Realtek Bluetooth driver on Debian 11

[dan748]

Dear All,

Hope to write in the correct section..

I'm having some issues with bluetooth radio (Realtek 2852): it seems working, but it continue to search devices without success;

Here the devices list:

Here the system info:

Linux Debian-HP 5.10.0-18-amd64 #1 SMP Debian 5.10.140-1 (2022-09-02) x86_64 GNU/Linux

the only explanation I have is the device is not supported by the kernel version...

Any suggest?

Kind Regards and Happy New Year
