OpenCPN freezing when serial GPS connected

[Sailoog]

Hello, 

I also used openplotter and opencpn last year and there was no problem at all. At some point the Opencpn begun to freeze. I found out that as soon as I make the signalK connection Opencpn freezes in few seconds. I can get GPS position data but not data of the I2C sensors im my case Compass and BME280. 

The network NMEA 0183 connection (TCP - localhost - 10110) doesn't solwe this problem. 
Is there a workaround?

If opencpn still freezes having only NMEA 0183 data and the Signal k connection is not enabled, you are suffering a different issue.

This issue is about opencpn trying to digest null values in signal k data.
