MySensors 2.0 Serial Gateway
Do not be afraid to build your own MySensors Serial Gateway with NRF24L01 and use it with MyController server ! Just need to have the original Arduino Nano, or clone with FT232RL USB chip. Do not use the Arduino model with CH340 chip, it's not stable ! In Mycontroller server I used the driver: jSerialComm. And everything works as it should !
Strange that you see instabillity with the CH340 chip.
I have a mix of original chips and the CH340 chips and never encountered any issue....
btw, nice enclosure!!! looks great!
