Bluetooth on 3.19.0 (Ubuntu 15.04) #7

Open sergeyksv opened 9 years ago

sergeyksv commented 9 years ago

Sorry to bother you, just upgraded to subject and bluetooth stops working. Any clue how I can troubleshoot it. What to check etc. Nothing unusual in dmesg.

kuba-moo commented 9 years ago

TBH I know very little about BT stack. Does your system see the device but it doesn't work or is there no device at all? Did you try loading the BT module (mt76xx) manually? As far as I understand BT module just switches the device into appropriate mode and then it is handled by the generic btusb driver so we would have to find out at which stage things fail to solve this.

sergeyksv commented 9 years ago

Initially I just used your make file, and everything works. Later I update to 15.04 and it stop working and I didn't change anything. I tried to reinstall driver manually nothing changes. I believe that probably this is somehow related to hardware (asus laptop) disabling of blluetooth radio. Initially after boot I didn't see now any mentions about mediatek bluetooth. But if to suspend laptop and then bring it back I see following in dmesg:

[   30.980106] usb 1-5: new high-speed USB device number 6 using xhci_hcd
[   31.109644] usb 1-5: New USB device found, idVendor=0e8d, idProduct=763f

[   31.109648] usb 1-5: Manufacturer: MediaTek
[   31.109649] usb 1-5: SerialNumber: 1.0

However this still didn't make it working. This symptom is sound very similar to this: http://ubuntuforums.org/showthread.php?t=2181558

However wi-fi work fine.

kuba-moo commented 9 years ago

Please try rfkill list command to see if the device is indeed blocked.

sergeyksv commented 9 years ago

device is not blocked. I noticed another thing. Now if I do "modprobe mt76xx" as see messages in dmesg that "usbcore: registered new interface driver mtk_bt_loader". So it didn't loaded after boot?

After then if to suspend/unsuspend laptop I see this:

Same problem on my machine running Ubuntu 15.10 with kernel 4.2.0-17-generic, wifi is ok but bluetooth is not working. Don't know if this may help, but in my configuration the problem seems to be the HCI device initialization. The device is identified as hci0:

$ hciconfig hci0 -a
hci0:   Type: BR/EDR  Bus: USB
    BD Address: 54:35:30:56:92:56  ACL MTU: 1021:4  SCO MTU: 128:2

    Packet type: DM1 DM3 DM5 DH1 DH3 DH5 HV1 HV2 HV3 
    Link policy: RSWITCH HOLD SNIFF PARK 
    Link mode: SLAVE ACCEPT

When trying to bring it up, I get this error:

$ sudo hciconfig hci0 up
Can't init device hci0: Invalid request code (56)

Using btmon to trace HCI commands, it seems that the error is caused by an unsupported HCI command (Read Local Supported Codecs to which the device responds with Unknown HCI Command). Here's the output of btmon:

Hope it helps to identify the problem.

Well for me the error isn't exactly the same:

$ hciconfig hci0 -a
Can't get device info: No such device

And the dmesg spam me (every second) with:

@sonvirgo : You should try to read this: https://github.com/neurobin/MT7630E/issues/6#issuecomment-196090923

@tobiasBora you mean rebuild kernel? I can't afford it. Thank you any way.

tobiasBora commented 8 years ago

Well you build only a part of the kernel (it takes only a few seconds) and then replace only a single file. It's not that heavy.
