I just did what you asked, and hey, everything seems to work just fine. That is, in the office, not in the field yet.
Mac mini with MacOS 10.15.2
QGC daily build
Xbox One bluetooth wireless controller
I had to change some of the buttons (I had „arm“ on 3 or 4 buttons), but now everything works like it did with the usb Logitech controller. Some buttons are a bit slow to work and I have to push twice (lights for example), but this is probably due to interference on the desktop (usb 3, wlan and bluetooth are acting up on my Mac mini). Also, the latency seems better, and QGC did not crash, when I closed the program (because I did not have the usb controller?). However, I am missing the audio and the „video on“ control on the main screen.
Can you recommend using the daily build version on my field laptop? So far I stuck with the latest stable version to minimize the crash risk in the field (never change a winning team). But the latest QGC and bluetooth support are quite a big step forward…
I will do a bit more testing in the Baltic soon and let you know how it goes. Thanks for keeping me up to date!!
