Bluetoothctl Failed to pair: org.bluez.Error.ConnectionAttemptFailed

Help me out, I am trying to pair with a Bluetooth speaker "JBL FLIP", I already installed `pulseaudio-bluetooth` and tried updating the firmware through `b43-firmware` from the AUR.

I can pair just fine from my iphone and from my windows pc.

Here's me trying to pair:

[bluetooth]# devices
Device 0C:A6:94:88:6C:8F JBL Flip 2
[bluetooth]# pair 0C:A6:94:88:6C:8F
Attempting to pair with 0C:A6:94:88:6C:8F
Failed to pair: org.bluez.Error.ConnectionAttemptFailed
[bluetooth]#

Re: Bluetoothctl Failed to pair: org.bluez.Error.ConnectionAttemptFailed

The dmesg log indicates the firmware (.hcd file) for your Broadcomm adapter is missing (lsusb for the exact model) :

[    5.016968] bluetooth hci0: Direct firmware load for brcm/BCM20702A1-0a5c-216f.hcd failed with error -2

You can look directly into the Archlinux wiki that provides hints about finding and installing the firmware.

(unrelated : grep -i <term> will search case insensitive)
