Recalbox 4.1 x64 stable on PC : is there a way to see if the onboard bluetooth is supported ?



  • Hi,

    I know that the new Recalbox 4.1 adds support for bluetooth internal board of the Rpi3, on top of many bluetooth dongles, but on my side i'm using a PC Intel NUC with onboard wifi and blutooth. The wifi is supported fine by recalbox, out of the box, but I have no idea about the integrated bluetooth chip, when I try to pair a controller it loads and then says "no controller found" but that's it.

    How do I know if the integrated bluetooth is supported and is there a list of supported ones ? Else I guess I got to buy a bluetooth dongle as we did before...

    NUC bluetooth chip is : Intel® Wireless-AC 8265 + BT 4.2 (last gen bluetooth)

    Thanks for your answers :)

    @maldorhan yup, SSH to the box or open a local terminal and type hciconfig



  • @substring said in Recalbox 4.1 x64 stable on PC : is there a way to see if the onboard bluetooth is supported ?:

    hciconfig

    Wow fastest answer ever ! :)

    I got this :

    /boot$ hciconfig
    hci0: Type: BR/EDR Bus: USB
    BD Address: 00:00:00:00:00:00 ACL MTU: 0:0 SCO MTU: 0:0
    DOWN
    RX bytes:86 acl:0 sco:0 events:4 errors:0
    TX bytes:12 acl:0 sco:0 commands:4 errors:0

    Edit : so I guess it's not supported ?



  • (Since there's no address right ?)

    @maldorhan could be a simple firmware problem. Do you know the BT chipset ? if not can you find it in dmesg ? or, with your pi plugged, go to http://recalbox/help and generate a support archive :)



  • Here's what I found in dmesg : (if I read the right part ?)

    @maldorhan Bull's eye ! looks like we're missing that driver for now



  • @substring Well, I'll just wait for it to be integrated (maybe?) in future releases and go buy a random generic bluetooth dongle for now I guess :D Thanks a lot for your help anyway !

    the file is available at https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/intel

    No idea yet where to drop it ... /lib/firmware/intel ? or /etc/firmware/intel ? No recalbox at hand for now.

    But i think we can make it available by default in a later release



  • @substring Oh wow thanks ! I answered before I saw your second answer, i'm gonna check if I can add it manually (I have no clue about that yet), and else wait for an update, thanks A LOT for considering it and again for your help !

    @maldorhan Once I get back home i'll have a quick look where the file is suppoed to be. I don't know if you're familiar with linux, but it may not be a funny moment for you to drop the file where it is expected. I'll give you the step-by-step if necessary



  • I have honestly no idea where to put it yet even if I know a bit of Linux but I'll make sure to look hard for it and if needed follow your (very much appreciated) advices when you get home



  • Seems to be /lib/firmware/intel doesn't work for now though



  • @Substring

    I get that after adding the files

    Bluetooth: hci0: Found device firmware: intel/ibt-12-16.sfi
    [ 1.858988] Bluetooth: hci0: Failed to send firmware signature (-38)

    Edit : this the the new message I get in dmesg, no idea how to bypass? the signature check or add one

    @maldorhan I'm still looking for, but anyway, keep checking with hciconfig because the firmware upload happens wuite early in the boot process, might need bluez to be started too



  • @Substring hciconfig still the same for now, dmesg fails because of this "fail to send firmware signature" error now so it finds the firmware but doesnt load it up for some reason, I have no idea what's this signature sending error is about, still googling it with no results yet, I'll try to reboot and wait a bit more

    @maldorhan try running modprobe -r btusb ; modprobe btusb and report back. If the first command fails, try rmmod btusb ; modprobe btusb



  • @substring rebooting gave me another error, that is really weird : (without to change anything since last signature error)

    modprobe -r btusb

    I can't seem to be able to run the modprobe command (command not found) (that's where my small Linux knowledge stops I guess)
