I want to use the COG generated by my easyTRX2-IS and have it on a display. I therefore connected the easyTRX to a multiplexer. It receive the following sentences at the multiplexer: AIVDM, GPGGA, GPGLL and GPRMC. What I miss is the GPVTG sentence and that’s the one I need. According to the manual it should be there, but I don’t see it. Any idea where to look or what to check?
