Title:
UT does not discover bluetooth smart (BLE) devices
Status in indicator-bluetooth package in Ubuntu:
New
Bug description:
Same as https://bugs.launchpad.net/ubuntu/+source/ubuntu-system-
settings/+bug/1576986 but I thought I'd also post it here.
I am actually typing this on a Microsoft Universal Foldable Keyboard
connected to my M10 tablet.
Device: Bq Aquaris M10
OS: OTA-10.1
Generally bluetooth devices that are not version 4 or bluetooth smart
(BLE) seem to work and pair fine with the Aquaris E4.5 and the M10.
However, when it comes to BLE/version 4, things obviously get too
complicated for the system bluetooth settings because it doesn't even
manage to discover these devices.
OTA-10.1 uses Bluez version 5.37, which is perfectly capable of
discovering and pairing with BLE devices, but in Ubuntu Touch it
requires the use of "bluetoothctl" in the terminal. I will describe
the steps needed below:
phablet@ubuntu-phablet:-$ bluetoothctl
[bluetooth]# scan on
wait for device to show up in list, typically:
[NEW] Device 01:02:FF:A8:BB:00 DeviceName
[bluetooth]# discoverable on
Changing discoverable on succeeded
[bluetooth]# agent on
Agent registered
[bluetooth]# default-agent
Default agent request successful
[bluetooth]# pairable on
Changing pairable on succeeded
Now tell bluetoothctl to pair the device
[bluetooth]# pair 01:02:FF:A8:BB:00
Attempting to pair with 01:02:FF:A8:BB:00
If pairing with MS Universal Foldable Keyboard, you will probably see
a 6-digit code, punch that code on the keyboard and hit return.
[CHG] Device 01:02:FF:A8:BB:00 Connected: yes
[agent] Passkey: 123456
You should be good to go.
However, the MS Foldable Keyboard does not show up in system bluetooth
settings (see attached screenshot) and getting the M10 to recognize
that the Keyboard is turned off seems to require a reboot (and
possibly also bluetooth turned off). Otherwise, the onscreen keyboard
doesn't show up.
