Bluetooth is a wireless technology standard managed by the Bluetooth Technology Alliance (SIG). Bluetooth is designed for short-range data transmission and exchange, using the unlicensed ISM band of 2.4 GHz. Bluetooth is rich in features, including point-to-point audio streaming and large-scale many-to-many mesh networks for lighting or home automation.
WCH provides Bluetooth MCU based on self-developed RF technology and baseband algorithm. Bluetooth MCU is equipped with mature network protocol stack, rich sample code and multi-platform APP tools. Some chip models can be used without secondary development; Provide characteristic Bluetooth/serial /USB three-way chips to empower more complex wireless applications.
