Garmin plotter crashes nmea communication

[rmvdmrl]

So if the  chart plotter sends the message  GPAPB, then pypilot should  not switch modes, and  it should only change the course if  it is in the correct mode.

Otherwise **APB will change to the  needed mode?     Would this work for you?   I  think it's acceptable for now.

Hi Sean,

That is indeed what what i was thinking. I think this would be great for now, it keeps both functionality. Do you think checking each GPAPB line (mostly empty) would be an issue (performance) or would it be better to only proces and check the GPAPB if it is longer than an empty GPAPB (and or **APB)?, Perhaps with a future update if possible it may be nice to have an extra mode "Waypoint" or "Route" steering" combined with audio alarm (beeper on one of the gpio pins) and confirmation on course changes for arival and heading to the next waypoint.

Greetings and thanks for looking into this, Rob
