Bluetooth adapter is crashing when connecting keyboard or scanning

Post by Dibo » Sun Dec 17, 2017 10:16 am

Hi,

Around half year ago I bought bluetooth keyboard. It worked perfect, used it few weeks. Then switched on USB keyboard for a months. Now I want to back to this bluetooth keyboard but when connect it I can write only few words and my bluetooth adapter is crashing. Can't turn it on. Only reboot help but it crash again when try to connect. Tried also remove keyboard from known devices and add it againg but adapter is crashing in the middle of searching for devices. Sometimes it find devices but crash again in the middle of connecting with keyboard. Note that I'm able to turn off and turn on bluetooth few times from KDE tray menu but after 2-3 tries there is a permament crash and nothing can up adapter, only system reboot. I remember that some time ago I saw bluetooth update in one of my actualizations, so maybe there is a problem with new driver or something.
Here are some results of my hiconfig command line:

Code: Select all

~ $ hciconfig -a

Attached also screens from bluetooth settings where it complains that my adapter is not on, click on "change it" do nothing, adapter is still down

Tried now

Code: Select all

sudo apt-get install --reinstall bluez
and reboot OS. Same things, never ending scanning, had to turn off and turn on bluetooth few times and it finally found devices around, I was even able to connect to my keyboard but few words and led on keyboard start blinking and scan command hanging again. Probably few bluetooth restarts more and it crash permamently again
