Bluetooth Connectivity Issue on Keychron K2 Keyboard

Support
1

Hi, I’m having problem with my Keychron K2 Keyboard when connecting to my laptop via Bluetooth. At first, it will connect successfully but after a reboot or if my keyboard were inactive for some time, it will no longer reconnect to my laptop. Notification keeps popping-up, saying “Connected” then “Disconnected” instantly and it happens again and again. And in bluetooth-manager it says Connection Failed: br-connection-create-socket

So I always have to “remove” then “re-pair” my keyboard again using the bluetooth-manager just to connect my keyboard again. I’ve found similar issue on reddit saying

"I’ve managed to fix it, the hid-Apple module wasn’t loaded in my custom kernel"

However, it’s not clear to me how to “load” the hid-Apple module and I am not sure if this solution will work to me as well, but might as well try. Appreciate the help. Thanks!

Before that, check if it’s loaded in the first place:

$ lsmod | grep hid_apple

if there’s no output, it’s not loaded. Then you can issue:

$ sudo modprobe -v hid_apple

Keychron keyboards do use hid_apple module to work on Linux.

Hi! Thanks for the quick reply. I’ve tried lsmod | grep hid_apple and no output. Then I tried sudo modprobe -v hid_apple and it shows hid_apple 20480 0 I tried to reboot first then reproduce the issue again (connect kb to bluetooth > disconnect > reconnect again). Unfortunately, the same issue still persist and my kb still don’t reconnect automatically.

After installing kernel version 5.19.14-1-MANJARO the problem seems to be fixed. My keyboard connects and reconnects successfully now either after reboot or if my keyboard wakes up from sleep-mode.
