Need help on a bluetooth dongle connection issue

Recommended Posts

I setup a Dell T20 with DS3615xs of Jun's loader. I did check the hardware compatibility list. Then I bought a Kinivo BTD-400 Bluetooth dongle because it is in the list. 

When I connect it, it doesn't work. The blue light is up. I did check dmesg and /var/log/messages. I found the firmware is missing. It seems to me the DS3615XS doesn't support it at all. Never mind, I download the firmware and put it in /lib/firmware/brcm folder. Then I found there is maybe a bug for this BT support because when I direct plug the dongle in, the DSM expects BCM20702A0-0a5c-21e8.hcd. But when I reboot, it asks for "BCM920702 Bluetooth 4.0-0a5c-21e8.hcd". It is so upset. Do they really have QE?

 

Anyway, I put both name in that folder. Then check the log again, it seems like the firmware is loaded successfully. However, the kernel suddently killed it.

2018-12-30T03:07:30-08:00 DiskStation bluetoothd[8747]: Failed to open RFKILL control device

2018-12-30T03:07:31-08:00 DiskStation bluetoothd[8747]: Unknown command complete for opcode 19

 

There are no further information provided. I don't know what can I do now. Can anybody give some clue? I did check the bluetoothd service, it is disabled. I enabled it manually but it still the same. It doesn't work. There is nothing showing up from control panel -> wireless -> bluetooth. 

 

I checked hdiconfig -a, it looks good.

 

 

thanks
