I have a Sony svf1521bygb laptop
I installed Ubuntu 22.04 on it in uefi mode.
Bluetooth does not work by default.
With the following command, Bluetooth is activated,
Code:
cd /lib/firmware/brcm
sudo wget https://github.com/winterheart/broadcom-bt-firmware/raw/master/brcm/BCM43142A0-0489-e062.hcd
but it does not search for any of the devices.
Previously, I had no problem with the above command on Ubuntu 18.04 and 19.10.
Code:
