A2DP = audio HSP = headset profile AVRCP = remote control
Bluetooth 2.x
I have a module that does TTL serial <-> bluetooth, played with it a few times. Way back then I paid $65 for it, yipes yipes!
EDR = extended data rate
There are $4-6 modules that do basic Bluetooth - serial conversion.
HC-05 based : Master or slave: http://www.banggood.com/HC-05-Wireless-Bluetooth-Serial-Transceiver-Module-Slave-And-Master-p-908621.html
HC-06 based Slave only: http://www.banggood.com/HC-06-Wireless-Bluetooth-Transceiver-RF-Main-Module-Serial-For-Arduino-p-80364.html
Stereo audio + UART: The UART is for programming the module, not for SPP http://www.banggood.com/Mini-XS3868-Bluetooth-Stereo-Audio-Module-OVC3860-For-A2DP-AVRCP-p-932285.html See https://hackaday.io/project/2273-integrating-the-xs3868-bluetooth-module
Bluetooth Low Energy (BLE)
aka Bluetooth 4.0
These modules have gotten so cheap it's almost scary.
Fun article: http://www.instructables.com/id/BluTag/
They use a $59 LinkIt One, http://www.seeedstudio.com/depot/LinkIt-ONE-p-2017.html which is a complete ARM based card that has GPS, Bluetooth and BLE, WIFI, even GSM, basically it's a cellphone with no case.
They also use a TTL - BLE module that's about $4. http://www.banggood.com/HM-10-CC2541-CC41-Bluetooth-4_0-UART-Transceiver-Serial-Module-p-955689.html
Bluetooth on Bellman
Objective: run Squeezebox server and send its audio stream to bluetooth speakers or headset.
First make the Bluetooth work. Install packages.
apt install bluez-tools bluez blueman rfkill apt install pulseaudio pulseaudio-module-bluetooth pavucontrol
Make sure BT hardware is visible and available; looks good.

At this point I need to start pvaucontrol which is an X client. So I need a Mac or to know how to run X on Windows in the year 2019. I am trying Cygwin/X. Installing now.
Using X11 on Windows 10
Install Cygwin with X11 packages including xinit xorg-server xterm and xlaunch
Connnecting to the Bose speaker, later on
Run xlaunch and select multiple windows and tell it to launch xterm.
In the xterm window,
ssh -Y bwilson@bellman
Push the bluetooth pairing button on the bluetooth speaker to wake it up.
In the xterm window use bluetoothctl
Enter the connect command,
connect 2 (tab)
The speaker should say "Connected to bellman".
Rejoice!
Now you can run pavucontrol. You should be able to see the speaker.
Now you should be able to run vlc on Bellman and play anything in /home/music
Now for the Squeezebox thing. I need a client to run on Bellman that will be visible to the Logitech Media server running on port 9000.
I eneded up using squeezelite from the Debian repostory. I was able to run pavucontrol by installing Cygwin/X on Murre and then running xterm in a window and using ssh -Y bellman. Then run pavucontrol in that shell. It opens on the Windows 10 screen. Likewise if I run anything there for example vlc it will open on the Windows 10 machine.
I ended up running squeezelite as myself since I had access to bluetooth and sound devices. I can control the output via Logitech Mediaserver
I used the synchronize option to sync the red box and Bellman and have audio come out on the Bose speakers. Syncing them means the red box can be used to control the output of the speakers.
