"You can't do a compassmot or cal if you don't have telemetr . The compassmot instructions state to power with lipo via power module and to plug USB in. I don't have pixhawk but have never had an issue with APM or microbrai ."

" @Johnatan  Data encryption has been implementedas an option. now from server side you cannot tell what navigation data is being communicated between Drones & GCS. Also Telemetry data is encrypted. "

"@Oscar Thanks :) Well it depends on what part of Andruav do you want to use. For a telemetry you need an Android 4+  to allow a USB Host.  if you want to have IMU data without the board using the FPV button then you need a mobile with gyro…"
