Has anyone came across this issue and know how to solve it. I’m busy setting up and Hexa with a Pixhawk. My first one was a APM 2.8 . I have gone through all the calibrations but for some reason when I want to calibrate the compass again I get no readings. If shows Got + 0 samples, Compass 1 error: 99, Compass 2 error: 99, Compass 3 error: 99.

Can anyone help?
Looks like your Pixhawk (or at least its compass) is not talking to the ground station. Are you connected via radios or USB? Check that you have a good connection (e.g. verify that HUD is moving when you move the copter). It doesn’t look like it’s a cabling issue (if you also have an external compass) as even the internal one is not read.
Perhaps more important, have you selected “Pixhawk/PX4” in compass main screen (vs APM) and are “enable compass” related box checked? This mail help:
Thanks Oliver. I’ll give it a try.
I’m using USB and did select Pxhawk/PX4
No luck. I still don;t get any reading from the compass. Still getting the "Compass 1 error:99
I’m having also a lot of problems with compass calibration .
I suggest to try using USB connection , datas will arrive more quickly .
Even if the compass will continue to show error:99 continue the calibration moving the copter , you should see the error disappear after a while.
