Well this seems odd to me and no idea what to do.
I have 3DR Quad about a year old - I haven't been able to do anything with it for awhile and just getting back to it now. APM 2.6. I have a new receiver and Taranis FRSKY radio so getting everything hooked up.
I know gps was working in March because I did work on the copter for a bit and tested it then but didn't get any further.
There is power to GPS (Solid Red Light) but no lock showing on GPS. I am getting flashing blue light so looks like GPS is powered up properly. I tried loading the latest firmware 3.5.1 but that has not helped.
Not sure where to go from here so any idea would be quite welcome.
