I’m using the Holybro Pix32v5 in combination with the Base Mini.
I need additional MavLink-communication (OSD, Receiver), using telemetry 3 (serial 4) & telemetry 4 (serial 5).
What I did:
In Ardupilot, serial 4 & 5 are configured as MavLink (2), but there is still no communication.
I checked the wiring on serials 4 & 5: this is correct (Rx & Tx).
I swapped the connectors from serials 4 & 5 with serial1 & serial 2 (telemetry 1 & 2): MavLink-communication works.
Based on the documentation I found, serials 4, 5 ,& 6 are disabled by default.
How can I activate serial 4 & 5 to use MavLink?
