1 Introduction

The TWS earbud case is an essential accessory for wireless earbuds. It not only provides a convenient storage solution but also charges the earbuds when not in use. Additionally, the case can communicate with the earbuds using a single-wire interface based on universal asynchronous receiver/transmitter (UART).
