Datasheet

Upload this sketch and open the Serial Monitor and it should perform a factory reset for you:

AT+FACTORYRESET

You can also perform a factory reset by sending the AT+FACTORYRESET command to your Bluefruit LE module in your favorite terminal

emulator or using the ATCommand (http://adafru.it/iCk) example sketch.

AT+FACTORYRESET

This command will also cause the device to reset.

Factory Reset via FCTR Test Pad

On the bottom of the Bluefruit LE Friend board or shields there is a test pad or pin that exposes the Factory Reset pin on the modules (marked

FCR or F.RST). Setting this pad low when the device is powered up will cause a factory reset at startup.
