Description
i have 2 Esp32 nodemcu, they connect each other with esp now that send 2 thins: The first is the heartbeat that check if the connection between the 2 esp exist and show a led status. The second is the weight scale data that send it from ethernet udp to the esp32 and the esp32 send it over esp32 to the second one. the program works really well, send all the data, and says the connection is stablished, but after 2 or more days the esp32 stops working, the led keep blinking like the connection exist, but the esp32 not response, i have a switch that you can change the esp32 to habilitate the OTA and wifi AP so you can program it. but the switch don't work is like it get stucked, the worst part is i put a Watchdog but i think it didin't work, i can't see the log of the problem because if i connect to usb start working normally, i change the power supply 3 times and i have a capacitor filter, all this in 5v in VIN
