Using a Raspberry Pi as a Bluetooth speaker with PipeWire
Do you have an old pair of PC speakers, or an old Hi-Fi, that you would like to convert into a pair of Bluetooth® speakers to play music from your phone? A Raspberry Pi can be easily used as an audio bridge between a Bluetooth® device and an analog speaker system, to make this possible. In this quick guide, I will show you how to set up the software on a Pi, using PipeWire, to achieve this.
In my demonstration setup, I am using a Raspberry Pi 3, which embeds a Bluetooth® chipset, and I am connecting an analog speaker to the 3.5mm jack. For the software, I am using RaspberryPi OS Lite with a recent PipeWire version installed from the Debian testing (Bookworm) repositories, as the version included in RaspberryPi OS (which is based on Debian Bullseye) is too old to support this use case.
