Can not compile on Arduino Nano ESP 32

[eiten]

Your board seems to use USBCDC to communicate with the PC. So in the file /hal/architecture/ESP32/MyHwESP32.cpp, line 30, you have to change MY_SERIALDEVICE.begin(MY_BAUD_RATE, SERIAL_8N1); to MY_SERIALDEVICE.begin(MY_BAUD_RATE);.
Furthermore, as ESP32 implements the function sleep(uint32_t) iself, you need to change line 147 in the sketch from sleep(SLEEP_TIME); to sleep(SLEEP_TIME, false);.

Hope this helps!

As an additional info, sleep will not work on the ESP in version 2.3.2. Try the developement branch from the github if you need sleep, there I implemented this.

@eiten Thx for the info.
"Try the developement branch from the github": can you give me the url?

[eiten]

@ctodor of course:
https://github.com/mysensors/MySensors/tree/development does contain sleep code for ESP. You can download the library here as a zip file.

@ctodor did you succeed?

@eiten
Sorry for the late response, but I didn't had time to work on it until today.

Yes, I was able to compile but not to upload. After "uploading", the Arduino NANO ESP 32 disconects from the PC.
I must reset the board in order to be able to upload another sketch.

OK, so I suppose the build flags are incorrect. Do you use PlatformIO? Then, you could try:

build_flags = 
	-D ARDUINO_USB_MODE=1
	-D ARDUINO_USB_CDC_ON_BOOT=1

If you are on the Arduino IDE, you have to set Tools -> USB-Mode -> CDC-Mode. Ore something similar, I don't have the Arduino IDE installed ATM. IIRC, monitor speed must be set to 460800.

@eiten Yep, I was able to upload the sketch after I've set Tools -> USB-Mode -> CDC-Mode.
Thank you for your help.

Well, I think I rushed with the conclusion.
Somehow, the bord is now in infinite boot loop:

0;255;3;0;14;Gateway startup complete.
0;255;0;0;18;2.3.2

repetes over and over

That's strange. Is it exactly the code from above? It seems, it is in gateway mode, but in your sketch, you commented out the gateway option...

[ctodor]

@eiten You are right. It is not the same sketch. The previuos sketch seems to work fine (I used it just to make sure I am able to compile and upload).
Now I'm trying to upload a sketch where the ardunio runs as gateway and this is what a need , a gateway that receives messages from a few magnetic door sensors.
But please, don't waste your time with me. I think I'm going to write my simple protocol to do such a simple task.

Thank you very much for your effort.

@ctodor You are very welcome
