Bug in OCPN ?
#1
I also this over in OPCN's forum. It is I think a bug in OCPN but might be something else. 

Running on Pi 3 with everything up to date.

The heading of the ownship icon freezes when autofollow is on. Manually move the chart or release autofollow and the icon starts indicating the correct heading again.

Heading comes from HDG sentence 

In a possibly connected issue the Ownship icon does not recognise the heading when the only sentence into OCPN is HDM; although the the dashboard does recognise HDM (but ironically the display box on the Dash is labelled HDG; which is isn't). 

Anybody else seeing this?

There are various heading sentences, and some are magnetic, others are not.   OpenCPN likely doesn't handle all of them the same way and probably has bugs.   I can say I never saw this problem using my autopilot (pypilot) which outputs compass heading from the mpu9255 to opencpn

Sean, Can you please tell me what sentences that you are using for ships heading so that I can try to replicate your setup and try to get to the bottom of this? 

Not being able to see autofollow when I also want to see the heading line is quite a serious bug for me.
