VamsiTungala opened this issue · comments

Hello

I am trying to integrate UM982 with Pixhawk cube orange on X500 V2. I followed all the instructions as per the Pixhawk website but could not get the heading from UM982. Later I checked output of UM982 with UPrecise from which i observed was
GPS output:

$GNGGA,091510.00,5057.25505246,N,00653.73013267,E,5,24,0.6,48.3615,M,46.9156,M,1.0,0*54

Last data command has heading data but autopilot device code does not have any parser to use that data.
So I had to change UM982 output to get it working.
is it supposed to be like that?
