Bluetooth device supporting Bluetooth SPP (Serial Port Profile). For Bluetooth
wireless connections to an SD, first make another SD ‘Discoverable’ and
‘Connectable’. In this case, refer to section 3.3 before following the
instructions below.
1. First check the status of the SD by entering ‘AT+BTINFO?’. The SD
response is comprised of BD_ADDR, Device Name, Operating Mode,
Operating Status, Authentication and Encryption flags. To make connection
to other Bluetooth devices, the operating status of the first SD should be
‘STANDBY’. A ‘PENDING’ operating status of the first SD indicates the
unit is busy with another operation. In this case, cancel the ongoing
operation by entering the ‘AT+BTCANCEL’ command.
2. Search other local Bluetooth devices by entering the ‘AT+BTINQ?’ command.
3. Check the search list. Enter ‘ATD’ command in the BD_ADDR of any
Bluetooth device for connection. During the connection process, the
STATUS LED will flash green every second.
4. Connection is indicated by the SD returning a ‘CONNECT’ message and
displaying a green STATUS LED.
