afro-coder opened this issue · comments
generic details:
kernel-4.4.0-36-generic
Linux mint 18 sarah.
wifi driver rtl8723be
bluetooth driver: rtl8723au
Things attached: Dmesg log, journalctl log, systemctl log.
Things that get the bluetooth device started are modprobe -rv btusb, modprobe -v btusb.
Module installed from kernel branch rest all throw errors.
boot-Config:: http://pastebin.com/6xnXMByS
Problem: I have installed rtlwifi .
My phone scans the laptop after updating bluez to the latest version, unable to pair/connect and hcitool scan fails.
After modprobe commands the bluetooth is visible for a rough 30 secs.
I've read all the issues on your kernel thread alspo still couldn't find a way to keep this stable
could you guide me on how to fix this.
I know you're very busy but a little help would be sufficient for me.
dmesg log and journalctl log

EDIT: after following this thread #39 I got the device up and running and stable but it doesn't find any devices but still this persists.
Edit1 : downgraded bluez to .23 Still can't find devices

@bajbijendra My wifi driver works fine Bluetooth on the other hand doesn't these above drivers are for wifi only
