Hi all,
Thinkpad X1 2015, ubuntu 15.10, the bluetooth module seems not work well.
Once connect, it prints the following kernel log:
[ 196.730943] Bluetooth: hci0 SCO packet for unknown connection handle 0
[ 196.730946] Bluetooth: hci0 SCO packet for unknown connection handle 0
[ 196.730948] Bluetooth: hci0 SCO packet for unknown connection handle 0
[ 196.740970] Bluetooth: hci0 SCO packet for unknown connection handle 0
[ 196.740975] Bluetooth: hci0 SCO packet for unknown connection handle 0
[ 196.740976] Bluetooth: hci0 SCO packet for unknown connection handle 0
[ 201.764755] Bluetooth: hci0 SCO packet for unknown connection handle 257
[ 201.764768] Bluetooth: hci0 SCO packet for unknown connection handle 257
[ 201.764777] Bluetooth: hci0 SCO packet for unknown connection handle 257
and something I think related while kernel initing:
[ 3.738275] usbcore: registered new interface driver btusb
[ 3.754215] Bluetooth: hci0: read Intel version: 370810011003110e00
[ 3.755429] Adding 7999996k swap on /swap/swapfile. Priority:-1
extents:66 across:13275644k SSFS
[ 3.757145] Bluetooth: hci0: Intel Bluetooth firmware file:
intel/ibt-hw-37.8.10-fw-1.10.3.11.e.bseq
I think it is a good chance for me to diving into the linux kernel, so
can anyone offer some hints that I could solve this problem.
$ uname -ar

Many thanks~
