Once you have paired your HUAWEI phone to a Bluetooth device (accessories, wearables), they should automatically reconnect if Bluetooth is enabled. If this is not happening, please follow the troubleshooting steps below.
A headset or a speaker doesn't reconnect automatically
If the headset or the speaker is too far away from the HUAWEI smartphone it was paired with, it will disconnect and exit the pairing mode and it won't automatically reconnect to your phone.
To solve this, open the Settings on your HUAWEI smartphone, search for the Build number and tap on it several times until the message 'You are now a developer!' is displayed; if prompted, enter the lock screen password.
Return to Settings, search for Bluetooth auto-connect and enable this feature.

Make sure that the other device is within the effective Bluetooth range from your smartphone and restart it.
Re-enable Bluetooth on the phone and check if the issue is fixed*. If the Bluetooth device still fails to reconnect, unpair it from your phone and then pair it again.
