When I got my lyzrc L900 pro se (the latest version of it, I had loads of trouble getting it to stay linked with my iPhone, and it kept dropping the wifi connection and reconnecting so it made it so what unusable, but after a bit of messing about I found that if I turned the iPhone to airplane mode and then connected to the drone it worked fine with a constant connection. This it seems is not a problem on Android phones so thank Apple for that one. Anyway the only problem I’ve been having is on my drone I have another sensor that fits on the top of the drone which is for the obstacle avoidance, unfortunately the only thing I can manage to do when it is connected is go up or down, any other direction is met with constant beeps. Anyone any ideas. I a complete newbie and so far have crashed it into a wall, got it stuck at the top of a tree and panicked like a girl when I tried the RTH button as it disappeared into the clouds, watching a tiny speck it did eventually come back, well sort of nearly, ( that was the tree) I have not touched that button since. I am hoping to find some really open ground with nothing around for miles )not much chance of that where I live) so I can try again. Last time I flew anything was when plastic spitfires with a glow plug engine on the end of a long string that went round and round until it either ran out of fuel or you fell over, think that was In the 60s so a drone is a very new experience for me, plus I’m now an old codger who should have grown out of it by now.
