Crossfire Serial Bridge (Bluetooth) stops working if craft is armed

[KayCox]

Got my crossfire rx connected over UART for using serial bridge from the CRSF TX to my iPad running mobile fight app. All works fine, got full telemetry and can do any changes via the app. As soon as craft is armed, the transmission closes completely. No more telemetry is received.
Any ideas?

[Tygrys-1]

Have you enabled MSP telemetry on this port?

[fiam]

You have enabled MSP and something else on that port. Enable MSP and nothing else.

[stronnag]

The something else is MAVLINK. It requires that whatever the GCS is to support it. I don't think Mobile Flight does.

[digitalentity]

Important thing to remember about enabling MSP together with telemetry (MAVLink, LTM etc) on the same UART is that they don't work together at once.

If craft is disarmed - port is connected to MSP If craft is armed - port is connected to telemetry and disconnected from MSP

[jpbarraca]

INAV Configurator could show a warning with this information when the port has multiple purposes.
