If I see this correctly, then an external IMU could communicate via DroneCAN message ID 1003.
And if I understand correctly, the message type 1003 is not implemented in Ardupilot.
Hence my question: Are there any plans to implement this message type in Ardupilot in the near future?
Which ArduPulot FW version are you using.
You might be understanding incorrectly, it might already be implemented in Ardupilot master branch aka. 4.5.-dev a.k.a latest. Have you tested that?
OK. thanks for the quick reply!
No, so far we are testing and flying with Plan 4.4.2.
Then we will test Plane 4.5-Dev.
