RC52810A的应用目标是2.4GHz蓝牙低能耗系统、人机交互设备(键盘、鼠标和远程控制)、手机配件、运动和医疗设备、Beacon标签、工业数据监测控制设备。用户可借此模块，以***的开发周期整合现有方案或产品，以最快的速度***，同时为企业的发展注入崭新的技术力量。
The application objective of RC52810A is 2.4 GHz Bluetooth Low Energy Expensive System, human interactive devices (keyboards, mouse and remote control), mobile phone accessories, sports and medical devices, Beacon labels, industrial data monitoring control devices. Users can use this module to integrate existing programmes or products with *** development cycles and to inject new technological forces into enterprise development. ***
RC52810A工作在桥接模式（透传传输模式）。桥接模式下，用户MCU可以通过模块的通用串口和移动设备进行双向通讯，用户也可以通过特定的串口AT指令，对某些通讯参数进行管理控制。用户数据的具体含义由上层应用程序自行定义。移动设备可以通过APP对模块进行写操作，写入的数据将通过串口发送给用户的MCU。模块收到来自用户MCU串口的数据包后，将自动转发给移动设备。此模式下的开发，用户必须负责主MCU的代码设计，以及智能移动设备端APP代码设计。
RC52810A works on bridge-link mode. Under the bridge-link mode, users can communicate in both directions through the generic serial port of the module and mobile devices, and users can manage certain communication parameters through specific serial AT commands. The specific meaning of the user data is defined by the upper-level application itself. Mobile devices can write on the module and the data will be sent to the user's MCU via a serial port. The module is automatically forwarded to the mobile device when it receives a data package from the user's serial port.
为了***程序的稳定性，模块上电500ms之后才开始正常工作。
does not start working until 500ms have been charged for the stability of the program.
