# Audionic Trance Airbud 850: reconstructing BLE controls for Linux

> A Linux client reconstructs Audionic Trance Airbud 850 BLE controls from analysis of the Audionic Suite Android app and Jieli SDK references. It implements RCSP framing, mutual authentication and GTK controls for battery status, audio modes and EQ; the author reports using REA with JADX during the static investigation.
