# moldqueen: Mould King toy control through reconstructed BLE advertisements

> moldqueen controls Mould King building-block toys by encoding commands as BLE advertisements derived from a reconstructed device protocol. Raspberry Pi, Android and ESP32-S3 radio cores expose a shared WebSocket API to a browser client; the Mould King 13112 excavator is the documented hardware reference.
