Nope. My iPad mini 4 is practically unusable.
As a sanity check, make sure your iPad WiFi is turned off when flying, or try flying the P4P on the 5.8Ghz band. The iPad, with Wifi turned ON, can hunt for an access point, pinging every WiFi channel on 2.4Ghz. This will interfere with the 2.4Ghz video downlink from the craft. This results in a broken up green screen image, regardless of the distance between the RC and craft. Usually the iPad WiFi searches only the 2.4Ghz band, so alternatively if you fly on the 5.8Ghz band with the P4P, this can alleviate this kind of interference too, even with iPad WiFi on..same here mini4 unusable when update into ios11
This is from the evidence. When this happened last weekend, flying on 5.8 worked fine with the iPad Wifi on. But flying 2.4Ghz resulted in garbled video. However when we turned off the iPad WiFi, the video feed worked fine. With that evidence I concluded the iPad doesn't scan 5.8Ghz. This may be a wrong conclusion as the evidence points, as you point out, but there is no interference when flying 5.8Ghz with iPad Wifi on.I disagree John. It is off. Also how do you make the assumption that it’s actively hunting every channel on 2.4Ghz.
If you read my post, it starts off with "As a sanity check". I'm not saying it will solve everyone's problem. But the iPad Mini4 we used last weekend with iOS11 worked fine with GO4 flying a P4P. I personally don't believe there's a problem with Go4 or the iPad Mini4 not having enough performance. However we did have a problem with the iPad Mini4 when the WiFi was ON. I'm only sharing our experience. If you don't want to believe our findings, that's fine, you don't have to, but they are real.The other thing as this problem goes away when I use an iPhone 7 Plus or iPhone X. It’s simple: the processors in the mini line cannot handle the amount of live feed data being shoved into the iPad. Reducing the feeds bitrate mostly solves the issue.
I think your iPad Mini4 will work with iOS11 and the latest GO4. I've seen it work. Have you tried my sanity check?I’ll just say this because I’m in the middle of a huge battle with them and font have a resolution yet: after they replaced ALL my equipment, it failed out of the box with my iPad mini 4. But my iPhone worked.
