This is an ALTERNATE solution for the Xiaomi Dafeng Camera (Ver. 5.5.1.200) to fix the connection timeout issue. If there is a newer version than the version in this video was made and the issue are fixed, will be removed.
(!) This solution is for Android devices (5.1 and higher) only. I don't have a solution for iOS yet.
(!) If the connection issue persist, please leave a comment which Brand and which version doesn't work. I can check with a emulator and try to give a solution for this specific device. You can submit the issue ans specify it clearly to: vdd-roger@outlook.com
Sorry for my bad English because I'm French :(
The subtitles may help you a little bit.
