Hi, I just recently added arch linux to dual boot in my laptop, but I am having a little trouble that's preventing me from using my bluetooth keyboard.
I have already gone through the troubleshooting guide for Bluetooth in the wiki.
I have gone through countless forum posts about it and I am just going here out of desperation that even after two days I just cannot figure out what is going on.
Just as the subject suggests, bluetooth does not appear in lsusb, rfkill, bluetoothctl list (or show).
Here are the things I have tried that might help clarify this issue (following through what other people did when they asked for the same problem)

Do you know the chip that the bluetooth thing uses and does it require drivers not in linux-firmware?
Be smart and use root responsibly.

I actually tried getting other drivers last night, but I'm not sure it worked.
My laptop is an Acer R3-471T, and I guess it uses Intel Dual Band Wireless-AC 3160 for both its bluetooth and wifi.
I have tried downloading the latest drivers from https://www.intel.com/content/www/us/en … eless.html and installing it as suggested from other forum posts

Sorry I have not responded in a bit. Is the driver loaded because it sees it but nothing else communicates with it and you sure nothing is disabling it? Another guess would be try the linux-lts to see if it works.

Maybe try using bluetoothctl in tty. I'm a newbie to Arch and had bluetooth problems too when the DE bluetooth client somehow messed with it. So tty worked for me.

Sadly didn't work. It seems that linux doesn't recognize any bluetooth hardware.

Sometimes if a chipset combines bluetooth and networking capabilities it can be an issue. Try adding 'options iwlwifi bt_coex_active=0' to '/etc/modprobe.d/iwlwifi.conf' and reboot. If it doesn't help, be sure to remove that line, reboot, and keep trying other things.
