The APRS works fine.
the setup is here on my desk, with some instruments connected. like a gps32 in simulation mode, a gps
repeater display, nasa wind
, and also some seatalk equipment
connection to my laptop
3.3.1419 running on there.
All is connected through my own design wifi
multiplexer. Ive designed the hardware
an d software
for that myself.
there is a switch input. That can be selected to be used as a man overboard
switch. The multiplexer uses the position in the RMC sentence ( or the position message form seatalk) and sends a !GPWPL message to the laptop
I dont send other ais
messages. The mmsi number that appears is 199397788.
Must be a sort of deault number. Which is fine by me.
but how can a send a valid mmsi? All zeros would me more clear. This must be a different message. And how is it clear that this number is locked to this wpl message?
As opencpn shows it, there must be a way...
