Bluetooth shutting down intermittently

Mon Apr 16, 2018 7:27 pm

We have 100 BV6000 devices and all of them exhibit the same behavior. The Bluetooth stops scanning for no apparent reason. We have spent numerous hours isolating the issue and have determined it is the BV6000 firmware. We are running BV6000_Blackview_V01_20170412 with the kernel version 3.18.35 Fri Mar 30 15:22:38 CST 2018 on a few to see if the latest patch would resolve the issue and it has not. We are wanting to standardize on this device for large enterprise deployments and this is an issue that will keep us from moving forward. Please contact us as soon as possible.

I suggest to try this workaround made for the BV8000pro. It should work!

0) Consider updating your device to the latest firmware and performing a factory reset after that

1) Go to "Settings" -> "Background task clear" and whitelist all your 3rd party apps wich need bluetooth to transfer data (i.e. samsung gear app, veryfit app and so on..). By doing that, they will be allowed to run in background even if the smartphone is in deep sleep state.

2) Go to "Settings" -> "Battery" -> "3 dots" in the upper right corner -> "Battery optimization" -> select "All apps" from the dropdown menu and disable battery optimization for every bluetooth service app, as
- Bluetooth MIDI service
- BT Tool
- Bluetooth sharing

and for every app needing to use bluetooth to transmit data, as
- Phone
- Phone services
- Call management
- Phone/Messaging storage
- your 3rd party music player
- other telephone dialer apps
- fitness band apps and so on

3) Only if the previous steps doesn't solve your issue, ALSO:
- Go to "Settings" -> "Battery" and disable "Standby intelligent power saving"
- Go to "Settings" -> "Duraspeed" and and disable it.

4) Only if, again, the previous steps still don't solve your issue, ALSO go to "Settings" -> "Battery" and set your device into "High performance mode"

Please follow these steps carefully and report back if your bluetooth issue gets solved ;)
