I have a Logitech k480 keyboard that I can switch between three devices using bluetooth. When I use it on a windows computer it works great, ditto with my Samsung tablet. But with Raspberry Pi 4 Manjaro I am able to pair and connect without issue, but I get repeating keys.
I had a period of time before the kernel upgrade in November (?) where it worked fine, so I suspect that.
I need to do more testing on Raspberry Pi OS because I think that would help. I’ll do that next, but if you have any other tips beyond remove and re-pair I’d appreciate it.
No clue where to start. What I do know is the kernel config is the exact same as theirs with some extra modules added. The bluetooth firmware is the same and most likely their package versions are older.
That is a really old kernel and really should not be installed. The current -rc I pushed to the unstable branch a couple of days ago which is linux-rpi4-rc 5.11-rc2 I believe if you want to try it. Remember although I have had no issues the -rc kernels are a work in progress.
I’m using 5.11.0-rc2-1-MANJARO-ARM now. It repeats keys although not to the same extrreme that thhhhhhe ccurrennnnnnntt kernel does. (an example there before I switched back to a non-BT keyboard). The BT Keyboard response is delayed too–it delays and then repeats.
