Bluetooth keeps disconnecting. I am on 20.04 with kernel 5.6.3. Pairing is very unstable if I want to pair my mx keys keyboard it works only when I disconnect all bluetooth devices including my mx master 3 and than pair the desired device only. After that enabling my devices keyboard and mouse works but as said the keyboard disconnects and sometimes replicates a key stroke multiple times.
Also bluetooth headset does not work. It connects (same as above) but plays only weird cracking sound. dmesg | grep Blue [ 3.146254] Bluetooth: Core ver 2.22 [ 3.146265] Bluetooth: HCI device and connection manager initialized [ 3.146268] Bluetooth: HCI socket layer initialized [ 3.146269] Bluetooth: L2CAP socket layer initialized [ 3.146271] Bluetooth: SCO socket layer initialized [ 3.151323] Bluetooth: hci0: Bootloader revision 0.3 build 0 week 24 2017 [ 3.152333] Bluetooth: hci0: Device revision is 1 [ 3.152334] Bluetooth: hci0: Secure boot is enabled [ 3.152334] Bluetooth: hci0: OTP lock is enabled [ 3.152335] Bluetooth: hci0: API lock is enabled [ 3.152335] Bluetooth: hci0: Debug lock is disabled [ 3.152336] Bluetooth: hci0: Minimum firmware build 1 week 10 2014 [ 3.153088] Bluetooth: hci0: Found device firmware: intel/ibt-20-1-3.sfi [ 4.649137] Bluetooth: hci0: Waiting for firmware download to complete [ 4.649303] Bluetooth: hci0: Firmware loaded in 1463906 usecs [ 4.649330] Bluetooth: hci0: Waiting for device to boot [ 4.663324] Bluetooth: hci0: Device booted in 13671 usecs [ 4.666107] Bluetooth: hci0: Found Intel DDC parameters: intel/ibt-20-1-3.ddc [ 4.666330] Bluetooth: hci0: Failed to send Intel_Write_DDC (-22) [ 4.668309] Bluetooth: hci0: Firmware revision 0.0 build 128 week 11 2020 [ 5.357694] Bluetooth: BNEP (Ethernet Emulation) ver 1.3 [ 5.357695] Bluetooth: BNEP filters: protocol multicast [ 5.357698] Bluetooth: BNEP socket layer initialized [ 25.972964] Bluetooth: RFCOMM TTY layer initialized [ 25.972969] Bluetooth: RFCOMM socket layer initialized [ 25.972972] Bluetooth: RFCOMM ver 1.11 [ 4639.734854] Bluetooth: hci0: command 0x0402 tx timeout [ 4641.750537] Bluetooth: hci0: command 0x2042 tx timeout Should I open another bug report for this?
