LEGO Mindstorms EV3 Audio Streamed via Bluetooth Audio

Whilst displaying my Robots at a major Exhibition, I got to thinking that it would be great to pipe the EV3’s Audio to a Bluetooth Speaker, so my robot can be heard among the noise of a crowd.
Here are my notes so far on getting started with Connecting a LEGO Mindstorms EV3 Brick to a Bluetooth Audio Speaker:

  • Debian jessie is using BlueZ 5 and PluseAudio 5, which are fairly new. There were major breaking changes in these versions, so most stuff you find on the Internet will be for BlueZ 4/PulseAudio 4, so it does not work at all, so watch out.
  • BlueZ 5 dropped support for alsa [1], so the solution for now (until someone updates some bluez-alsa project for BlueZ 5) is to use PulseAudio.
  • PulseAudio 5 only supports the A2DP profile and not HSP/HFP [2] (although it his under development [3]).

Lets Start:

Direct connection of Bluetooth gamepads to the EV3 Brick

In this project we show that a small C program running on the EV3, brickhid, can handle Bluetooth communications with a PlayStation 3 controller and translate stick positions and button codes into motor commands.
