se hai due smartphone a disposizione prova questa procedura nata per la malefica cubo XIAOMI smart home camera 1080p:
Finally!!! I found the solution for CONNECTION TIMEDO OUT ISSUE after so much research.
NOTE:
1st: You need set the app to Mainland China. (Go to profile->Tap on Locale to change)
2nd: Use any extra mobile device to download Mi Home app
3rd: Use current phone with 4G to setup hotspot without password. - If you setup the hotspot with password, it will fail.
4th: Follow instruction to setup, when prompt for WiFi you need to select your "phone hotspot" and once scan QR code it will start loading and listen carefully if the speaker voice out twice it's for the WiFi set up successful and pair up successful. (If it voice out twice but connection failed, just re-try once and it will connect right away).
Lastly: once you done it just update cam firmware and then go back to use your current phone. Hold the setup button on camera and reset it. Then setup cam with house WiFi. NOTE: While entering the network credentials, dont go with saved passwords, TYPE THEM AGAIN. It saves invalid password.
Connection will be established immediately. If not try once more and it will connect.
No extra mobile phone needed anymore.
