I have the M5 8.4" and it works perfectly, having used it with my Air1 and now my
Mini 2. Not too sure about the compass part of it though as I have never needed this facility as I always keep an eye on where my drone is relative to home point and if I can't pinpoint it accurately I just initiate RTH until in sight then pick up where I left off. Brilliant tablet and in my opinion so much better value than Apple and I personally hate the wy Apple locks everything down and their security measures are a joke as is their file system and saving stuff to the cloud. Give me Windows and Android any day. Must add this is my personal opinion and I realise that there are millions of people who love Apple products. Buy Huawei and you won't go wrong.
