Bluetooth over Ethernet on a PoE ESP32 for remote gaming
An Olimex PoE ESP32 board relays Bluetooth over Ethernet so living-room game controllers reach a PC in a rack, built with Claude.
The full story
Fed up with Steam Link's latency, the maker used leftover hardware and a Claude subscription to build a remote Bluetooth adapter: an Olimex ESP32-POE board relays Bluetooth over Ethernet, with Zig firmware and a host daemon. Together with optical HDMI it gives a working gaming setup from a server rack to the living room.
The maker says controller inputs feel exactly the same as next to the machine. They plan to use it with Home Assistant too.
