Bluetooth used to work; now doesn't. Nothing has changed. Help?

Hi folks. I've been using Arch for years but am still a N00b because shit always breaks for no reason and I can't get it fixed without having someone on the forum tell me some secret trick.

Often this is because I didn't read the wiki carefully enough but in this case, there is basically nothing on the wiki-- it's all pretty basic and seems like it should just work.

And in fact it DID just work the last tme I tried it-- about in April-- I installed bluez-5.44-1 and bluez-utils-5.44-1 and paired with my phone and transferred a picture and all was well.

Fast forward to now, a couple of pacman -Syu later, a couple of restarts later, and now bluetooth is just a giant pile of shit.

The module is loaded:

[root@ember bluetooth]# lsmod | grep btusb
btusb                  40960  0
btrtl                  16384  1 btusb
btbcm                  16384  1 btusb
btintel                16384  1 btusb
bluetooth             487424  41 btrtl,btintel,bnep,btbcm,rfcomm,btusb
usbcore               208896  7 uvcvideo,usbhid,ehci_hcd,xhci_pci,btusb,xhci_hcd,ehci_pci

Systemctl status bluetooth shows normal performance:

[root@ember bluetooth]# systemctl status bluetooth
● bluetooth.service - Bluetooth service
   Loaded: loaded (/usr/lib/systemd/system/bluetooth.service; enabled; vendor preset: disabled)
   Active: active (running) since Fri 2017-06-16 21:34:00 PDT; 7min ago
     Docs: man:bluetoothd(8)
 Main PID: 1935 (bluetoothd)
   Status: "Running"
   CGroup: /system.slice/bluetooth.service
           └─1935 /usr/lib/bluetooth/bluetoothd

journalctl doesn't show anything.

It's not rfkill:

[root@ember bluetooth]# rfkill list
0: tpacpi_bluetooth_sw: Bluetooth
	Soft blocked: no
	Hard blocked: no
1: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no
6: hci0: Bluetooth
	Soft blocked: no
	Hard blocked: no

It just never connects.

My phone can't see my computer, my computer can't see my phone. When I run bluetoothctl and tell it to scan, the scan never completes.

[root@ember bluetooth]# bluetoothctl
[NEW] Controller C8:FF:28:5B:31:BC ember [default]
[NEW] Device 5A:5A:5A:A6:31:1C S3020S
[bluetooth]# power on
Changing power on succeeded
[bluetooth]# scan on
Discovery started
[bluetooth]#scan on
Failed to start discovery: org.bluez.Error.InProgress
[bluetooth]#

Isn't it supposed to tell me that Discovering: YES, and then show me nearby devices? it never does.

When I use gnome-bluetooth or blueman it just doesn't give me any love: no errors, no failure notices, but no connection either. In gnome-bluetooth case, the spinning circle just spins.

I recently upgraded to bluez-5.45-1 and so I tried downgrading, but that was not effective either.

I don't know what to do- I've read the wiki page up and down. What should I try next?
Thanks in advance.

Thanks for the tip. Backtick notation didn't work.

Anyway, it occurs to me that one thing that did change was the phone... which is a Galaxy S6 and apparently the recent upgrade caused bluetooth issues with headset pairings.. so why not laptops? anyway, maybe that is the explanation.

Try runnig agent on before scan.

Arch Linux
