Introduction
Onboard the ESP8266 WIFI module has three work modes:STA (client), AP (hot), the STA + Ap( hot +client), according to the workings of a module to the corresponding choice of WIFI module working mode.Module need before use serial debugging software and USB to TTL module send serial command was carried out on the WIFI module configuration (don’t power outages after configuration is complete, as some of the parameters of WIFI module cannot be saved when the power is cut off), mobile phone and WIFI module after establishing a network connection can use the phone APP control relay.
