Figure 6. Pair with the Bluetooth Adapter

NOTE: You only need to pair with the adapter once.

Connecting

To establish a Bluetooth connection, open the adapter’s COM port from your application or a terminal emulator. When the

COM port is open, the adapter’s green LED changes from blinking to solid on. The device remains connected until you

close the COM port or turn off the Bluetooth adapter.

Security Modes

The Bluetooth adapter supports authentication. If the local or remote Bluetooth device has authentication enabled, a pin

code is required the first time a connection is attempted. The pin code is a series of numbers or characters.

NOTE: The default pin code for Roving Networks Bluetooth adapters and modules is 1234.

After you enter the pin code, the Bluetooth devices compare them. If they match, a link key is generated and stored.

Usually, but not always, the remote device stores the link key. For subsequent connections, the devices compare link keys.

If they are correct, you do not need to re-enter the pin code.

If the remote device is a PC or PDA, the user generally is prompted to enter this pin code. To remove the stored link key on

the remote device, you typically “unpair” or remove the device from the Bluetooth manager. You can change the pin code

to remove the link key on the Bluetooth adapter, forcing a new pin code exchange to occur upon subsequent connection

attempts.

NOTE: Only one master can connect to the Bluetooth adapter at a time.
