ESP8266 Community Forum

I am running a generic ESP8266 board connected to a Mint 18 system. I have programmed it with the Arduino IDE and am monitoring the output on the Serial Monitor. The board is outputting a small block of data every hour. After a few (3 or 4) hours it stops. It appears to have dropped the serial connection.

Has anyone seen that before? I don't have anything else running that uses serial ports.

Thanks,
