@Pyradon,
What type of aircraft/vehicle do you have your flight controller in?
Are you using an APM or a Pixhawk.
If it is an APM, is it a 2.5 or a 2.6 and is it a clone or genuine 3DR?
Do you have both the GPS and the compass connected to your flight controller at the same time because the power for the compass comes from the GPS connection?
