I have a little quad setup for doing tests on various flight controllers, FPV etc. Went out to try out a new FPV camera using APM 2.5+ with Ublox GPS (both from 3DR). Had been working fine (about a month old) but today when I went to fly from same location as I have been, I get no GPS lock - or any indication that I have picked up any satellites (no gps path lines on MP). When I tried to fly in stabilize mode, the quad went pretty wacky - started yawing pretty quickly. Went back and did radio calibration and throttle/esc calibration. I have compass on auto (1). Still no sign of any satellites locking. Any ideas? Only change I have done is I updated MP a couple of days ago. Otherwise, everythng is the same. Running V2.9.1b ?????
