I bought a second hand Pixhawk controller and ordered a NEO-7M from RCTimer.
I had to change the 5 pin to the 6 pin plug with the ground at pin 6. When I power on the unit it gives a quick flash of he green LED on the gps and MP shows "NO GPS".
I checked power on the PixHawk GPS port and I have 5.2v between pins 1 and 6. Opened up GPS and power is present there as well.
Is there a parameter that I need to change to enable this GPS?
