Colibri IMX6 usb bluetooh: connmanctl error

Hi everybody,

I try to use an USB Bluetooth dongle:

root@colibri-imx6:~# lsusb
Bus 002 Device 007: ID 0a5c:2148 Broadcom Corp. BCM92046DG-CL1ROM Bluetooth 2.1 Adapter

I follow this page as instruction, and I get this message:

root@colibri-imx6:~# connmanctl enable bluetooth
Error bluetooth: Method "SetProperty" with signature "sv" on interface "net.connman.Technology" doesn't exist

I think my dongle is not well reconised, I’m right? (And I should get an other one in the list provided by TORADEX…)

hi @base

Welcome to the Toradex Community!!!

Could you provide the complete bootlog and the output of lsmod in a textfile? Which Software Version are you using ( cat /etc/issue ) for the module?

Thank you for the fast answer!

The : link Bootlog

The lsmode:

root@colibri-imx6:~# lsmod

Module Size Used by

usb_f_rndis 11788 2

u_ether 8965 1 usb_f_rndis

libcomposite 35410 10 usb_f_rndis

configfs 20477 3 usb_f_rndis,libcomposite

galcore 209125 10

And finally the cat:

Angstrom v2016.12 - Kernel

Colibri-iMX6_LXDE-Image 2.7b4 20171004


When you did the bootlog, was the dongle connected? Could you resend the bootlog after disconnecting any other USB device and then just connecting the USB Bluetooth dongle? Thanks.

Your dongle reported as a Mouse/Keyboard HID. Are you using correct dongle?

Thank you jaski: yes, the dongle was connected.

In attachement, the bootlog without the dongle, and connected manually at the end!

Alex made a good point. Could you send the datasheet of the dongle or are you suing a hub to connect all the USB devices at once? If so please connect only one device at one time? Thanks.

Many thank for your help, sorry for the delay. My dongle was an old one, no datasheet.
I bought 2 new, and advanced a bit in the development: I’m going to use Boot 2 QT.

So, here are all of my info:

And it’s not going any further.
I have nothing in the “rfkill list” (I try to follow this post, with the same dongle), but not better.
I try with “systemctl start bluetooth”, and something appear in the “systemctl status bluetooth.service”:

Have you any idea where the problem is?

Hi @base

Thanks for your Input. Could you try your dongle on the Bsp 2.8b6 LXDE Image and check if the dongle is working there or not?

Please provide also the output of lsmod and lsusb with the LXDE image?

Thanks and Best regards,

Hi @jaski.tx ,

Thank you for your answer, it has progressed well!

Here is the result, with the hot connection of the module:

Nice! So, the problem come from my QT Image? How can I proceed?

hi @base

These are good news. I am not sure which Kernel you are using for the Boot2Qt image. Could you update to the thud branch and check if bluetooth is working fine there.

Thank you!

I think there is no “qbsp” already packed?

I’m going to follow this:

I’m right?

I’m trying to build it…
I get the thud branch in the “meta-boot2qt” folder, and then:

~/Yocto/meta-boot2qt$ ./b2qt-init-build-env init --device colibri-imx6
~/Yocto/meta-boot2qt$ export MACHINE=colibri-imx6
~/Yocto/meta-boot2qt$ source ./ 
~/Yocto/meta-boot2qt$ bitbake b2qt-embedded-qt5-image

But it take so long! Right? Do I something wrong? (Sorry, I use Yocto for the first time…)

This is normal. The first build takes always some time to finish, but it depends also on the hardware of your build host.
