Bluetooth Locking Up

Thu Apr 05, 2018 5:45 pm

We have built an application that uses the BV6000 Bluetooth to monitor BLE beacons with help locate the User as well as identify specific smart wearable sensors. The challenge is the BT stops scanning at varied intervals and we have had to write a program to recognize this and turn off BT and turn it back on which is a work around. We have 120 devices and they all are having this behavior. We have numerous other devices that we are testing as well and they do not have this issue. Is there a process that is turning off BT based on some variable?

Consider this simple tutorial:

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  ;)

Unfortunately, this did not resolve the issue.
