Connection to autopilot with QGroundControl
The GPS module is connected to the autopilot via the Telem2 port on the autopilot. The default baud rate is incorrect and must be changed. Linnet Mosaic-X5 has a baud rate of 115200 bit/s, while Linnet ZED-F9P has a baud rate of 38400 bit/s.
Method 1 : Vehicle parameters
The baud rate is modified in the vehicle parameters tab with the SER_TEL2_BAUD parameter. The vehicle must be rebooted for the modification to take effect.
The connection status can then be checked with the status command in the MAVLink console tool, available in the analyze tools tab.

If the module is connected, then the status command should return the message below. It may take a few seconds to detect the module.
Method 2 : MAVLink console
The MAVLink console tool is available in the analyze tools tab. First, stop the gps module.
gps stop
Then start the module, specifying the device and baud rate. The corresponding device is specified in the PX4 documentation. For the Pixhawk6C autopilot, for example, the device is /dev/ttyS3.
Mosaic-X5 requires a baud rate of 115200 bit/s.
gps start -d /dev/ttyS3 -b 115200
ZED-F9P requires a baud rate of 38400 bit/s.
gps start -d /dev/ttyS3 -b 38400
The connection status can then be checked with the status command in the MAVLink console tool, available in the analyze tools tab.

If the module is connected, then the status command should return the message below.
