I’ve had a little problem with LoRa Esp32 V2 boards.
I have an application with 1km range betwen two LoRa module, the sender module send a bit data each 10s and the receiver keep all time listing the data, the receiver is not set to sleep any time.
But some times the module get stuck, the code too, and the display turns off too. The orange LED (power) still shining but not strong that before, seems almost off.
I’ve implemented a watchdog to avoid that, but it didn’t work.
Does this boards have a defult setting to sleep that i need change? i think no because i have other boards with the same applicantion working fine.
Can be an overvoltage that was bugging the module? or a noise in the AC power(i’m using Hilink 220Vac to 5Vdc with filters in both sides)?
If someone can help me.
