Bluetooth borked after 16.04 upgrade

[Evil Wayz]

Another way is to

echo mt7601u | sudo tee -a /etc/modules

I tried that and it showed it was there, but it didn't work until I did this:

sudo modprobe mt7601u && dmesg | grep mt76

I notice it says there's an eeprom error?

[ 1418.406905] mt7601u 5-2.4.1:1.0: Warning: unsupported EEPROM version 0d
[ 1418.406913] mt7601u 5-2.4.1:1.0: EEPROM ver:0d fae:00

I wonder if that module is blacklisted somewhere?

There are some module parameters for bluetooth and btusb. You can see them with

modinfo -p btusb
modinfo -p bluetooth

If you have set module parameters before just try the one that mention SCO

I'm not sure I know what you want me to do so here's the output of that:

wolf@shaitan:~$ modinfo -p btusb
disable_scofix:Disable fixup of wrong SCO buffer size (bool)
force_scofix:Force fixup of wrong SCO buffers size (bool)
reset:Send HCI reset command on initialization (bool)
wolf@shaitan:~$ modinfo -p bluetooth
disable_esco:Disable eSCO connection creation (bool)
disable_ertm:Disable enhanced retransmission mode (bool)

[jeremy31]

A few things we can try with either bluetooth dongle since they have the same issue.

sudo modprobe -r btusb
sudo modprobe btusb disable_scofix=Y

Try using bluetooth for a while and see if the SCO messages are in the dmesg log

And to see if you wireless module is blacklisted

grep [[:alnum:]] /etc/modprobe.d/* | grep mt7601u

I don't know how to do that.

And to see if you wireless module is blacklisted

grep [[:alnum:]] /etc/modprobe.d/* | grep mt7601u

OOUtput:

wolf@shaitan:~$ grep [[:alnum:]] /etc/modprobe.d/* | grep mt7601u
/etc/modprobe.d/blacklist-mt7601u.conf:blacklist mt7601u
wolf@shaitan:~$

Is it blacklisted? Because when I woke up this morning it had connected to my router on it's own.

[jeremy31]

sudo rm /etc/modprobe.d/blacklist-mt7601u.conf

The module should load on its own

And you can check for bluetooth errors

dmesg | grep -i bluetooth

[Evil Wayz]

Ok this is the log, what am I looking for in here?

I don't see any SCO errors anymore. Does the bluetooth keyboard work properly?

[Evil Wayz]

I don't see any SCO errors anymore. Does the bluetooth keyboard work properly?

Both headphones connect, but they no longer say "connected" i Have to go into bluetooth or sound settings to confirm. The keyboard also connects, but the little battery status icon no longer appears in the panel. Also, I STILL don't have a bluetooth indicator on my panel when bluetooth is enabled and visible. But It works, so I'll take it. I probably should have waited for the point release, but I've never stuck with the LTS version before, I used to upgrade everytime a new release came out.

Hey, is there a way I can disable HSP/HFP or force AD2P? Every now and again the headset wants to connect as a headset, and when I try to switch it it goes back to speakers. I have to open and close the sound dialog box for it to decide to work.

[jeremy31]

The battery and bluetooth icons missing might be a cinnamon bug

I haven't found a way to disable HSP/HFP in 16.04 yet but I haven't installed pavucontrol, a pulse audio control package either

And if the change above helped

echo "options btusb disable_scofix=Y" | sudo tee /etc/modprobe.d/btusb.conf

That way you won't have to

sudo modprobe -r btusb
sudo modprobe btusb disable_scofix=Y

After every reboot
