Re: Broadcom Corp. BCM20702A0 Bluetooth 4.0: connection to Apple Trackpad

I searched the https://bugs.archlinux.org/ and I found nothing about this bug.

I found this about the error "Can't get HIDP connection info": https://github.com/bluez/bluez/issues/76

Re: Broadcom Corp. BCM20702A0 Bluetooth 4.0: connection to Apple Trackpad

Same error after downgrade from "linux 5.15.13.arch1-1" to "5.15.12-arch1-1":

$ uname --all
Linux stephane-arch-desktop 5.15.12-arch1-1 #1 SMP PREEMPT Wed, 29 Dec 2021 12:04:56 +0000 x86_64 GNU/Linux
┌[stephane☮stephane-arch-desktop]-(~)
$ pacman -Q bluez
bluez 5.63-1

Note: I have downgraded the kernel package with this command:

$ sudo pacman -U /var/cache/pacman/pkg/linux-5.15.12.arch1-1-x86_64.pkg.tar.zst
$ sudo reboot

Re: Broadcom Corp. BCM20702A0 Bluetooth 4.0: connection to Apple Trackpad

No issue on Fedora 35 on same hardware, I connected Apple trackpad in bluetooth with success.

This is version detail:

I searched the https://bugs.archlinux.org/ and I found nothing about this bug.

I found this about the error "Can't get HIDP connection info": https://github.com/bluez/bluez/issues/76

This message is coming from: https://github.com/bluez/bluez/blob/mas … ice.c#L880. ioctl, so this is a kernel issue most likely.
