LIS3MDL Pixhawk can not see the compass

I bought a DROTEK GPS with LIS3MDL compass.
My Pixhawk 2.4.8 does not see the compass LIS3MDL.
When I connect a GPS Radiolink SE100 it sees a compass
I am using a 3.4.1 rover firmware
I tested on the latest copter 3.5.5 firmware and it does not work
The GPS module is damaged?
What to do?
I will add that the GPS works properly
