So I have a pixhawk powered Octocopter and I make sure that I am connected to MP every flight mostly for gps record keeping, and being able to use guided mode.
When I click connect it freezes everything on the laptop for about 1 minute. Then it will start to connect and it takes at least another minute to go through all the inputs.
If I connect over USB, it still takes about a minute for the dialog box to come up but at least it will connect quickly after that.
It wasn’t this slow when I first started using pixhawk/Mission planner back in January.
Computer is running windows 8 64 bit. Connecting via a genuine 3DR telemetry.
