摘要
为实现短距离内点对多点数据传输,根据汽车四轮定位仪一主四从和单包数据不大于16 Bytes的要求,基于蓝牙协议在CSR公司蓝牙软件开发环境BlueLab中实现了点对多点的无线数据传输,并设计了一对四即插即用蓝牙无线数据透明传输模块。在实验室环境中对蓝牙模块进行了测试。结果表明,该模块可完整接收发送端数据,达到了四轮定位仪实时正确收发数据的要求。
In order to achieve wireless point to multipoint data transmission in a short distance,according to the requirements of automotive wheel alignment that is one point to four points and the data packet is less than 16 Bytes,the achievement was realized based on the bluetooth protocol and BlueLab that is a bluetooth software development tool of CSR company,and a plug and play wireless bluetooth module was designed.The module was tested in the lab.The results show that the module can receive the complete data from the sender,meet the requirements of sending and receiving real-time data correctly in the wheel alignment system.
