It can connect to my wireless AA, but it only stays at the Bluetooth connection stage. How can this be solved?

1. Open [Settings]

Select [Apps]

In the app list, find and open [Google / Google Play services]

Tap [Storage & cache]

Select [Clear cache]. ‼️Do not tap Clear data, as this will log you out of your account.

Then restart the phone. 2. Submit the log and video: while the device is powered on, please manually join the adapter's WiFi network [AdapterMX-xxxx]; the password is 88888888. Next, enter 192.168.1.101 in the iPhone browser, access the backend and submit the log. And send a video to customer service
