I have an APM 2.6 running ArduCopter 3.2 RC6. For telemetry I'm using the 915MHz 3DR Telem module to talk to a Samsung Galaxy S3 running DroidPlanner. For my OSD I have a genuine DIYDrones MinimOSD V1.1 with the MinimOSD-extra 2.2 firmware.
When I boot up my quad the OSD shows zero satellites and 100% battery. Once I arm the copter, I can see my battery voltage, but it doesn't change as I fly.
If I connect my Galaxy S3 running DroidPlanner, the OSD fires up with data immediately once DroidPlanner connects.
