Further to the problems I experienced with my touchpadthe problems I experienced with my touchpad, I am now encountering issues with bluetooth. Everything was working fine, but on my most recent reboot bluetooth now seems to have totally stopped working.
From my searching around various forums, a weird thing is that the output of
rfkill list all is only this:
0: phy0: Wireless LAN Soft blocked: no Hard blocked: no
lsmod | grep ath outputs:
ath3k 20480 0 ath9k 147456 0 ath9k_common 32768 1 ath9k ath9k_hw 479232 2 ath9k_common,ath9k ath 32768 3 ath9k_common,ath9k,ath9k_hw mac80211 753664 1 ath9k cfg80211 561152 5 wl,ath,ath9k_common,ath9k,mac80211 bluetooth 516096 14 bnep,ath3k,btbcm,btusb,rfcomm,btintel
bluetooth = none (no device)
But before the last reboot, it was working great. I had paired a keyboard and mouse. In System Settings, everything on the Bluetooth page is greyed out. I can't even try to turn it on and the device list is now blank.
Any thoughts or assistance much appreciated.
I'm feeling slightly closer, the output of
dmesg | grep -i blue is:
[ 3.925283] Bluetooth: Core ver 2.20 [ 3.925305] Bluetooth: HCI device and connection manager initialized [ 3.925309] Bluetooth: HCI socket layer initialized [ 3.925312] Bluetooth: L2CAP socket layer initialized [ 3.925318] Bluetooth: SCO socket layer initialized [ 3.946202] Bluetooth: BNEP (Ethernet Emulation) ver 1.3 [ 3.946205] Bluetooth: BNEP filters: protocol multicast [ 3.946209] Bluetooth: BNEP socket layer initialized [ 3.952299] Bluetooth: RFCOMM TTY layer initialized [ 3.952328] Bluetooth: RFCOMM socket layer initialized [ 3.952333] Bluetooth: RFCOMM ver 1.11 [ 5.271147] Bluetooth: Patch file not found ar3k/AthrBT_0x11020100.dfu [ 5.271149] Bluetooth: Loading patch file failed
It seems to be the same error as here, but a different bug causing it.
