Help for Bluetooth support

lbls55 · April 13, 2020 at 4:12 PM

Hi friends,

I have a librelec 9.2.2 installed on a kind of Intel NUC (NVISEN Y-MU01, I7 processor). The combo M2 ngff wificard/bluetooth is a ATHEROS QCA9377. Unfortunately, only wifi is working, not the Bluetooth… in Windows 10, ID is USB\VID_0CF3&PID_E009&REV_0001, it's a QUALCOMM QCA9377 Bluetooth 4.1.

I also have a CSR8510 A10 USB dongle which isn't reconized too.

...is there any solution to activate at least one of it?

Thanks for your help...

LAURENT.

Please attach your dongle and provide a link to a log file.

QCA9377 is not currently supported in the kernel bluetooth tree. I've been looking at what config is missing/neeed to add support for Amlogic SDIO devices, but this is not a huge priority for me at the moment.

This is as far as I've got (not a huge effort): WIP: Bluetooth: hci_qca: Add compatible for QCA9377 · chewitt/linux@ffd3f65 · GitHub

ok, Chewitt, thanks for your answer...

actually.. linux/btusb.c at master · torvalds/linux · GitHub says it should be supported on the kernel side.

can you run "dmesg | paste" .. let's see if there's messages about missing firmware; share the URL

Code

[    3.392029] bluetooth hci0: Direct firmware load for qca/rampatch_usb_00000302.bin failed with error -2
[    3.392032] Bluetooth: hci0: failed to request rampatch file: qca/rampatch_usb_00000302.bin (-2)

^ hardware is detected but firmware is missing. I'll see if I can find it..

Ok, thanks Chewit!!!

Code

mkdir -p /storage/.config/firmware/qca
cd /storage/.config/firmware/qca
wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/qca/nvm_usb_00000302.bin
wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/qca/rampatch_usb_00000302.bin
reboot

^ run those commands and you should have the right firmware. If you confirm it works, it's trivial for us to add the firmware into a future LE release.

let us know..

Worked like a charm...everything is ok now!!! My Bluetooth headphones are appaired and fully working... thanks Chewitt for this incredible support!!!

Great. Can you confirm which BT device worked - onboard or USB?

lbls55 · April 16, 2020 at 6:34 AM

The device is a combo wifi/BT atheros QCA 9377 (The wifi part was supported, not the BT part but now you solved the problem 😃). The card is a ngff size working in an M2 slot on the motherboard. I'm using the x86/x64 Librelec version installed dual boot on the hard drive in a chinese Intel NUC like (NVISEN Y-MU01) small PC.

kernel-firmware: pick BT firmware for USB/QCA9377 cards by chewitt · Pull Request #4327 · LibreELEC/LibreELEC.tv · GitHub

^ once this is merged to our master development branch it will be picked into a collection of backports for LE 9.2.3, so once you bump to that you won't need the extra files in /storage/.config/firmware. Enjoy

Sorry in advance if I missed something, but I do run into the same problem with the exact same bluetooth hardware 0cf3:e009, running a x86_64 version of LibreELEC 9.2.6.

Manually downloading firmware did work out for me, but since this fix was merged a long time ago, I am wondering why it is not available out of the box in 9.2.6.

Again terribly sorry if I asked a dumb question. Not very familiar with how the development process works.
