Hi there, I have some problems to get my GPS with compass running:

This is this model

I know I order the GPS Module for CC3D but I want install it on my APM Mini 3.1, is there differents hardware or protocols? I guess it's just the wiring that changes? No ?

I have re-wired it cause it comes with four wires only, SD and SC were missing, GND, 5V, SD, SC, RX, TX, are all connected to my APM MINI 3.1.

The GPS module has the led flashing blue at 1Hz, according to my research that means a GPS fix.

Now I don't know if I have to set up something in APM Planner (2.0.20 Mac) because the Flight data info window shows no GPS data, compass calibration fail.

Thanks in advance for your help.
