[Bug 1531925] Re: Can't connect Logitech Living Room Keyboard [LE]


Ok, there seems to be another problem I didn't respected yet. Powering a
controller with hciconfig will bring it into a state where not all
subsystems are initialized required for LE support. We still have a udev
rule in our bluez package included which will try to power a bluetooth
controller via hciconfig which is really not what we should do as
described before. Starting with bluez 5.35/.36 there is a new option
bluez itself provides for this which defines a config element in
/etc/bluetooth/main.conf to do the same but the right way.

I am not sure if this udev rule comes into our way here but it feels a
bit like it does.

@Pat/Tony: Would be good if you can try the following:

sudo mount -o remount,rw /
sudo rm /lib/udev/rules.d/50-bluetooth-hci-auto-poweron.rules
echo "[Policy]" >> sudo tee -a /etc/bluetooth/main.conf
echo "AutoEnable=true" >> sudo tee -a /etc/bluetooth/main.conf

I've also pushed this change up at
detection as that is something we need to fix anyway.

If that doesn't help also try removing all bluetooth state information

sudo rm -rf /var/lib/bluetooth/*

and then reboot the device.

Bug description:
  Cannot connect a Logitech Illuminated Living Room keyboard to a device
  running bluez5.  There are two versions of the keyboard, a unifying
  receiver version, and a Bluetooth version.  The latter has a BT symbol
  on the 'del' key.  To put the BT version in pairing mode, power on the
  keyboard, then briefly hold the FN and 'del' key together and release.
  A green LED at the top right of the keyboard should start flashing

  Once in pairing mode, the device will become visible on desktop using
  the BT settings UI, however it's *never* shown in the UI on a device
  running the latest Touch ( OTA9.1+ ).  Note, this includes devices
  running a silo version of bluez 5.37, including both arale and
  krillin.  On both devices, the keyboard *is* viewable using

  It should be noted that LE keyboard support on touch should be a
  considered a missing feature.

  Here's the reported attributes of the device from my macair running
  15.10 + bluez 5.37:

  From bluetoothctl on both my laptop and my desktop, I'm able to pair,
  trust and connect the device, and info reflects these changes, however
  the device never actually connects, it's LED remains blinking fast,
  and the keyboard cannot be used.

  Note, before pairing, I issued the command 'agent KeyboardOnly' and
