Due to this I'm unable to get my bluetooth paired to my wireless devices.
I tried:
sudo apt search realtek bluetoothsudo apt search bluetooth sudo systemctl restart bluetoothsudo /etc/init.d/bluetooth startsudo systemctl restart bluetoothsudo apt search firmware-realtek-rtl8723cs-btsudo apt search firmware-realtek-rtl8723de-btsudo apt search firmware-realtek-rtl8723DE-btsudo hcitool -a.sudo apt install bluez bluez-firmwaresudo apt updatesudo apt upgradesudo systemctl restart bluetoothsudo dmesg | grep Bluetooth
Now I need to connect my bluetooth with wireless devices. What should I do? I'm also unable to install bluetooth driver for my 22.04.4 LTS ubuntu and its Realtek.
