would for local configuration above. When finished configuring, be sure to either reset the device, or
Send th
e “---“command, which will exit configuration mode and allow data to pass normally.
NOTE 2: You can only enter command mode remotely over Bluetooth if you have made a connection
and sent the $$$ within the “config timer” window after powerup. This can be modified, the default
config timer expires 60 seconds after powerup. Once the timer has expired, any data sent to the device
will pass unmodified and unrecognized by the command interpreter. The timer can be set to any value
from 0 (disable remote configuration) to 0xFF hex , which allows continuous (no timeout) configuration.
WARNING: Configuration (local or remote) is NEVER enabled when the device is in auto-mode and is
connected over Bluetooth.

3.3 Using the PIO pins/DIP switches to perform quick configuration
Factory Reset-
Set this switch/PIO on powerup. This arms the reset function. Then toggle the
switch/PIO 3 times and all settings in the device (other than the Bluetooth name) will return to defaults.
Auto Discovery/Pairing Mode
-
Used with Switch3/PIO6. If Switch3/PIO6 also set,, the device will
perform a device Inquiry Scan, searching for a partner Device with a special matching class, (0x55AA)
and once found, store the address of such device into the remote address field, and then auto-connect
to the remote device. If Switch3/PIO6 is NOT set, the device will enter slave mode with the special
matching class, waiting to be found by the master. This mode is usually set once on both ends of a pair
of devices, for instant “cable replacement”, and then removed
.
Auto Connect mode
–
This is equivalent to auto-master mode 3 in software. The device will connect to
the stored address. If Switch2/PIO3 is also set, new discovery/pairing can be made, see above.
Baud Rate select -
used to configure 9600 or 115K default baudrate. If the baudrate is configured in
software, this switch is ignored.
