Yveaux]

For everyone wondering what serial output during startup of the ESP8266-NRF24 gateway should look like (all captures taken using link development branch from Oct 6, 2015 (hek just merged gateway-refactoring this morning, so output might have slightly changed)) .

WiFi startup comes first after reset, followed by MySensors (nRF24) startup:

@Pseudomizer Had a better look at your crashdump.
Your ESP seems to crash with a watchdog timeout when MySensors is setting the datarate (or shortly after that) after nRF24 has been initialized.
Default datarate is RF24_250KBPS.

Some questions, trying to rule things out:

• Do you use this default datarate?
• Could it be that you have an nRF24L01+ clone, which in reality is a nRF24L01 (clone)?
• Did you ever try and succeed to connect these radios to a regular Arduino?
• Are all radio's from the same batch/order?

[Pseudomizer]

I tried multiple different data rates when I created the ethernet gateway from mysensors. It didn't work at all in terms of connecting the sensors to the gateway while the gateway was visible in Vera until I made them all the same data rate. If I recall correctly I got them working with both at 250kpbs or 1Mbps.

Since I tried to build the wifi gateway I haven't checked the data rates. I am going to check this next.

In regards to your other questions:
I purchased 4 radios from Amazon:
http://www.amazon.com/nRF24L01-Wireless-Transceiver-Arduino-Compatible/dp/B00E594ZX0/ref=cm_cr_pr_product_top?ie=UTF8

Yes, those radios work totally fine with the ethernet gateway from mysensors and I had two sensors attached. My goal is to have a wireless gateway so I can place it anywhere in the house and your great work would enable me to do so.

[Pseudomizer]

Thinking about the data rate... at the moment I don't have any other sensors powered on at all which means I am just installing the wifi gateway. There should be no mismatch in the data rates unless I would have at least one sensor with a different data rate causing the issue. The Wifi gateway should boot up successfully without any client sensor.

Is my thinking correct?

[miguelingles]

@Yveaux said:

y but I

it,s works !!!!! you have to do is remove the DIO0 while Bots and put it quickly . If not removed DIO0 not start.

[Pseudomizer]

I have done EXTENSIVE testing and I got it working now but I don't understand why.

It seems like my MyConfig.h is broken which is the one which I copied over from your development package. I used one of my MyConfig.h files and the module boot was successfull and it did not crash anymore. It is stable and fully integrated into Vera with sensors now.

I also tested the different data rates. I tested 250KBPS and 1MBPS and both work fine as long as I configure the gateway and the sensor clients with the same data rate. If I use different data rates between client and gateway, the gateway does NOT crash but the sensor clients simply don't connect.

Now I have a working MyConfig.h and a broken MyConfig.h. Here is the WORKING MyConfig.h file.

I don't understand why the second one makes the module reboot constantly. However, I am happy now that it is working but I wanted to share my experience and maybe it can help others to troubleshoot this and understand why this was happening as I am sure I will not be the only one having that issue in the future.

I do appreciate all the help so far and I wouldn't have been able to solve it without your help Yveaux. THANK YOU!!!

You cannot mix MyConfig.h between branches.

In the development brach all MySensors related defines has the prefix "MY_".

Hi, if it possible to show a sketch with an ESP8266 WIFI => MQTT gateway? I figure out, that the received sensor data will automatic publish to my MQTT Server running on my Raspi. Then i can install this pice of wonderfull work in every room from my house

[hek]

I created a simple ESP-MQTT sketch a while ago. I've only done some simple tests using it. Feedback appreciated.

Testing the above sket from the development branch with a new sensbender micro I get:
mygateway/255/255/3/0/3 (null) on MQTT

This is an id request. I answer this request with
mosquitto_pub -h ds -t "mygateway/255/255/3/0/4" -m 8
which should set the ID 8 on the sensbender micro in my undestanding. I can see the message in the serial terminal on the ESP-8266 but the message doesn't arrive at the sensbender micro.

Is my message to set the id correct?

[hek]

Yes, the response message looks ok. But I must confess that I haven't verified the MQTT gateway much yet. Probably something I've missed (=bug).

Do you have the possibility to to see where the message ends up or being thrown away (debug-print-debugging is awesome, yes I know...) in the MQTT gateway?

Or wait a few days until I've had time to look at it.

[FotoFieber]

There seems to be a bug in incomingMQTT:
replace
for (str = strtok_r(topic, "/", &p); str && i < 5;
with
for (str = strtok_r(topic, "/", &p); str && i <= 5;

or it will never send a message.

There seems to be another problem:
0;0;3;0;9;send: 0-0-0-255 s=255,c=3,t=4,pt=0,l=1,sg=0,st=fail:8

Why is the payload in st=fail?

The messages sent to MQTT seem to make a merry go round and come back....

[hek]

@FotoFieber said:

The payload (8) seems correct. Gateway just never received any ack from node... which is fine for broadcast messages (to node 255) such as this.

The messages sent to MQTT seem to make a merry go round and come back....

Ok, like you suspected earlier? So we need to subscribe to something else than we publish to then...

[FotoFieber]

@hek
Loaded the ethernet ESP-8266 gateway and entered with telnet:
255;255;3;0;4;8

It is working as it should. Now I have assigned the id 8.

Tried to solve the merry go round but it didn't help. Now I let the stage to the pros..

[Fabien]

Do you think we can use this board with MySensors (with NRF24 or RFM69) ?

[Mike Cayouette]

Hi,

If I want to use the GatewayESP8266MQTTClient sketch located in the development branch do I also need to use the mysensors libraries in that branch?

Thank you,

Mike

[hek]

@Mike-Cayouette

Yes

[vickey]

@hek Thanks for the code. I have few questions in my mind. Firstly do I just have to upload this ESP8266MQTTClient.ino sketch on esp8266 12-E model? or does it needs anything to add in the sketch except SSID and password? I want to use ESP-8266-E and NRF24L01+ as gateway for openhab. If it is possible then, do I have to adopt the same procedure for configuring openhab as ethernet gateway? Secondly, Can I make two gateways using this sketch, is this possible? As I want to add sensors which are 500 meters away at my farmhouse.

[joshmosh]

This is a bit off topic, but hopefully not too off
What about a port of the MySensors library /API to ESP8266 ? Instead of two "boards" (Arduino nano plus nRF24L01+) only one would be required. For simple sensors an ESP-01 would be sufficient - about the size of a nRF24, but with much more muscle than an Arduino. Of course, running off a battery probably would not work because of the high power consumption of the ESP.

Or am I asking for something which is already possible ?

Entering SSID/PW should be enough.

I'm not an expert on openhab.. so I'll let someone else answer this one. But the ESP variant behaves exactly like the W5100 version.

Secondly, Can I make two gateways using this sketch, is this possible? As I want to add sensors which are 500 meters away at my farmhouse.

If openhab supports multiple gateways, sure. But you might wanna run sensor networks on different frequencies or changing MY_RF24_BASE_RADIO_ID.

@joshmosh

Or am I asking for something which is already possible ?

Yes, the code runs directly on the ESP8266.

that's good news, thank you ! Now the most expensive part will be the power supply

[joshmosh]

@hek
Good morning. I had wired up my nodemcu a nRF24L01+, loaded the gateway sketch and bingo ! Zero problems, works like charm. Thanks a lot !!!

I am using Domoticz as controller, with a serial USB gateway to connect my various sensors. In the serial console of the ESP8266 gateway I see that the messages of my sensors show up, but since I have not yet announced the gateway to Domoticz, there seems to be no interference. If I connect the ESP8266 gateway to a controller (in my case Domoticz), I guess that it will be required that the nodes need to choose the respective gateway (by using the parentNodeId) with which they like to communicate ? Currently, I am using parentNodeId = AUTO in all my nodes.
I will do some testing to get an idea of the reach of my WiFi compared to the reach of my serial USB gateway (I have a nRF24L01+ with external antanna and booster in my gateway, so I am able to "see" a portable node even outside my house and 50 m away.

Again, thank you for this very useful extension of MySensors. I think I have not yet an estimate of the full potential of it

Cheers

Hello,

I also tried to build a WiFi gateway today.
I get the following serial output when starting the gateway:

ESP8266 MySensors Gateway
Connecting to *************
...Connected!
IP: 192.168.1.218
0;0;3;0;9;gateway started, id=0, parent=0, distance=0

Does this mean that everything is correct and I can integrate it into my FHEM solution?
Currently I'm working with a serial gatway. Do I have to modify something in my sensors when I switch to the new gateway?

[Yveaux]

@gloob said:

Looking good! Congrats!

I have no experience using FHEM, but you should be able to use the WiFi gateway just like the regular ethernet gateway (as seen from FHEM).
So look around on this forum for any posts regarding usage of FHEM & ethernet gateway and you should be good.

[Yveaux]

@joshmosh You cannot have multiple gateways in a single MySensors network. The node-ID of the gateway is always hardcoded to 0.
If you want to run multiple networks, each should have a unique RF24_CHANNEL & RF24_BASE_RADIO_ID combination. For best results make sure to have a separate RF24_CHANNEL for each network, and don't use directly adjacent channels.

[FotoFieber]

Playing with AES signing and encryption I enabled verbose debug.

#define MY_DEBUG_VERBOSE

The sketch crashes with this setting but seems to work fine without verbose debug.

Is this a problem of my setup or a problem in the code?

@FotoFieber said:

I'll opt for the first, but lets see:

• What ESP hardware are you using?
• Which Arduino/ESP8266 port/MySensors version are you using?
• Did you define both DEBUG and MY_DEBUG_VERBOSE?
• What did you do to 'Play with AES signing and encryption' ?
• AES stuff is untested for ESP8266, however, you don't seen to get that far as it crashes during startup.
• My startup log (see here ) shows what it shoes during startup with DEBUG and MY_DEBUG_VERBOSE enabled.

[FotoFieber]

@Yveaux

• ESP12E
• Development Version
• Defined both DEBUG AND VERBOSE
• Playing with AES:

#define MY_RF24_CHANNEL  13
#define MY_RF24_BASE_RADIO_ID ((uint64_t)0xF8A813FC09CL)

#define MY_RF24_ENABLE_ENCRYPTION
#define MY_RF24_ENCRYPTKEY  secret....

#define MY_SIGNING_SOFT // Software signing enabled

#define MY_SIGNING_SOFT_SERIAL secret....
// Key to use for HMAC calculation in soft signing (32 bytes)

#define MY_SIGNING_SOFT_HMAC_KEY secret

It seems to work perfect without the verbose debug.

I will test now without AES. My gut tells me, I should look inside the AES stuff.

@Yveaux
Thank you for this piece of information - I was not aware of this fact.
My idea was to reduce cost and parts count for sensors by using ESPs instead of nRF plus Arduino. Since I have Domoticz as controller, there is pehaps no need for an additional gateway, because Domoticz can handle TCP-attached sensors. Of course this would require to use WiFi instead of nRF24 as underlying transport for MySensors. My interpretation of some of hek's contributions is that he is working on it for realisation in version 1.6.

[FotoFieber]

@Yveaux
Downloaded the development branch again and used the sketch included as example. The sketch is hanging too. My gut was wrong, AES is not the problem.

[vickey]

Hi.
I am having an issue with my ESP8266 gateway. I have tried all versions of mysensors including developmental versions, but my esp8266 does not show any serial debug, nor it gets connected to my router. I also enabled debug in configuration file. When I install AT firmware, it replies to AT command, it also works with nodemcu firmware, but it does not respond with Arduino firmware. May someone help me?

[Anduril]

Finally I got my NodeMCU and tried the WiFi gateway too. But I get the following messages (with Serial.setDebugOutput(true);):

Additionally I tried to use

  IPAddress ip(192, 168, 38, 18);  /* Set to whatever IP address you'd like the gateway to have */
  WiFi.config(ip);

to avoid DHCP, but that gives error during compiling:

no matching function for call to 'ESP8266WiFiClass::config(IPAddress&)'

Any hints how to solve?

Thanks

Edit:
to find the problem I tested to connect the ESP to the wifi-hotspot of my smartphone... worked. Is it maybe a problem if the password contain special characters which behave strange during compiling?

[Yveaux]

@Anduril said:

no WLAN found, reconnect after 1s

That's a clear indication the ESP cannot connect to your WiFi accesspoint.
Is the SSID matching your accesspoint ('WLAN')?
Is the encryption supported by the ESP (see e.g. https://nurdspace.nl/ESP8266#Features -- not sure if it is accurate)
Weird characters in the password could be problematic (and of course the password is case-sensitive).

Changing between DHCP/Fixed IP won't make a difference here, as the ESP doesn't even connect. IP configuration starts once connected.

[Anduril]

@Yveaux
SSID is 'WLAN' (all capital). Encryption is WPA2 which should be supported. The password contains '|' (don't know the name, vertical line) and 'ß' (german character). I use them among other more common ones to raise the complexity of the encryption. As I am using a bunch of wifi devices I don't want to go around and change passwords for all if not absolutely necessary. Is there a way to specify these 'weird characters' e.g. by ASCII codes or anything else?

Changing the IP was not to solve this problem but for future use, as my DHCP is not very good. Can you tell me how to fix IP else?

[Yveaux]

@Anduril try to print your password to the serial console and see if it matches the password you entered in the sketch.

[Anduril]

good idea @Yveaux, seems that 'ß' is the problem. serial.print shows ß at that position. Do you know how to avoid that?

[Yveaux]

@Anduril probably Unicode problem of the editor. I assume you use the Arduino editor? Try a simple editor like notepad to type the problematic character, or directly type it in windows by setting your keyboard in numpad mode and type it's ascii code: alt+225

[Anduril]

@Yveaux tried with a nano to print out "ß" to serial, no problems. After that I tried that sketch on ESP:

void setup() {
  Serial.begin(115200);
  const char *pass = "ß1ß";
  Serial.println(" "); //to break line after rubbish at init
  Serial.println(pass);
}

[not readable/copyable stuff]
ß1ß

So in general it should be no problem compiling the char 'ß' even on ESP.. Also in the ESPGateway sketch I don't see anything that is changing the *pass, but maybe you know what is going on with this string in more detail.

edit: it seems to happen even before void setup in the gw sketch. I uncommented everything in setup, loop and output, but still get the distorted serial print of pass.

[Yveaux]

@Anduril I guess it shouldn't make a difference. What happens if you copy/paste the "ß1ß" string from your test sketch into the ESP gateway sketch as password and print that to serial? (make sure to use the same editor on both sketches)

[Anduril]

@Yveaux already tried that. When using my own sketch I get "ß1ß", when using the gw sketch (with really everything commented out, so no functionality) I get "ß1ß". I thought that it might be a problem of UFT encoding, had this issue with transfering LaTeX files created on linux system to windows system and vice versa: the system that creates the file sets the charset.
But I also created a completely new .ino with the gateway-code inside and new created gatewayutil.h with data copied in notepad++, but no succes.
And yes I use Arduino IDE as editor. Is there a good way to use another editor and compile/upload without the IDE?

[Yveaux]

@Anduril I'm still convinced it has something to do with Unicode, but very hard to nail from a distance without the actual files...
Maybe @hek has seen this before?

[hek]

Nope, not the slightest idea.

@Anduril
Couldn't you just temporarily change password on router to rule out other stuff?

[Anduril]

@hek yeah already did this, when leaving out ß it works perfect. So no problem with router or ESP hardware. But changing the wifi password would be the worst case, as I have to reassign that to squeezeboxes, smartphones, laptops, wifi printer,... (and all guest devices of friends/familie) but still possible if all other things fail.
@Yveaux Would it help if I send you the files for verification? Is it possible inside this forum or only via email?

[Anduril]

@Yveaux thank you very much for offering help with verification, but something strange happened during preperation of files: I took an example sketch and modified it to print the "ß1ß" on serial --> working fine.
But after saving the file I tried again, only reading rubbish. Thats strange! So it has something to do with saving the file and maybe setting a special encoding. Maybe thats related to the editor? Could you please try to redo what I explained and see if you get the same results? Thank you. @hek have you ever had such a problem of a sketch behaving differently after saving?

[Yveaux]

@Anduril Ok, did some tests:

Copied your problematic example string from this topic into Arduino IDE (1.6.5), on Windows 10:

Saved the sketch.

Viewed sketch.ino in notepad:

Newlines are f*cked up, but "ß1ß" can clearly be recognized.

Viewed the same sketch in HxD hex viewer:

And there we are! The string is stored as Unicode characters!

Reading it back in Arduino IDE:

Everything looks fine again.

Apparently the unicode string gets compiled directly and shows as multiple, wrong characters in your sketch when used/printed...

Ok, one more idea: you can try to store the ß character as an escaped ASCII character in you string (refer to this ).
This will look strange in the code, but should print correctly to the console:

The ASCII escape sequence for ß is \xE1
Your test sequence "ß1ß" then becomes "\xE11\xE1"

Please try this...

[Yveaux]

@mkeyno did you change anything to the gateway code, and which version of MySensors are you running?
I've ported the gateway code to ESP8266. That doesn't mean any sensor code will also automatically run on an ESP.
Packaged with MySensors are a lot of libraries that will not compile on ESP, so if you try to use one (pinchange int or timers) it will likely fail to compile.

[Anduril]

@Yveaux SUCCES!!! Thank you very much, your way worked nearly perfect. ONly small change: "ß" is represented by hexcode DF, so using \eDF gives the correct wifi password for me.
Now a last thing as bonus: how to setup a fixed ip and not using dhcp? My dhcp is not very usable as it reassigns all IPs on reboot (stupid firmware by Deutsche Telekom).

[Yveaux]

@Anduril Great to hear you got it to work!

how to setup a fixed ip and not using dhcp?

Google'd a bit. Seems like Wifi.config requires 3 parameters:

    // static ip, gateway, netmask
    WiFi.config(IPAddress(192,168,1,100), IPAddress(192,168,1,1), IPAddress(255,255,255,0));

Make sure to call it after WiFi.begin().

Btw. ESP8266 Arduino port follows the Arduino WiFi library API.

[hek]

You can set static ip in the dev-branch.

[Yveaux]

@hek said:

[mkeyno]

@Yveaux no buddy I used the last update of your repository, my question is , are you aware that your esp8266 sample sketch call library that wont work with esp architecture? I've compare last update with previous library and I've find the for couple of header file following code has been added
#ifdef AVR
#include <avr/interrupt.h>
#else
#error MsTimer2 library only works on AVR architecture
#endif

and I was wondering why your sample sketch call such file into the compiling

I'm using a NodeMCU with a NRF ( both from ebay),
Using the Regular library, and default sketch with SSID/pass updated.

i tried checking the error "rst cause:4, boot mode:(3,7)" but wasn't able to find something.

I even tried to power it using a USB cellphone charger, but i was unable to telnet so that rules out the power issue

Thanks in advance

[D_dude]

update,
the error changed to "rst cause:4, boot mode:(3,6)" once i added a capacitor.

These ESP's seem to walk in mysterious ways...
A lot of people have them, running without any issues (including myself and hek) and some people can't seem to get them to run stable.
On the net, a lot of stability/reset issues are are claimed to have a relation to power supply.

I even tried to power it using a USB cellphone charger, but i was unable to telnet so that rules out the power issue

There are a lot of assumptions in this sentence
What current rating is the cellphone charger? I'd advise one with at least 1amps, and a stable output.
Not being able to telnet to the gateway can have more issues then just the ESP crashing...

[D_dude]

@Yveaux
Thank you for the response.

As for the cell phone charger, I'm using a tablet charger Specifically original HP stream 7 charger, and it is able to provide more that 1amp. I Will try to use other charger/power supply to see if that helps.

PS: I reloaded the gateway sketch and the error went back to boot mode (3,7) even with cap present.

[Yveaux]

@D_dude I searched the net for a description of reset causes and boot modes but failed to find one.
I have no clue of what they mean.

[D_dude]

@Yveaux
thank you for your assistance. I will try adding some debug in the code on the weekend to see what exactly is not running and possibly causing crash.

[mfalkvidd]

I got a suggestion here to erase the flash before flashing. Haven't tried it yet, but it might help you @D_dude

[D_dude]

@mfalkvidd
Thank you, i will try this and post results.

[D_dude]

@mfalkvidd
tried erasing the flash using the method suggested but doesn't seem to be working for me. same result.
Thanks for the tip though.

[mfalkvidd]

Too bad. Thanks for posting your results.

[luisgcu]

here is my ESP8266 wifi gateway installed in wifi repeater box, taking the advantage that its has a 5 volts power supply.

[Yveaux]

@luisgcu Nice housing!
Thanks for the pics!

I'd been using the ESP gateway for several weeks, but recently was having trouble adding a new sensor I am developing.

Since the copy of dev I built it with was now out of date, I went ahead and updated... still wasn't working right so while I had the serial link to it I checked and noticed it was crashing and cycling. It would work for hours, until I fired up my new node, then crash about immediately. A few dozen debug(PSTR())'s later, I found a cause.

In core/MySensorsCore.cpp the result of _msg.getConfig() is dereferenced in a comparison, and it's possible it could return NULL ( like when it's a new node ). I put a check around that and it's not crashing anymore. Which is more than what I can say for my new sensor node....

I have not tested this change with an AVR.

I submitted PR 264.

[mfalkvidd]

Great work @soward !

[D_dude]

on some basic debugging, seems like my sketch is crashing in setupGateway.

infact even adding a print statement, it only prints first 3 chars.

My question is setupGateway takes output as an arg, which in turn is a function, should there be some parameters for this function?
also "Serial.print(serialBuffer);" does not print anything i added prints above and before and they don't show up either.

  va_end (args);
  Serial.print("A1");
  Serial.print(serialBuffer);
  Serial.print("A2");

any suggestions?

[Yveaux]

@D_dude flush the serial output after each print.
The ESP will output the serial data in the background while your programm continues and then it crashes.

Hi,
I'm getting all the time this:

Then it got stuck so I do reset and getting this in loop:

Means there's something wrong with your nRF communication. The WDT reset following this is normal.

i have been using wifi gateway with Domoticz controller without any problems until recentely. After the last update to beta version of the controller, the gateway crashes when the controller request gateway version:
Gateway startup complete.
Client 0: 0;0;3;0;2;

Exception (28):
epc1=0x4000bf80 epc2=0x00000000 epc3=0x00000000 excvaddr=0x00000000 depc=0x00000000

ctx: cont
sp: 3ffebf60 end: 3ffec1f0 offset: 01a0

I have tested with telnet client with the same request and it was ok. Then I saw that the request from controller was terminated with only <LF> and not with <CR><LF> and this is why it crashed. I have added the following to the sketch:

•    if (inChar == '\n')
    {  
      if (inputString[i].string[inputString[i].idx-1] != '\r') { // if the last char is not CR then add it
      inputString[i].string[inputString[i].idx++]='\r';
     }
      // a command was issued by the client
      // we will now try to send it to the actuator
  

and now it seems to work.
Is this the right way to go?
Thanks

@ciprian

Are you talking abut this line of code?
https://github.com/mysensors/Arduino/blob/development/libraries/MySensors/core/MyGatewayTransportEthernet.cpp#L194

[ciprian]

@hek My code is from GatewayESP8266.ino example in Mysensors 1.5, line 234.

[hek]

Ok! Mis-read this line---

After the last update to beta version....

Thought you were talking about the development branch. Sorry.

[Yht]

Hi all,
First, I have to say this is awsome what @Yveaux did, thank you!

Sorry if this question takes you back in time. I don't know what channel and id to use for the nodes,I tried channel 97 and id from 1-5 but it is not working..
are you using mesh lib?

[Yveaux]

@Yht said:

I don't know what channel and id to use for the nodes

Just leave the default channel untouched for both sensors and gateway. It should be fine.
The gateway will automatically be assigned ID 0, the nodes can have any fixed ID.
Dynamic ID assignment requires some extra software, as the gateway does not support it.

I'm also seeing my ESP8266 gateway crash when the controller requests its version.

I had not seen this thread so I started a new topic here: http://forum.mysensors.org/topic/2493/esp8266-wifi-gateway-crashes-and-reboots-when-controller-connects

hi,

maybe you have already seen it...but you can get cheap and smaller nodemcu. crazy price! I have ordered some, and waiting for them...

@scalz Nice! Thanks for the link!

[drock1985]

Just wanted to chime in and say thank you for this gateway script @Yveaux

I originally had an ethernet gateway for the longest time. But when I changed over to an OnHub router, it stopped working because it doesn't like to handle static IP, and the current branch sketch is too large to enable DHCP. This worked wonderfully with the OnHub out of the box (ver 7390.62.2) and shows up with a hostname of ESP_DA7D8B.

Thanks again!

Hi,
When testing the ESP8266MQTTClient (downloaded latest version of the library today) and compiled with the NodeMCU 1.0 ...... option I get an odd result. The message at startup is (please disregard the "Radio init fail" - the radio was not yet connected. I just wanted to check the WiFi

2dO,4`lLMØl 8ðÿ0;0;3;0;9;Starting gateway (RNNGE-, 1.6.0-beta)

connected with XXXyyy, channel 1
dhcp client start...
ip:192.168.1.167,mask:255.255.255.0,gw:192.168.1.1

I can see from the router that the connection to 192.168.1.167 is successful but the oddity is that I have set the gateway to use a static address and also connect to a SSID which is not XXXyyy. The defines are:

// Enable MY_IP_ADDRESS here if you want a static ip address (no DHCP)
#define MY_IP_ADDRESS 192,168,1,22
// If using static ip you need to define Gateway and Subnet address as well
#define MY_IP_GATEWAY_ADDRESS 192,168,1,1
#define MY_IP_SUBNET_ADDRESS 255,255,255,0

So the ESP8266 uses dhcp when it should have a static address and connects to a SSID which is not given but may have been previously used at earlier tests.

I have looked at the code and tried a few changes to defines but none resulted in the override of dhcp.
Anyone have a clue?

I have the exact hardware in this setup but can't even get to the point where the hardware is a problem! I'm having compile errors during verify that make no sense and that I can't seem to find in the forums using search:

In file included from Esp8266Gateway.ino:69:0:
C:\Users\xxxxx\Documents\Arduino\libraries\SPI/SPI.h:982:8: error: 'SPIClass' does not name a type
extern SPIClass SPI;

Any suggestions? I'm running windows 10 and Arduino 1.6.5 with the most current esp8266 board files through board manager.

Apparently me and anything arduino related are like oil and water, yet I keep buying the stuff.

I tried this on my laptop and it worked fine (the compile verify did anyway) so I'll be reinstalling the IDE and trying again and hopefully that resolves my issues!

[tjay4x4]

Yesterday I have successfully installed the ESP8266 module and it works fine, but the Vera3 show something strange now.

Has anyone experienced this?

[Yveaux]

@tjay4x4 Seems like to be an issue again when going from 8-bit to 32-bit architecture.
Can you connect the ESP to your PC and capture the serial output when connecting to your lights and controlling them?
