Can you provide more detailed information of the issue? What you are trying to accomplish, what is failing, etc. I am not sure it is very clear with your previous message. Thanks.

on the upper computer I use of "mavlink_parse_char" parses the mavlink message packet come from one-chip computer . When the message packet send by "mavlink_msg_heartbeat_send" that can be successful(return 1), but if the message packet send by "mavlink_msg_global_position_int_send" will be filed(return 0).

If I got it correctly, you are connecting QGC somehow with a companion computer, and for some reason mavlink messaging between both is failing, correct?

Yes, That's true. I can receive the information package, but parsing failed. (Heartbeat packet can be parsed successfully. Others can't succeed )

I understand. I don't think this is the scope of QGC issues. To me it seems you are having trouble working with mavlink itself, so I really think you should ask for help on dedicated mavlink threads.

In QGC you can see lots of examples all around of how to send, and parse mavlink channels.

I think we can close this issue for now.
