New: Logitech K380 pairs but cannot connect
https://bugzilla.kernel.org/show_bug.cgi?id=208015
Bug ID: 208015
Summary: Logitech K380 pairs but cannot connect
Product: Drivers
Version: 2.5
Kernel Version: 5.6.14-300.fc32.x86_64
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Bluetooth
Assignee: [email protected]
Reporter: [email protected]
Regression: NoI have a logitech K380 which goes through the pair process, either from bluetoothctl or from the gnome bluetooth control panel, accepting the keystrokes for the pairing password, right up to the RETURN, and then the connection fails.
At that point, bluetoothctl shows it as paired, but it cannot connect. Touching a key on the keyboard to get it to try to connect shows this in btmon.

I regularly use this keyboard on my Windows10 laptop and my android tablet, and it works perfectly in those environments.
There have been times when somehow the keyboard and BlueZ seem to get into a happy state and the pairing and connection will work, and then the keyboard will connect successfully for several days of use,...and then it will disconnect spontaneously while I'm typing,...just *bam*,...keyboard is gone and now it cannot connect again.
I've not found any reliable way of getting it to connect. Just try pairing and connecting over and over and then after 100 tries or so it'll connect and work for a few days.
The Logitech K380 is a current shipping product, and I *love* this keyboard. I'm ready to dive in on this to get to the bottom of it, at least in terms of doing experiments and providing logs. I'm not a programmer.

[Bug 208015] Logitech K380 pairs but cannot connect
https://bugzilla.kernel.org/show_bug.cgi?id=208015
--- Comment #2 from Joseph Ervin ([email protected]) --- Interestingly, I pulled the USB bluetooth dongle and reinserted it, and then things worked on the next try. Here's the btmon output of a successful connection. Note, I unpaired the keyboard and tried pairing it again and it failed, and pulling the dongle didn't work, so I don't think that's really related, or a workaround.

[Bug 208015] Logitech K380 pairs but cannot connect
In reply to [email protected]https://bugzilla.kernel.org/show_bug.cgi?id=208015
--- Comment #3 from Joseph Ervin ([email protected]) ---
I did experimentation on this problem all afternoon, and I've come to the conclusion that the problem is with the keyboard. This keyboard has three buttons on it that allow it to be paired with three different devices. Presumably it has three MAC addresses (if that's what they're called with bluetooth).
You press and hold one of the three buttons to enable pairing for that MAC address. It's a great feature, but I think between pairing and unpairing and switching between its three virtual personalities (or MAC addresses), something got messed up. Looking at the btmon traces, I saw cases where the keyboard appeared to be speaking gibberish during pairing, with btmon reporting lots of "unknown" interpretations of capability structures.
I was using MAC #1 for my windows laptop, MAC #2 for my android tablet, and MAC #3 for the linux box with the Broadcom USB BT adapter. Anyway, I turned off the Windows laptop, unpaired the keyboard from the Android tablet and then turned off bluetooth entirely on the android tablet. In that state, I was able to pair and unpair the keyboard using to the Linux box over and over with no problems. Then I re-enabled and repaired the keyboard on MAC #2 with the android tablet, and now all is well, and I can switch back and forth between them.
I'm closing this bug.
