Don’t download this. It’s a curl | bash installer for a binary whose sources appear to just … be the popular FOSS bluez tool, which it downloads and builds, and whose binaries are checked into the repo. But it could just as easily be malware.<p>Assuming that this repo is well intentioned, <i>this should have been a blog post</i> on how to install bluez for your platform and use its proxy tool, with some shell one liners provided to make that easy. Not a curl | bash installer for something totally opaque, which turns out to be another project’s software basically renamed into this repo.<p>This is not the way. Also potentially a license or trademark/name issue.

Or just buy a $15 dongle instead of the crap interference-laden onboard BT and have problem-free USB passtrough as well.

Hi HN, I built this after hitting a wall with Bluetooth passthrough on Proxmox: Intel's onboard Bluetooth/WiFi combo chips (BE200, AX210, AX211, and others) are built so only the machine that boots them can drive them. Hand the chip to a VM via USB passthrough and it wipes its own firmware, no setting fixes it. It's how the hardware works. Also flaky on gaming distros like ChimeraOS/Bazzite even with add-on dongles :-/<p>Instead of fighting passthrough, this keeps the adapter on the Proxmox host, let's share it into the VM over the local network via BlueZ. 2 simple commands: run the installer on the host, run it again inside the VM pointing at the host's IP. The VM sees a normal Bluetooth adapter and pairs like usual. Both sides auto-reconnect on reboot.<p>Works for game controllers in a gaming VM, Home Assistant BLE sensors, headphones, anything that expects a normal adapter.<p>I would be happy to answer questions about the approach.
