Get only Mavlink heartbit messages

Posted by Oren Lewkowicz on January 11, 2016 at 2:33am

Hi,

I wrote a java program to the Pixhawk via Mavlink.
As part of the connection i send heartbit every sec and ask for MAV_DATA_STREAM_ALL.

The problem is that I receive only heartbit messages.

When i try to connect to APM i do get all Mavlink messages.
If i connect the Pixhawk trough mission planner and then run my code i do get all messages.

Any thoughts?

Thanks,
Oren

MAV_DATA_STREAM_ALL doesn't get anything. ;-)

My suggestion is donwload the the ardupilot code and then look at GCS_MAVLink.cpp for the vehicel you are intersted in. You can then see how each request you make is processed.

Alos you can look at how a GCS does it. See APM Planner 2.0 as an example

Hope that helps :)

  Hi Bill,
  
  Thanks for your prompt reply.
  
  I managed to solve the issue by using mavlink.Messages.pixhawk package instead of org.mavlink.messages.
  
  Everything is working now.
  
  Cheers,
  
  Oren
