my bluetooth mouse loses connection too easily

English Hardware

Hi,
I’m facing some issues with my bluetooth mouse, JETech 0884, that worked like a charm until yesterday (for 3 years). I’m running Leap 42.3 64bit and the pc has the motherboard Gigabyte ga-f2a88xn-wifi with an integrated bluetooth chip.

Usually when I log into the DE I only need to click the mouse button a couple of times so the mouse wakes up and automatically connects with the pc. On the plasma panel I can see the dots next the bluetooth icon so i know the connection succeed.

But since yesterday if I click the mouse’s buttons the dots next the bluetooth icon appear just for a fraction of second to disappear.

To connect the mouse I have to open the terminal, run

bluetoothctl

and then

connect "mac address"

while I press the connection button on the mouse.

So finally I can use the mouse.
The annoying thing it’s that if the mouse goes in sleep mode, after a period of inactivity, i have to do the same procedure and I can’t just wake the mouse by clicking its buttons.
Today i tried to uninstall and install bluedevil5 bluedevil5-lang bluez bluez-tools pulseaudio-module-bluetooth without success.

I wonder if TLP (Power Management Utility) might be helpful here. Although intended for laptop power management, it might be useful for bluetooth power management perhaps.

Specifically

         USB_BLACKLIST_BTUSB=1         
     Exclude bluetooth devices from autosuspend mode:
  • 0 – do not exclude
  • 1 – exclude
     Default when unconfigured: 0
     **Note:** this feature is intended to solve stability issues with bluetooth connections.
