I have a Dell XPS 15 9550. When I try to scan/connect/pair with things through bluetooth (with both bluetoothctl and gnome's builtin thing), it doesn't detect anything at all. although it says it's broadcasting.
I have everything I believe I need installed. Here's pacman -Qs bluetooth:

I have seen some people testify that disabling runtime-pm in their laptop-tools or whatever fixed the issue, which I tried and did not work.
I would appreciate any help.
Thank you.

I made it work!
Looking at the dmesg output, it's clear that it's expecting a "brcm/BCM-0a5c-6410.hcd" in /lib/firmware, but the AUR package is providing "brcm/BCM20703A1-0a5c-6410.hcd".
So I ran this command:
sudo cp /lib/firmware/brcm/BCM20703A1-0a5c-6410.hcd /lib/firmware/brcm/BCM-0a5c-6410.hcdAnd now it works.
So for people with this problem in the future:
Install bluetooth stuff as described by wiki pages (bluez, etc)
Install the relevant firmware for your card from the AUR
Figure out where the kernel is looking for the firmware from dmesg, move your installed firmware there
