The lucid-fabrics/proxmox-bluetooth project solves Bluetooth passthrough failures on Proxmox VMs, especially for Intel BE200, AX210, and AX211 chips that cannot be passed through by hardware design. Instead of handing the chip to the VM, this tool shares the host's Bluetooth adapter over the local network. Setup takes two commands: run the installer on the Proxmox host, then run it inside the VM with the host's IP.

The VM sees a normal Bluetooth adapter with latency under 1ms. It works on ChimeraOS, Bazzite, Home Assistant, and any Linux guest, supporting controllers, headphones, keyboards, and BLE sensors simultaneously. Pairings survive reboots and OS updates.

For stuck Intel chips, a full power-cycle (PSU off for 15 seconds) resolves the bootloader issue. The bridge binds to port 9700; firewall it to the VM's IP for security. Windows VMs and LXC containers don't need this — USB passthrough works natively there.
