This was working fine a weeks ago, but now when I try to send a file to my computer from my phone via bluetooth, it results in "Connection failed." I noticed that if I look in the GNOME Bluetooth settings, the status will keep going from "Connected" to "Disconnected" and back again. This is also evidenced by bluetoothctl.

$ bluetoothctl
[NEW] Controller 00:02:5B:11:04:D8 BlueZ 5.18 [default]
[NEW] Device 24:C6:96:16:49:37 Drew
[bluetooth]# connect 24:C6:96:16:49:37

[CHG] Device 24:C6:96:16:49:37 Connected: yes

The weird thing is that transferring a file from the computer to the phone is working fine. Restarting the phone, and re-pairing has made no difference.

Posting this and the answer in case I run into the problem again. –  druciferre May 18 at 0:12

Running this command resolved the problem.

# hciconfig hci0 up

Even though, the device hci0 displayed an UP status when running hciconfig, this still fixed the problem for some reason.

The idea to try this came from https://bbs.archlinux.org/viewtopic.php?id=172261
