I'll try this as soon as possible. Although the ip network connection doesn't seem to be the issue since ip dedication is without problem.

What I have to mention: The setting was running great as a Serial Gateway config. But when I changed to ethernet gateway I was not able to restore this condition together with the W5100 shield. Moreover I don't know if the pin4 is making some trouble. As far as I know its used for writing to the sd card (which I don't use...).

This is what is coming out of the gateway debug:

Wow cool, so the hardware is basically running, but for some reason, the gateway doesn't accept the message.
I'll double-check the signing algorithm (perhaps I comment it to see, if there are arriving unsigned messages) and I will post the result.
Strange thing. Thank you very much!
I'll do this tonight.

Hi, I've cut present, setup and loop not to waist to much space. I edit and add them too...
Unfortunately as you can see, the gateway is not receiving anything and therefore not answering the node.
I will test with different hardware now, if there is something weird.

Hi,

I have trouble with my ethernet shield.
I tried different methods and there where different publications on how to connect, but in the end I was not able to get it running.
I tried: CE and CS pin on 6 and 5 with and without changing MISO/MOSI/SCK to A0 to A2, but the best result I got was an error free start of the gateway but not receiving any data from nodes so far (connection to ip network seems to be fine, at least the ip is declared via dhcp). The same setting was doing great without ethernet shield. Tried it also on a Mega but without success...
To sort out the power issue I put an extra 3.3 power regulator together with a big 470 microF capacitor which should do the trick.
Any ideas? I will post the exact wirings in a few minutes.

If you have one working in this setting, can you send me the exact sketch together with the wiring information?

Thank you!

Hi,
I was wondering if I could use the node red flows to attach mysensors to loxone. But I failed already in the first step: I don't get the my sensors software imported in node red.
Although I find the "Import" option in the UI, there is only little space and no specific name under library to depict what to import. So the left options are only clipboard and examples.
Could one of you experienced guys give me short push where i have to copy the files of the node-red-contrib-mysensors-master folder?
Thank you so much kd

thank you for the important hint.
Unfortunately it didn't solve the failure message. For my understanding the altsoftserial shouldn't be called since MY_RS485_ESPSERIAL is defined.

My code looks like this:

// Define this to enables DE-pin management on defined pin

SoftwareSerial swESP(14, 12, false, 256); 
#define MY_RS485_ESPSERIAL swESP

Hi,
I am just wondering, if it would be possible to use the esp8266 chip for wired projects with RS485. My intention is to use the form factor as well as power and mem space for small projects. Furthermore it would be possible to start the ESP with wlan connection for possible OTA update.
Because of the different softwareSerials tried to include the settings for ESP, but was not successful.
Please have a look. Do you see any problem in the following sketch files?

1. MyTransportRS485.cpp:

#if defined(MY_RS485_SWSERIAL)
SoftwareSerial& _dev = MY_RS485_SWSERIAL;
#elif defined(MY_RS485_ESPSERIAL)
SoftwareSerialESP& _dev = MY_RS485_ESPSERIAL;
#elif defined(__linux__)
SerialPort _dev = SerialPort(MY_RS485_HWSERIAL);
#elif defined(MY_RS485_HWSERIAL)
HardwareSerial& _dev = MY_RS485_HWSERIAL;
#else
AltSoftSerial _dev;
#endif

2. MotionSensorESP sample:

// ESP Software Serial
#include <SoftwareSerialESP.h>

// Enable debug prints to serial monitor
#define MY_DEBUG

// Enable RS485 transport layer
#define MY_RS485

// Define this to enables DE-pin management on defined pin
#define MY_RS485_DE_PIN 2

// Set RS485 baud rate to use
#define MY_RS485_BAUD_RATE 9600

// Enable this if RS485 is connected to a hardware serial port
//#define MY_RS485_HWSERIAL Serial1
//#define MY_RS485_ESPSERIAL
#include <MySensors.h>
SoftwareSerial swESP(14, 12, false, 256); 
#define MY_RS485_ESPSERIAL swESP

Now what is the output? The serial monitor tells me:

In file included from /Documents/Arduino/libraries/MySensors-development/drivers/AltSoftSerial/AltSoftSerial.cpp:32:0,
                 from /Documents/Arduino/libraries/MySensors-development/MySensors.h:309,
                 from /Documents/Arduino/MotionSensorESP_RS485/MotionSensorESP_RS485.ino:74:

 #error "Please define your board timer and pins"
  ^
exit status 1

Unfortunately I dont know where the AltSoftSerial is chosen. It is not included because of my definitions (as you can see above). So if it is not used, why I need to define boards? Any idea?
Thanks for your help!

Hi,
after getting the prototypes working (I dont know why but the ready to use bricks of max485 are not working, the bare ones do) I like to attach the gateway via ethernet to my controller. I am using the Arduino Ethernet Shield v1 from HanRun HR911105A 16/02.
Unfortunately I dont get any ethernet connection.
This is how I modified my code. Any ideas what went wrong?

Appreciate any suggestions...

Hi PJR,
now it is working with this code in the MyTransportRS485 without any changes on MySensors.h:

#if defined(MY_RS485_SWSERIAL)
SoftwareSerial& _dev = MY_RS485_SWSERIAL;
#elif defined(__linux__)
SerialPort _dev = SerialPort(MY_RS485_HWSERIAL);
#elif defined(MY_RS485_HWSERIAL)
HardwareSerial& _dev = MY_RS485_HWSERIAL;
#else
AltSoftSerial _dev;
#endif

As far as I can interpret the peace of code, the
#include "hal/transport/MyTransportRS485.cpp"
is active as soon as the MY_RS485 layer is defined.

This is a great step, I can use all my nodes from now on!
Thank you very much for your support!

Hi PJR,
thanks a lot! This is obvious. Please apologize that I didn't take a look at this site. So the MyTransportRS485.cpp is loaded only in case of defining MY_HWSERIAL... This explains why it was not working after skipping the MY_HWSERIAL definition.
Unfortunately I was not able to run another test now but I hope it will come up soon.
The changes regarding softwareSerial would be a great help for those who are not able to use the altSoftSerial pins.
Once it is running stable I will post a request @hek to ask for implementation.
I will come back with more tests.

PS: It seams that during compilation it loads also the AltSoftSerial.cpp. In case of use of the SoftwareSerial it would be unnecessary overhead, of course. Is there a reason why it is loaded at this stage? I would rather load it at MyTransportXYZ.cpp.

I did it like this:

#if defined(__linux__)
SerialPort _dev = SerialPort(MY_RS485_HWSERIAL);
#elif defined(MY_RS485_SWSERIAL)
SoftwareSerial& _dev = MY_RS485_SWSERIAL;
#elif defined(MY_RS485_HWSERIAL)
HardwareSerial& _dev = MY_RS485_HWSERIAL;
#else
AltSoftSerial _dev;
#endif

The Arduino code is extended by:

// Enable debug prints to serial monitor
#define MY_DEBUG

// Enable RS485 transport layer
#define MY_RS485

// Define this to enables DE-pin management on defined pin
#define MY_RS485_DE_PIN 3

// Set RS485 baud rate to use
#define MY_RS485_BAUD_RATE 9600

// Enable this if RS485 is connected to a hardware serial port
//#define MY_RS485_HWSERIAL Serial1

// Enable this if RS485 is connected to Software Serial port:
#include <SoftwareSerial.h>
SoftwareSerial softSerial(4, 2); //rx, tx
#define MY_RS485_SWSERIAL softSerial

#include <MySensors.h>

Hi PJR,
would you mind explaining me the reason for defining MY_RS485_HWSERIAL?
Thank you,
by kduino

HI PJR,
thank you very much for your reply. I did as you suggested but were not able to test during the last days.
Today I wired it up and it worked. Unfortunately updating some sensor code it is currently not working but as soon as possible I will post the whole sketch together with the adapted MyTransportRS485.ccp.

Hi,
I think I got to the specific part of code:

From Github MySensors/hal/transport/MyTransportRS485.cpp
https://github.com/mysensors/MySensors/blob/development/hal/transport/MyTransportRS485.cpp#L88

#if defined(__linux__)
SerialPort _dev = SerialPort(MY_RS485_HWSERIAL);
#elif defined(MY_RS485_HWSERIAL)
HardwareSerial& _dev = MY_RS485_HWSERIAL;
#else
AltSoftSerial _dev;
#endif

But unfortunately I am not able to change it to the softwareSerial option. How would the code look like if I would make an additional if for the softwareSerial?
Help is very appreciated.

Hi Kisse66,

thank you very much for this advice. Most of the forum writers are pointing on the terminating resistors, but in my experience they are not the key.
I put two 680R from B to GND and A to 5V and the reliability I experienced has improved tremendously!
Thank you for the hint.

Another question I have: The gateway is receiving the messages now but there is no ACK. How can I ask for an ack for security relevant messages?

Thank you

Hi,
@admins
an advice about the MY_NODE_ID in the how to for the rs485 section would be helpful. I think, there are at least the double of the people trying for hours until they give up. Only some of them take the efforts to register and login here to get useful information...
By kduino

@hek
I used some time to get further. As my tests show I can easily use the Arduino nano on pin 8 and 9, but the strategy of using SoftwareSerial you mentioned is not working.
See what I did below. The problem is now as follows:
If I state the HW_SERIAL command before the inclusion of mysensors.h the hardware serial is somehow not initialized and therefore throws an error on compilation. Only hardware serial ports are allowed.
If I state the HW_SERIAL command after the inclusion of mysensors.h the inlcusion has no effect, thus the defined pins are not rx and tx.
Do you know any advice for that?

Thank you so much for your support!

Hi,
Trank you all for your support. I got in running finally.
I reassembled the complete thing on the breadboard. Then I connected the wires directly (rx-tx and tx-rx). After changing the position of the inclusion of mysensors.h for some times and using the standard pins and the preset node id it worked.
Then I went further to test software serial lib which worked great. Then I extended the model to use the rs485 and after some adaptation of the wires (it's always the wires after some frustrating nights) it worked.
For understanding I integrated also two led to signaling the sending via the de pin. This helped a lot.
As this was working correctly I turned up the speed. Ok, 250.000 bps were too much, but 115.200 were running without any complaints. On a breadboard though but without any cable adaption or resistor as final terminator.
So for this topic we can conclude that if rs485 is not even running on 9600 bps on a breadboard, it's not because of the cable or the terminating resistors. In this setting it should work anyway. Unless you have no bug somewhere else....
So for all my followers again thank you very much. I can only suggest to myself to reassemble the test unit completely to rule out any wrong connections....
Bye kduino
