Didin’t have time to answer, had a lot work at the farm. The problem was in micro USB cable!
But now, I have another problem. System is working, but sometimes IMU is not. Like yesterday the whole day IMU was working good, today in the morning no connection to IMU, first it was RED in AgIO, now no color. And it is not first time. If it works it works good all day, if it’s not it’s not. Maybe this can help? Found in one of topics: Solved! Added delay(2000) after void setup to ino at initialisation.
