Hi, we have bunch of HGLRC M100 Pro GPS modules. When we test, it was displaying 1050 meters for alt in the GPS_RAW_INT message. The real altitude is 1004 meters. With other GPS modules we tested, it is displayed correctly like in the GEPRC M10Q.
Also I checked other things, like alt_ellipsoid in the GPS_RAW_INT is reporting the same value as alt field unlike GEPRC and intended behavior.
It does not send status text like “HW: 000A000” but GEPRC does. It displays many satellites inside like 15 which we never saw with GEPRC.
We connected them to u-center 2 software it displays UBX-MON-VER message correctly same as GEPRC but it does not display most of the messages even we poll them manually like UBX-MON-RF and UBX-SEC-UNIQID which is strange.
I’m no GPS expert but something suspicious with those modules. And we tested like 5 of them and all same.
I already sent an email to support@hglrc.com 4 days ago and there’s no answer.
What can I do?
