Sendspin Bluetooth Bridge infographic — features, architecture and deployment options

What is it?

Sendspin Bluetooth Bridge turns Bluetooth speakers and headphones into native Music Assistant players by bridging them to the MA Sendspin protocol.

Each configured Bluetooth device shows up as its own player in Music Assistant. You can keep playback local, group rooms together, manage Bluetooth from the web UI, and run the bridge on Home Assistant, Docker, Raspberry Pi, Proxmox VE, or OpenWrt.

Why the current release line matters

The bridge uses a multi-process runtime: the main app handles Bluetooth, API, and UI, while each speaker runs in its own Sendspin daemon subprocess with dedicated audio routing. Top-level WEB_PORT and BASE_LISTEN_PORT overrides make it easier to run multiple bridge instances or parallel HA addon tracks on one host. Advanced setups can pin a player to its own listen_port and override the advertised host with listen_host when needed. Stable, RC, and beta addons use separate ingress and player-port defaults so they are easier to distinguish and safer to test side by side. D-Bus disconnect detection, fallback polling, runtime diagnostics, and SSE status updates keep headless deployments manageable. Use the dashboard for pairing, diagnostics, logs, update checks, config backup/restore, and Music Assistant integration — or automate it through the REST API.

Multi-bridge deployment

Run multiple bridge instances against the same Music Assistant server to cover every room — each bridge handles the speakers within its Bluetooth range.
