Enable Bluetooth?

[seth...@gmail.com]

I just got a new AI board and wanted to play around with the bluetooth, but when I launch bluetoothctl, the list command says no controllers found.

Is there any information out there on setting up bluetooth on this board? I have google'd everything I could think of with no avail. I have run systemctl status bluetooth and there are no issues, am I missing something?

[Bryan Schneiders]

I haven't yet accessed the Wifi or Bluetooth capabilities on the board but am currently investigating the same.

The scripts distributed with the debian images are built for the WiLink 1835 module found in the BeagleBone Black Wireless board (http://www.ti.com/product/WL1835MOD).  See the bb-wl18xx-firmware package and associated files.

The BBAI board uses an AzureWave AW-CM256SM module instead.

https://github.com/beagleboard/beaglebone-ai/wiki/System-Reference-Manual#69-wireless-communication-80211-ac--bluetooth-azurewave-aw-cm256sm

The AzureWave site doesn't mention this particular module and has no software support information.  A leaked copy of their product documentation has hardware details:

https://storage.googleapis.com/wzukusers/user-26561200/documents/5b7d0fe3c3f29Ct6k0QI/AW-CM256SM_DS_Rev%2015_CYW.pdf

The AW documentation says this module is based on the CYW43455 chipset.  There may be helpful resources here: https://community.cypress.com/community/linux

[Bryan Schneiders]

Additionally, it appears there's a bb-bbai-firmware package that I've successfully enabled the wlan interface with but no bluetooth yet.  Even though the package claims to support bluetooth.

One more followup.  No solution yet, but I can confirm the presence of the bluetooth hardware.

There are some BBAI related Bluetooth scripts from https://github.com/RobertCNelson/boot-scripts/tree/master/boot under /opt/scripts/boot on the debian images.

And there's an hci0 interface listed in hciconfig but results in an error if you try to enable it.  It's also missing a MAC address:

$ ls -l /sys/class/bluetooth/hci0
lrwxrwxrwx 1 root root 0 Jan  7 20:03 /sys/class/bluetooth/hci0 -> ../../devices/platform/44000000.ocp/480d1000.mmc/mmc_host/mmc2/mmc2:0001/mmc2:0001:3/bluetooth/hci0

$ hciconfig

    TX bytes:0 acl:0 sco:0 commands:0 errors:0

$ sudo hciconfig hci0 up
Can't init device hci0: Input/output error (5)

I've seen example hciattach commands for raspberry pi boards with similar hardware, but I haven't found one that helps on the BBAI.  I'm hoping someone else can chime in.  I plan to test with other stock debian images from the beagleboard site, as I've been using customized images.  To determine if this is a kernel version issue or something I broke.

Just for reference, the official site for the Linux driver appears to be: https://wireless.wiki.kernel.org/en/users/Drivers/brcm80211  (this is for the mrcmfmac driver)

[Robert Forsyth]

My Linux laptop has Broadcom hardware for WiFi and Bluetooth, it often needs firmware downloaded which I have to do over wired Ethernet.

My dmesg shows no "brcm" lines

The wlan1 is working and I can enable Bluetooth from the GUI

hcitool dev shows no devices

My laptop has directory /lib/firmware/brcm/ with lots of binary files and some Broadcom files in /lib/firmware/BCM434*.hcd

dmesg shows

[] Bluetooth: hci0: BCM: chip id 70

[] Bluetooth: hci0: BCM43142A

...

[] Bluetooth: hci0: BCM43142A0 Generic USB Class 2 NonUHE @ 20 MHz

I hope this gives you a clue to solve your problem. My BBAI WiFi seems to just work, not tried Bluetooth.

[jonnymo]

Yeah, I am seeing the same issue.  i tried installing a newer version of bluez but that did not make a diff.

There is a script that seems like it is intended to enable Bluetooth on the BBs but there is nothing listed for the BBAI.

The script is called bb-wl18xx-bluetooth.

Inside it does a check for the type of board and running manually this shows:

$ cat /proc/device-tree/model | sed "s/ /_/g" | tr -d '\000'
BeagleBoard.org_BeagleBone_AI

There is no option for BBAI in the script so it just will disable the BT.

Cheers,

Jon

Well, the "bb-wl18xx-bluetooth" script is on it's way out, it served a
purpose to replace an ancient tool from ti called "uim". This "uim"
tool had one purpose, load the bluetooth firmware on the wl18xx,
configure the serial port and enable bluetooth. Well things change in
10 years, the kernel is now capable of loading the wl18xx firmware and
initializing the bluetooth..

Should the bb-bbai-firmware package work to enable Bluetooth on the BBAI (not the BBB)?

See my previous posts in this thread for details but I can't get it to function. For now I'm using a USB bluetooth dongle as an alternative.

bb-bbai-firmware just installs the firmware for the bbai, i thought it
worked thru bluetoothctl, it's been a few months since i looked at it.

[Jon Morss]

Sorry to dig this up again, but has this been fixed?  I am seeing the same issue with the latest image , "am57xx-debian-10.3-iot-tidl-armhf-2020-04-06-6gb.img.xz" where the bluetooth device does not appear to be working.

The WiFi is working but not the bluetooth device.

I moved to an external USB bluetooth device as a workaround. I would like to see a solution but couldn't afford the time to investigate further.

  Yeah, an external BT device might be the solution but if the BT/BLE feature is not support on the BBAI, then it should be stated as such and listed as WiFi only.

I've tried a few more things but still I can't get it to work or even show an address.

systemctl start bluetooth.service

I am not sure why 'hciuart.service' is missing:

$debian@beaglebone:~$ sudo systemctl status hciuart.service

Unit hciuart.service could not be found

$ sudo ls /lib/systemd/system/hciuart.service

From what I can gather, this is the BT device on the BBAI but I am not sure where to get a driver for it.

I'm not sure what else to try.

[Michele Xiloyannis]

Sorry to dig this up but I am having the same problem as jonn and Bryan with a BBAI. 

Has anyone found a solution, in the meantime? 

Thanks!!
