Open Plotter & Navionics AIS support

[pinguino]

I don't think Navionics will use the NMEA GPS info. The KPLEX is certainly spitting it out but I don't think Navionics has coded to look for anything but the AIS info.

In fact I have personally been able to verify that Navionics can use external GPS data to position itself while we are using the function of creating our own live sonar chart.

I have specifically checked that at the same time that it reads the depth data, if it receives the GPS data we can also deactivate the phone's internal GPS and position itself on the chart with the external GPS data. It is true that it will show an error message asking us not to deactivate the internal GPS but we can ignore it and use the NMEA0183 data from the wifi network.

With the new AIS display function that has recently appeared there is no problem. Everything works ok. The GPS data for position, the depth data to create the sonar chart and the AIS data from the surrounding ships.

The real problem that you will find some with these instructions is that although they are correct, in openplotter 1.x.x does not always work well. Sometimes - few - it does. But most of the time it doesn't work.

Fortunately with the next version 2.x.x of openplotter works ok 100% of the time. I have been able to prove it.
