Hey,
I have a notebook with a Dell DW1890 that integrates a BCM20703A1 bluetooth controller. It needs a proprietary firmware blob available in the AUR to work at all [1]. After installing it, I am still unable to connect to most LE devices (Classic BT works fine). I'm trying to connect to a Logitech R500 wireless presenter in Bluetooth mode (works flawlessly under Windows).
I tried blueman and bluetoothctl directly, the error message (bluetoothctl -> connect xx:xx:xx:xx:xx:xx) is:
[CHG] Device xx:xx:xx:xx:xx:xx Connected: yes
Failed to connect: org.bluez.Error.Failed
[CHG] Device xx:xx:xx:xx:xx:xx Connected: no
The system log contains a few lines of
Bluetooth: hci0: last event is not cmd complete (0x0f)
Any ideas or similar problems?

It looks like there are some different firmware versions available e.g. here:

If you prefer the "official" source from MS update, it is here: https://www.catalog.update.microsoft.co … 0Bluetooth

Thanks for the quick reply!
I have already tried the firmware found on my Windows installation and I just tried all four firmware versions found in the file you linked. Unfortunately, all exhibit the same behavior (the firmware was loaded successfully, I checked the version output in journalctl after each shutdown/reboot):
