    Ping Test

        No action is taken by the Bluetooth, it simply acknowledges with “OK” letting you know communication was successful.

        Send: AT

        Response: OK

    Set Baud Rate

        Sets the Bluetooth UART baud rate. Baud rate is set by an hexadecimal index from '1' to 'C'.

        Indexes are: 1:1200, 2:2400, 3:4800, 4:9600, 5:19200, 6:38400, 7:57600, 8:115200, 9:230400, A:460800, B:921600, C:1382400

        Send: AT+BAUD<index>

        Response: OK<baud rate>

    Set Bluetooth Device Name

        Sets Bluetooth Device Name

        Send: AT+NAME<device name>

        Response: OKsetname

    Set Bluetooth PIN Code

        Sets the security code needed to connect to the device.

        Send: AT+PIN<4 digit code>

        Response: OK<4 digit code>
