me again
Just a question :
From what I read online, the Talker ID is here to help and differentiate from the NMEA trame which constallation was used to generate the Trame NMEA
But in my M2, in the RTK settings, I can select all , and can not uncheck GPS, which is look normal to me :
My question is, if I use GP or GN as talker ID, but I check GPS and Galileo in RTK settings, are the info from Galielo taken in consideration and computed to generate the NMEA or not at all ?
The talker ID for Galileo should be GA, but it is not possible to select it in the Position Output.
The talker code was originally intended for the NMEA bus of a ship. Because on the same NMEA bus you would have engine, hvac, cargo data and more all sharing the same data bus.
Dependant on the receiving hardware it can be picky about the talker code. Legacy systems parser code usually rejects GNGGA vs GPGGA data because it cannot decipher the GN.
Newer parsers look for GN not GP, some ignore the talker code regardless.
Talker code or ID has nothing to do with the individual constellations. Its to identify the data is coming from a gps or a gnss on a common nmea data bus.
