I’m trying to connect a MAVLink component to a pixhawk cube and get it’s messages passed through so that it shows up in a GCS.
This is my 2nd attempt at this; I tried already few months back and failed. Now I fail again, so I thought I may ask.
I do have a MAVLink component with integrated gimbal and camera, i.e. it behaves like two MAVLink components, and wish to connect it to TELEM2 of a cube/pixhwak2. Then the cube is loaded with ArduPilot it all works fine. I have now flashed PX4 latest stable v1.10.0 and use QGC
latest stable v3.5.6 (master of ca 2 weeks ago).
I’ve set the airframe, and did the sensor calibrations, and have set
MAV_1_CONFIG = TELEM2
MAV_1_FORWARD = Enabled
MAV_1_MODE = Custom
MAV_1_RATE = 100000 B/s
MAV_PROTO_VER = Always use version2
SER_TEL2_BAUD = 115200 8N1
but otherwise the params are at their default.
When I connect a USB-TTL adapter to TELEM2 I can see the cube emitting heartbeats. I also can connect via TELEM2 to the cube with MissionPlanner.
HOWEVER: I DO NOT see the MAVLink components GIMBAL1 and CAMERA1 on the cube’s USB port !!! Not even their heartbeats, and accordingly both MissionPlanner and QGC don’t realize the presence of the components when connected to the cube/PX4.
To me it looks as if their MAVLink messages including their heartbeats are not routed/forwarded to the USB, but I could not find/identify any parameter which would allow me to enable that.
I’m obviously doing something simple wrong. Any help would be much appreciated.
