It is often useful to be able to perform configuration remotely over a Bluetooth connection. To do this,
connect to the device over Bluetooth, and using your terminal emulator, perform the same steps as you would
for local configuration above. When finished configuring, be sure to either reset the device, or Send the “---
“command, which will exit configuration mode and allow data to pass normally.
NOTE: 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 255 decimal , which allows continuous (no timeout) configuration. WARNING:
Configuration mode (local or remote) is NEVER enabled when the device is in auto-mode and is connected
over Bluetooth.

Auto Discovery/Pairing Mode -
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
