dollar signs) from either the remote Bluetooth connection or the local serial port connection. You must enter
command mode within 60 seconds (configurable by setting the config timer).
NOTE: Only one client can make connection to FireFly slave at a time. As a master, it is possible to make
multiple connections from FireFly, but only in a point-to-point, serialized fashion. At this time Roving
Networks devices do not support multipoint master mode.
Operational modes can be set using the SM command
Slave mode (SM,0)
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.
Master Mode (SM,1)
This mode is useful when the device wants to initiate connections (not receive them). In this mode
the device will NOT be discoverable or connectable.
Trigger Master Mode (SM,2)
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 remain open until a
configurable idle timer (1 to 255 seconds) expires with no data being received, or a configurable
BREAK character is seen.
Auto-connect (Master Mode) (SM,3)
This mode can be set by command, or by setting the external dip switch 3 during power up by the
on the FireFly and BluePort serial adapter or setting high PIO6 on the Bluetooth modules. 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.
Auto-connect (DTR Mode) (SM,4)
This mode must be set by command. This mode operates like Auto-Connect Master mode, except
that the connection and disconnection are controlled by the external dip switch 3 on the FireFly and
BluePort serial adapter and PIO6 on the Bluetooth modules. Setting the Switch ON/PIO6 high
will initiate auto-connect process, and OFF/PIO6 low will cause a disconnect.
Auto-connect ANY Mode (SM,5)
This mode must be set by command. This mode operates like Auto-connect 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.
