I try to run the examples with video detections, like Bullfight or Color Detection. But it does not show the video stream. it says IP adress of Picar-x 192.168.xx.xxx connection refused. But I can take pictures on the pi via ssh and they look good. Connection: WiFi Image: Raspios-buster-armhf-lite-2021-1-11\_EzBlockOS-v1.2.3 Raspberrd Pi zero 2 W When trying to use the iOS App on my iPad Air, it shows a white screen at the video widget. But the app only connects with Bluetooth, no option to do it via WiFi. Any suggestions? ---

1.What version of the iPad Air do you have, and what is the system version? Please let us know so that we can replicate and resolve the issue. 2.We recommend recording a video of the process for us to help you analyze and solve the problem.

As I wrote i my answer, iPad Air 5. Generation. But the main problem is the web version on laptop. And I simply start the bullfight and get this view on the video widget. There are no additioal steps involved that could be shown on a video. All examples without the camera work. ---

But I solved the problem by changing the Pi to a 4B. Now everything is working fine. Also the lag of the remote control is gone. Simple conclusion- Pi Zero is not a good choice But be aware, when changing the board, you have to reset the servos again, so you have to be careful. Better disassembling at least the tilt servo. It just turned a little bit on all servos ---

We recommend using the Raspberry Pi 5/4/3B+/3B/Zero 2W. Raspberry Pi 4 is the best choice.
