Mini APM & LEA 6H GPS - not compatible?

Posted by ispresso on January 16, 2015 at 4:20pm

Hi,

I have a Mini APM and a 6H GPS 

I am pretty confident that I've got the wiring harness correct:

1) GPS has power

2)  GPS unit's compass is healthy, working (can calibrate it in mission planner)

3)  GPS has green light when it comes up, blinking blue after a little while (i believe this means GPS lock)

However in Mission Planner, it always shows "no gps".

Any ideas?

It seems the Mini APM is always sold with 6M GPS or M8N -- so maybe there is some compatibility issue?

Thanks

      It is hard to tell by the picture. Make sure you have tx from the gps going to rx on the apm and rx from the gps going to tx on the apm.

    Take a picture of the gps connector to the apm board. Maybe the tx and rx lines reversed
