I am looking for simple wi-fi to uart solution to interface with microcontroller. I have started with pfodWifiConfig
and arduino sketch associated with it but I am having hard time to get success. My hardware is ESP-201-DEV-bw. Can anyone help me to get on right track?
Thanks

- Fri Dec 30, 2016 1:15 am #60131 What firmware? You just need to send the right AT commands through UART to the ESP8266.

Code: Select allAT+CWMODE=1\r\n

will put it in station (client) mode and

Code: Select allAT+CWJAP="ssid","password"\r\n

will connect to a given network.

If you are having a hard time sending/receiving through UART, make sure you have the correct baud rate. 115200 is what usually works but if you have an old enough firmware then you'll want to use 9600.
