💡 Curious about customizing #WirePlumber for embedded systems? I wrote a blog post breaking down the config structure, with tips from a real-world project.

- Use profiles + fragments for easy customization
- Strip down features for leaner setups
- Avoid pitfalls with desktop dependencies

💡 Did you know #PipeWire implements #Bluetooth #LEAudio on top of #BlueZ and #Linux? 🎧 🎵

While there are still rough edges, PipeWire today supports BAP, VCP, device sets, and even #Auracast broadcasting!

❓ Have you tried LE Audio yet?

📢 #PipeWire 1.4 introduces #Bluetooth telephony support, a new D-Bus API enabling apps to manage phone calls using the Bluetooth Hands-Free Profile (HFP) protocol. Check out my short tutorial on using this API from the command line and have fun calling! 📞

Introducing Bluetooth telephony support in PipeWire
PipeWire 1.4 is almost out of the door! One of the highlights of the new release — which I personally worked on and presented also recently on my FOSDEM talk — is Bluetooth telephony support.
