NMEA message not recognized by agriculture machine

Hi @mxnofear,

Reach outputs GNGGA.
If you need to change GN string from Reach to GP, the only thing I can recommend you is to output the position from Reach on 3rd-party board (Arduino or RPi), write a script that changes strings, and run it on this board.

You should set up the update rate in RTK settings to 5 Hz.
