ESP8266 WiFi gateway port for MySensors

[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?

@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:

ESP8266 MySensors Gateway
Connecting to layla
......Connected!
IP: 192.168.0.102
0;0;3;0;9;gateway started, id=0, parent=0, distance=0

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)
0;0;3;0;9;Radio init failed. Check wiring.

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?
