Hi winterheart, thanks for looking after these packages.

I'm having some trouble getting my bluetooth to work. I originally had this error: direct firmware load for brcm/BCM20703A1-0a5c-6410.hcd failed with error -2

After I got that file from your repository and put it in /lib/firmware/brcm I got the following error:

dmesg | grep -i bluetooth [ 3.898001] Bluetooth: Core ver 2.22 [ 3.898063] Bluetooth: HCI device and connection manager initialized [ 3.898071] Bluetooth: HCI socket layer initialized [ 3.898096] Bluetooth: L2CAP socket layer initialized [ 3.898099] Bluetooth: SCO socket layer initialized [ 4.052022] Bluetooth: hci0: BCM: chip id 102 [ 4.053030] Bluetooth: hci0: BCM: features 0x2f [ 4.069041] Bluetooth: hci0: BCM20703A1 [ 4.072049] Bluetooth: hci0: BCM20703A1 (001.001.005) build 0000 [ 5.673785] Bluetooth: BNEP (Ethernet Emulation) ver 1.3 [ 5.673790] Bluetooth: BNEP filters: protocol multicast [ 5.673799] Bluetooth: BNEP socket layer initialized [ 6.165479] Bluetooth: hci0: command 0x0a0a tx timeout [ 14.165755] Bluetooth: hci0: BCM: Patch command 0a0a failed (-110) [ 16.405760] Bluetooth: hci0: command 0x1001 tx timeout [ 24.405479] Bluetooth: hci0: BCM: Reading local version info failed (-110)

I've read through the other issues and it seems build 0000 is a silent error.

I don't think I have a wifi+Bluetooth device, and I'm not sure what else to try here. Do you have any info about this issue?

Hello.

I think you need to WiFi module get working with brcmfmac driver as described in README. I guess this is another combined WiFi+Bluetooth device.
