Guys i have increased the altitude limit to 30 meters for Tello in the app but my Tello doesn't go beyond 15 meters no matter what i do. I even tried it on TelloFPV app but no success at all. Got myself a Xiaomi Wifi Repeater for better signal strength and signal did improve a lot but still it doesn't go beyond 15 meters. Surprisingly if i reduce the altitude limit to less than 15 meters it responds very well and when i try to play with altitude limit by either reducing or increasing the altitude Tello works fine but only till 15 metres. So in short any change to altitude limit works perfectly till 15 meters but nothing beyond that. Can any one help what could be the issue as i am feeling really disappointed and upset by the fact even a Wifi repeater didn't help in my case. I would request for some help and suggestions here. Mind you i am on the latest firmware already.
