RTK Handheld Surveyor Kit from ArduSimple. Survey and map with RTK and centimetre level accuracy!

Good evening gentlemen of Ardusimple.
I would like you to investigate what configuration is needed for the Ardusimple boards to work with the Survey Master APP. Several "Low Cost" GPS based on ZED F9P, can work with this application, but not Ardusimple boards. In my case, I have a SimpleRTK2B-V3 that connects perfectly via bluetooth to Survey Master, it also connects successfully to the NTRIP client of the application, but the corrections DO NOT arrive and it is always in "Standalone" or "Single". I would appreciate in advance any help you can provide in this case.
