2. Modes of Operation
0- Slave mode – This is the default mode, whereby other Bluetooth devices can discover and
connect to the device. Outbound connections can also be made in this mode.
1- Master Mode - This mode is useful when the device only wants to initiate connections (not
receive them). In this mode the device will NOT be discoverable or connectable.
2- Trigger Master Mode - In this mode, the device will automatically connect to the pre
configured remote slave address when a character (or characters( are received on the local
UART. Connection will continue until a configurable idle timer (1 to 255 seconds) determines
that no more data is being received, or a configurable BREAK character is seen.
3-Auto-connect Master Mode- This mode can be set by command, or by sensing of Switch 3
during powerup on the FireFly.(PIO6 high on the module). If this mode is set, the device will
initiate a connection to the pre-stored remote address immediately upon power up. If no
address is stored, an inquiry process will be attempted and the first device found that matches
the COD will be stored. In this mode, data is passed without being interpreted by the Blueport
(high speed), hence the connection cannot be broken via command. If disconnect occurs, the
device will attempt to re-connect until successful.
4-Auto-connect DTR Mode- This mode must be set by command. This mode operates like
mode 3 Auto-Connect, except that the connection and disconnection are controlled by Switch 3
on the FireFly.(PIO6 on the module). Setting the Switch ON/PIO6 high will initiate auto-
connect process, and OFF/PIO6 low will cause a disconnect.
5-Auto-connect ANY Mode- This mode must be set by command. This mode operates like
mode 4 DTR mode, except that each time the Switch/PIO is set, an inquiry is performed and
the first device found is connected. The stored address is NOT used, and the found address is
never stored.
