After PosHold and RTL I wanted to fly a mission and found that QGC is not ready yet.
I bought a Toshiba tablet AT200 and a BT module. I connected the BT module to my XBee Pro 900 with USB breakoutboard. A "homesoldered" USB cable mini male to micro male OTG () made the trick to receive power from the tablet. But the modules can also be powered from a laptop with a normal USB A to mini cable.
The Android AQGC 1.5.8 works flawless with AQ 6.6 R19. Missions can be saved to AQ and retrieved. If there would be an "issue" thread I (and others) could post their findings.
Can't wait to fly my first mission and try "Orbit".
Thanks for the fine software.
Best
