# redmi-buds-linux: rebuilding Redmi earbud controls over JieLi RCSP

> redmi-buds-linux reimplements Redmi and Xiaomi earbud controls on Linux using a documented variant of JieLi RCSP over Bluetooth Classic RFCOMM. The author derived the challenge-response transform from the companion app's native library and compared protocol behavior with a phone-to-buds HCI capture. Its Rust CLI and GTK app expose battery status, EQ, gestures and earbud finding; noise control is available on models with ANC.
