You may want to specify in more detail what your app should do.

Use the mode command. You need to use a serial connection to change the mode property before you can send AT commands over a wireless connection.


AT+MODEx It changes the way the module processes AT commands:

AT+MODE0 (default value): Only accept AT commands over the serial connection (RX/TX) until a Bluetooth connection is made.Once a connection is established AT commands are treated as data.

AT+MODE2 Same as MODE0 but once a connection is established, AT commands can be sent over the Bluetooth connection. This allows you to remotely change the value of GPIO pins.
