Due to this I'm unable to get my bluetooth paired to my wireless devices.
I tried:
sudo apt search realtek bluetooth
sudo apt search bluetooth
sudo systemctl restart bluetooth
sudo /etc/init.d/bluetooth start
sudo systemctl restart bluetooth
sudo apt search firmware-realtek-rtl8723cs-bt
sudo apt search firmware-realtek-rtl8723de-bt
sudo apt search firmware-realtek-rtl8723DE-bt
sudo hcitool -a.
sudo apt install bluez bluez-firmware
sudo apt update
sudo apt upgrade
sudo systemctl restart bluetooth
sudo 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.
