set up bluetooth on rasberry 3

sudo apt-get update
sudo apt-get upgrade -y
sudo apt-get dist-upgrade -y


sudo apt-get install pi-bluetooth

You may then need to update the firmware used in the Bluetooth module, which is done by running the following:

sudo apt-get install bluez bluez-firmware

To fix Raspberry Pi 3 Bluetooth issues, you need to run the following code in your terminal:

sudo usermod -G bluetooth -a pi

And to check this has worked, type:

cat /etc/group | grep bluetooth

if ok ---> bluetooth:x:113:pi

Then reboot

sudo reboot
