2.7.4 Auto-Connect Master Mode (SM,3)
In this mode, the device automatically reconnects to the stored address on power-up
when the connection is lost. This mode can be set by command, or by setting the exter-
nal DIP switch 3 during power-up. If an address is not stored and DIP switch 2 is set,
the device performs an inquiry process and the first device found that matches the
Class Of Device (COD) is stored. In this mode, high-speed data is passed without being
interpreted which means the connection cannot be broken through commands or soft-
ware break characters. If a disconnect occurs, the device attempts to reconnect until
successful.
2.7.5 Auto-Connect DTR Mode (SM,4)
This mode must be set by command. It operates like Auto-Connect Master Mode,
except that user has to control the connection and disconnection with DIP switch 3.
Turning the DIP switch on initiates the auto-connect process, while turning the DIP
switch off causes a disconnect.
2.7.6 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 DIP switch is set, an inquiry is performed and the first
device found is connected. The stored address is not used, and the address found is
never stored.
2.7.7 Pairing Mode (SM,6)
In this mode, the device attempts to connect with the remote device that matches the
stored remote address. To set the remote address, use the SR command.
2.8 CONFIGURATION SWITCHES
The evaluation boards have small configuration switches at the bottom. These can be
configured or flipped using a paper clip or a small screwdriver. Holding the board with
the PCB antenna facing to the right, the switch numbering and on/off positions are
shown in Figure 2-4.
