Public bug reported:
Laptop: Dell Inspiron 7370
CID: 201704-25503
Ubuntu version: 20.04 daily
Linux kernel: 5.4.0-18-generic
Bluez: 5.53-0ubuntu2
Summary
=======
BT earphones/speaker cannot be connected either using GNOME control
center, either using bluetoothctl. I've tried with previous versions of
the kernel as well (5.4.0-14, 5.4.0-9) and it exhibits the same issue,
so I believe this is a problem with bluez.
However, the same procedure works fine on Ubuntu 19.10 (kernel 5.3.0-18,
bluez 5.50), so I think it's a regression in bluez.
Steps to reproduce
==================
1. Open GNOME control center, go to Bluetooth, make sure it's turned on
2. Put the BT device in pairing mode (usually, long press on the Power button)
-> in g-c-c, the device appears as "Not Set Up" (OK)
3. Click on the device to pair it
-> the device is briefly marked as "Connected", then immediately switches to
"Disconnected" (Not OK)
The attached btmon logs (5.4.0-18-btmon-speaker.log) show what happens
when I follow steps 1-3 above.
I tried the same procedure on a 19.10 live usb (kernel 5.3.0-18, bluez
5.50) and it works fine (see attached logs 5.3.0-18-btmon-speaker.log)
Back to Ubuntu 20.04, if I try to pair and connect the device using
bluetoothctl, it fails:
$ sudo bluetoothctl
