Hi @kevin.tx,
I have done the same tests on a PC with Linux and no problems, however with imx8mm I still have errors:
Failed to connect: org.bluez.Error.Failed br-connection-profile-unavailable
Failed to connect: org.bluez.Error.Failed br-connection-create-socket
Any suggestions, have you been able to run any other tests or find a solution?
Best regards,
Julián
Hi @jbruno ,
Sorry for the lengthy delay.
Unfortunately, I haven’t been able to find a solution yet. I will come back to you as soon as possible.
I have to apologize for the inconvenience.
Best Regards
Kevin
Hi @jbruno ,
These devices emulate a keyboard and/or mouse. It seems to be something SW related to HID, but we are not sure.
On my side I can’t seem to connect to HID Bluetooth devices as well, with the same br-connection-create-socket error. I’m using a similar setup as yours (Verdin iMX8M Mini with the minimal BSP ref. image 6.3.0)
It could be due to missing drivers on the kernel i.e. a config option not enabled, though I’m just guessing.
There is a recently updated issue reported on the bluez GitHub page that is similar to what you’re seeing:
Maybe it’s related to your issue.
As for the br-connection-profile-unavailable errors with the heasets, you may need to build a custom image with the oFono HFP profile, as documented here:

Hi @lucas_a.tx,
Thank you very much for your comments. I have tried to update the version of bluez in Yocto and it won’t let me upgrade from version 5.65.
Regarding the other issue you mentioned, I have the oFono HFP profile active.
Hopefully we will find a solution soon or someone from the forum can help us 
Best regards,
Julián
