Mftp download of parameters from camera component to QGC and MP

General

Hello,

I’m implementing camera device firmware (MAV_COMP_ID_CAMERA) . I have fully working Param EXT configuration together with camera definition XML file shared via MFTP protocol.

I would like to share also classic parameter list and parameter description via mftp protocol to save some initiation time.

How this works? I tried multiple approaches, however MissionPlanner or QGC does not download / request parameters.

I tried to broadcast component_metadata packet with URI to param list.
I tried to broadcast component_information packet with URI to param list.
I tried to follow this manual:

Both messages when broadcasted are ignored by MP and QGC.
I can see they are received in the MavLink inspector:

Component information protocol seems not to be initiated (requested) by GCS.

What is correct procedure?

It needs to have its own heartbeat so you can select it from the drop down under the connect button on mission planner.

Thanks for that tip, of course heartbeat is emited and I see “Camera” in the devices list:

Mission Planner only sends “Reset all sessions” via mftp initially, no further ftp communication.
