Hi,
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

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.

The following is a WiFi to UART bridge.
