I am using the standard ACM 1280 with MediaTek GPS Module firmware 1.6.
I first build a Quad and uploaded at that time 2.0.39 firmware and both MTEK Blue LED and ACM red LED (C) were working fine when I get a GPS Lock.
Lately I finish building a new Tricopter Frame and I used the same equipment the only difference is I updated the firmware to (Arducopter V2.0.49 Beta Tri) firmware.
and this is what is happening with me in the field:
- The blue LED on the MediaTek module GPS is solid but the red APM GPS LED (C) is OFF.
- If I connect the APM with the (Mission Planner) MP though USB, I get both the Blue and Red LED solid and it shows 3D GPS lock on the MP, but if I disconnect the USB the Red LED goes OFF again and the Blue is solid.
I really appreciate any help and opinions
