I am trying without success to connect a Dell WM524 bluetooth mouse to my Arch system, a Dell XPS 13 2015 edition.
I am currently running GNOME with gnome-bluetooth, bluez, blueman, and blueman-utils installed and up to date. I have checked that Bluetooth is enabled.
I have also followed the instructions for installing the bluetooth firmware for the Broadcom chip on the XPS 13 2015 edition Wiki page.
I also made sure to enable ISCAN and PSCAN on my Bluetooth controller using the following command:
# hciconfig hci0 piscanThe controller is able to detect the mouse, but is unable to pair or connect it. Here my most recent attempt with bluetoothctl
(and I have verified that Device 00:1F:20:F7:41:8E is, in fact, the mouse):
# bluetoothctl

# Any ideas? I tried asking this in the Newbie Corner (post is here) and got no response.

Solved it! Apparently I failed to add the firmware to the kernel properly the first time around.
If you're having this same problem, try running (as root):
sudo journalctl | grep -i bluetoothIf you find lines saying:
(Mon dd time systemname): bluetooth hci0: Direct firmware load for brcm/BCM20702A1-0a5c-216f.hcd failed with error -2
(Mon dd time systemname): Bluetooth: hci0: BCM: Patch brcm/BCM20702A1-0a5c-216f.hcd not foundtry installing (or reinstalling) your Bluetooth controller firmware.
Instructions can be found here.
Here's what a successful attempt with bluetoothctl should look like:
