If you are using RTK solution and you lose your RTK radio link, the device defaults
to the next highest mode, being either Atlas high precision service or SBAS (if
available). If the new signal becomes unusable, the next mode will be selected (for
example Beacon or External RTCM). Finally, if no correction signals are available,
the device defaults to Autonomous.

The Bluetooth port is fixed and should not be changed.
- GNSS models: Bluetooth baud rate is 230400.
- GPS models: Bluetooth baud rate is 115200.
When setting up COM port parameters in a software that will communicate via
Bluetooth to the SXblue receiver, any baud rate can be specified, but in order to
avoid communication overflow, care must be taken in properly selecting the
number of sentences output on a port at a particular baud rate. The Serial and
USB ports can be configured from 2400 to 115200 baud.
