[SOLVED] Problems with bluetooth on Acer Aspire A715-75G

[pythagorasmk]

I have successfully installed Debian on my Acer laptop. Everything is working fine, except Bluetooth. I think that Intel Wi-Fi 6 AX200 is responsible for Wi-Fi and Bluetooth.
I cannot connect to my phone ( Honor 20 lite ), it cannot be found by my laptop. The output of the "sudo journalctl -b -r -p err" is:

Code: Select all

On this forum I have found that the message about the firmware is harmless. About other messages I cannot find relevant information about Debian.
Can somebody help me. If you need some other information about my configuration please feel free to ask.

In addition from previous information I have found this link https://bugs.debian.org/cgi-bin/bugrepo ... =803265#45
The sap server is not a problem in this case. Maybe the problem is pipewire.

Can you connect to any other type of BT device, such as earphones?

Are you using a GUI to see if it can detect available devices to pair, or something in the terminal?

I don't have any other Bluetooth device other then my Honor 20 lite, so I cannot say anything about whether I can use other Bluetooth devices.
I am using KDE. So I am using GUI to see if other devices are present in my neighborhood.

New information.
After restarting the laptop, I can see my phone, but when I click to connect to my phone, my laptop says "the connection to device failed".
It is interesting that I can send and receive files using the Bluetooth applet in KDE. I am satisfied with this, but also curious why the error message "the connection to device failed". Where is the log file for Bluetooth daemon?

After reading this post viewtopic.php?t=151557 and installing the package pulseaudio-module-bluetooth everything is working fine.
