For simulation of GPS
, I send NMEA
sentences on TCP.
I'm running OCPN Beta Version 3.1.1319
!AIVDM messages work fine and the simulated ships are displayed.
messages never move the boat to the specified position.
They are received by OpenCPN
and visible in the activated NMEA
Display Window, for example :
14:35:01 [TCP:localhost:2947] $GPGGA,123519,4807.038,N,01131.000,E,1,08,0.9,545. 4,M,46.9,M,,*47
I tried different GGA and GLL sentences with the same result and I don't see what is wrong.
Grateful for any explanation
