ACTION Commands
Begin by sending the inquiry scan command: I,
If the modem finds any modules, you can try sending the connect command: C,
< to connect to one of them. The modem in the example above found one devices in range, by sending the C,0006664FAE18 command, we can attempt to connect to one of them. After sending the connect command, the device will respond with "TRYING", which will be followed by either "CONNECT failed" or the connection will be successful. After a successful connection we immediately enter data mode, and the modem becomes a pipeline. Any characters sent from one Bluetooth device will be sent to the other, and vice-versa.
