It gave me immediate access to transfer files to my tablets and phones so I could print using Wireless Direct to my wireless printers.
But as someone kindly commented here - it did not work with Audio. So I deleted the original post and changed a few things so I could connect by bluetooth to my Logitech S00113 Bluetooth Audio Adapter.
Here's what I did. I use Synaptic, so finding what is installed is easy.
sudo apt-get install synaptic
First, I made sure that bluetooth was installed, then checked that pi-bluetooth was also installed. pi-bluetooth loads the drivers for the new on-board bluetooth in the raspberry Pi 3B.
Then it was time to add a few tools:
sudo apt-get install bluez
sudo apt-get install pulseaudio
sudo apt-get install pulseaudio-module-bluetooth
I also have bluez-tools. It should have been installed by bluez. If it was not, it doesn;t hurt to install it.
then, just in case I want to use pulse for anything else
sudo apt-get install pavucontrol
pavucontrol is not really needed. But there are times I use the pulse volume control for other things.
I am listening to music playing from my Raspberry Pi 3 to my blueooth system as I write this.
