We are looking for a developer experienced with Linux, GStreamer, and BlueZ to work on a real-time audio pipeline project. The project uses two embedded Linux devices (Raspberry Pi 3s running Debian Jessie); a hub and a satellite. The hub must: - be discoverable over Bluetooth - generate a WiFi network - act as a Bluetooth A2DP sink, so that any device connected can send it audio. - send the audio received from Bluetooth to its WiFi network using RTP (using GStreamer) - send the audio received from Bluetooth to its audio output The satellite must: - connect to the hub's WiFi network - receive audio through RTP and send it to its audio output In addition, clocks must be synchronized so that the audio plays with no noticeable time delay from the two devices.
