I recently got a RTK Here V2+ module. Long story short, the RTK feature works but the magnetometer is not detected. Until I replaced APM GPS with RTK I had two compasses working (internal and external). Now only internal is detected. I need the external compass to work, in my TradHeli Pixhawk is in a very noisy location.
Well, it doesn’t show in HW ID page. I confirmed that moving Here V2 unit doesn’t change the magnetometer readings. The detected one is the internal Pixhawk magnetometer. Shouldn’t there be more detected devices apart from the compass?
