Issue: Ardupilot Returning Gibberish!

Hi Folks,

I have been working on viewing the data returned by the ardupilot.

I use the APM terminal to view the data returned through the serial port

however there is an issue. I get an error mesage (error reading com port) after some data 

about free memory and initialization, and ardupilot starts returning some gibberish.

I have tried uploading the latest code through APM again with the correct baudrate but same result.

Any ideas?

It's MAVLink binary, not ASCII. You can't read it the terminal.

Thanks for replying Chris.

I need to be able get some sensory data from the system such as

GPS, IMU, etc. to display on a ground station software. Do you know how

can I see the data returned and /or parse it?

You need to write a MAVLink parser.
