Hi Guys,
Yesterday I had a bad Levo day as the bike didn't want to connect with the BV6000 with Android 7.0 anymore. Believe me I have tried everything. Strange thing was that both MC and BLEvo were not able to connect anymore. I also switched the phone back to factory settings. Really nothing helped.
In the end I tried to connect the bike to my iphone where both the ios MC and BLEvo app gave instant and stable connection. Then I remembered I have an old Samsung Tablet. I installed MC and BLEvo on the Samsung Tablet which is running on Android 5.0.2. Also there the connection was stable and instant.
Still had the issue with the BV6000 connection. Then I started to Google around and I found this post:
Bluetooth (and apps using it) will degrade their playback performance if battery saver option is enabled. This is due to an aggressive battery policy made by google, as this problem is not only present in blackview smartphones but also in google's ones!
You must disable the battery optimization optionfor the bluetooth services and for every app that will use bluetooth to transmit data (spotify, music player, and so on...) After that, your bluetooth performance will be perfect.
How to?
1) Go to settings -> Battery
2) Tap on the "3 dots" in the upper right corner of the app
3) Tap on "Battery optimization"
4) Select "All apps" from the drop down menu
5) Tap on the desired app and select "Don't optimize"
As i wrote before, you have to disable battery optimization for every bluetooth service (Bluetooth MIDI service, BT Tool, Bluetooth sharing) and for every app that will use bluetooth to transmit data (your music player, Call manager, telephone dialer app and so on). You will find everything in the "All apps" list in the Battery optimization settings.
I tried the settings above on the BV6000 for both the MC and BLEvo app. Guess what, connection is stable and instant again. As an ios user I am still amazed about all these hidden Android settings. The devil seems to be in the details...
I hope this post can help others too. Please let us know too if it has helped then I know also for sure this must have been the issue. I know there were many people with MC and BLEvo connection issues with the new 2019 Levo.
