LibreELEC with Intel AX210 PCI-e card. Wifi works but Bluetooth doesn't

geekfisher · June 23, 2022 at 4:52 PM

lspci | grep -e Intel

03:00.0 Network controller: Intel Corporation Device 2725 (rev 1a)

dmesg | grep -e Blue output:

[ 208.712549] Bluetooth: hci1: Reading Intel version information failed (-22)

[ 208.712554] Bluetooth: hci1: Intel Read version failed (-22)

[ 208.712607] Bluetooth: hci1: Intel reset sent to retry FW download

I tried copying this firmware .ucode: https://wireless.wiki.kernel.org/_media/en/user….601f3a66.0.tgz

to

/storage/.config/firmware and it seems to get to the overlays correctly but still doesn't load.

I've tried adding:

Kodi-Salon:~/.config/firmware/intel # ls -lah

-rw-r--r-- 1 root root 13 Jun 23 12:55 ibt-0040-0041.ddc

-rw-r--r-- 1 root root 730.1K Jun 23 12:55 ibt-0040-0041.sfi

-rw-r--r-- 1 root root 9 Jun 23 12:55 ibt-0041-0041.ddc

-rw-r--r-- 1 root root 671.3K Jun 23 12:55 ibt-0041-0041.sfi

To no luck

Please share the whole dmesg log (via pastebin). It's not clear which LE image you are using.

10.0.2 Generic with a 5.10 kernel which should normally supports the AX210 both wifi and BT.

Looks like the firmwares weren't there and adding them doesn't solve the issue. btintel.ko module is loaded but modinfo indicates it doesn't use the right Bluetooth firmwares

I'll get a dmesg pastebin and btintel modinfo after work

Test with a current nightly, as that will have newer kernel, drivers and firmwares.

I'll do.

According to this post your BT device is not supported from kernel 5.10.

**chewitt** · June 30, 2022 at 4:34 PM

..but should be supported in newer kernels, so the nightly will probably work.

geekfisher · July 3, 2022 at 6:58 PM

OK so I tried LE10 nightly from june 28th. It still has a 5.10 kernel but the build is a tad more recent and it still doesn't work. I'm writing an LE11 nightly USB stick ATM so we'll see. I used Generic-legacy as I have an nVidia GeForce 1030 in this one. We will see

geekfisher · July 3, 2022 at 10:25 PM

On LE11 nightly from July 3rd, Bluetooth is working fine but wifi cannot detect hidden SSIDs (Bug Report filled). I disconnected the motherboard USB header and ordered a Bluetooth 4.x usb dongle for the time being but at least I know I'll be able to update it to LE11 when the time comes.
