What is your problem?

I used Honor Play to connect to my Bluetooth device. After successfully connecting for the first time, I disconnected the Bluetooth connection. Then, I had the Bluetooth device emit a Bluetooth broadcast, and when I tried to connect to the Bluetooth device again, I couldn't connect. The specific reason for the error, as shown in the log, was due to a connection timeout. However, I couldn't reproduce this issue when using other Android phones, which is a mandatory issue on Honor Play

increase the timeout to 90 seconds

Thanks，After setting the time to 90 seconds, I still couldn't connect successfully, but another Android 133 error was reported. Then I searched for relevant issues and added a 300ms delay to the Bluetooth of the device on my phone before connecting again, and it was successful！
