About

This gist will show how to setup Raspbian Stretch as a headless Bluetooth A2DP audio sink. This will allow your phone, laptop or other Bluetooth device to play audio wirelessly through a Rasperry Pi.

Motivation

A quick search will turn up a plethora of tutorials on setting up A2DP on the Raspberry Pi. However, I felt this gist was necessary because this solution is:

• Automatic & Headless - Once setup, the system is entirely automatic. No user iteration is required to pair, connect or start playback. Therefore the Raspberry Pi can be run headless.
• Simple - This solution has few dependencies, readily available packages and minimal configuration.
• Up to date - As of December 2017. Written for Raspbian Stretch & Bluez 5.43

Suppose I want to use an argument twice, as for example in the expression:
(\x -> (pred1 x) and (pred2 x))

Is there a shorter way of doing this?


liftA2 (&&) pred1 pred2

You can be cute and use the applicative instance on functions: 
(&&) <$> pred1 <*> pred2

Setup NixOS (Virtualized + Haskell + Gnome3 + XMonad)

Before you get started

This is pretty out of date now... you may want to look elsewhere

Newer guides than mine (mine is a bit dated and has a lot of rough edges):

• NixOS on MacBook Pro

Have you looked at these?
