Many times when I'm configuring the settings of the plane next to me, the my touch pad on the laptop just completely goes crazy. It skips and starts left clicking or right clicking without me clicking or doesn't click when i click. Or it starts going random directions.
This also happens on some Dell desktops with wired mouses, where the mouse does the same irratic behavior. Is it just Xbee RF interference? Is there anything to prevent this?
This is caused by windows misinterpreting the driver for XBee. It's happened to me on Windows XP, not sure about windows 7 as my field notebook is only XP. There is no proper fix for it. The only work around I have found is as follows:
That will fix the problem for now. It appears to happen randomly so there is no guarantee that it won't happen again.
Hope that helps.
I had a similar problem in windows 7, but my mouse would jump around. XBee TM module showed up as Microsoft Serial BallPoint in device manager. Luckily my mouse still kinda worked, so I could just disable it and was good to go.
Just keep your virtual comport busy before you power the APM, keep it opened by an application (MP/GCS/etc). Otherwise, when APM is sending telemetry data windows thinks there is a "Microsoft Serial BallPoint" connected to the comport.
So start Mission Planner before powering up the APM?
