OFF = 115K (can be overridden by software baud rate configuration command),
ON = 9600 (ignores software baudrate configuration)
In slave mode, sets a special class of device that is used the master to auto connect. If
Switch 3 also ON, the device performs a search, stores, and connects to a remote slave
which has this switch 2 set.
Device acts as Bluetooth master, auto-connects to a stored remote address. First set the
Bluetooth address of the slave device using the SR command or through instant cable
replacement settings.
