... When data is written to the UART, the module constructs the Bluetooth packet and sends it out over the Bluetooth SPP connection. Thus, the entire process of sending/receiving data to the host is transparent to the end microprocessor.

... Bluetooth device connected and powered on, run a terminal emulator and open the COM port to which the cable is connected. You should configure the virtual COM port connected to the RN-41-EK or RN-42-EK USB interface with the default settings (115,200 Kbps baud, no parity, 8 bits, 1 stop bit). You can use command mode through the UART interface via the USB connector at any time when the device does NOT have a Bluetooth connection, as well as under certain conditions ...

... If the configuration timer expires while the device is in command mode, the device does not go into fast data mode after exiting command mode. When you enter a valid command, the module returns AOK. It returns ERR for an invalid command and ? for unrecognized com- mands. Type h <cr> to see a list of commands. ...

... Auto-Connect Master Mode (SM,3)—In this mode, the device makes connections automat- ically on power-up and re-connects when the connection is lost. This mode can be set by command setting the external dipswitch 3 during power up address is not stored, the device performs an inquiry process and the first device found that matches the COD is stored. In this mode, high-speed data is passed without being interpreted ...
