Any info/suggestion is highly appreciated.
Thank you

Here are the pictures:

But my question (maybe stupid question) is: It is possible the the radio module to be broken only on the "send side"?

Thank you.

@mfalkvidd multimeter

Update: it seems the problem was the DC-DC convertor. I have replace it with an extwrnal power source and now it works.
I still don't understand what was wrong there because the voltage on the radio module was correct:3.3V

@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.

@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:

repetes over and over

@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.

@eiten

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

@eiten
It is the SoilMoistSensor.ino skecth from MySensor example.

Hi,
I'm trying to compile one of the example on Arduino Nano ESP32. (MySensors version 2.3.2)
Am I doing something wrong?

@yury may be node radio is HCW somehow? no, it is not.

I'll try to create a new board and give feedback.
