ESP8266 Community Forum

Hi Buddies,

We have to us the ESP8266 modules in a weak and noisy enviroment And we often encountered a reconnect callback with error code of ESPCONN_TIMEOUT, during the transmission. We tried to attached a gain antenna, but no obvious improvement.

How to process this issue?

Thanks in advance

Start using debugging the actual connection. It may not be that. Set up a continuous ping from your PC to the ESP and see whether it keeps working all of the time.
