摘　　要：针对无线产品设计中的产品可靠性、功耗、有效距离和成本问题,设计了一款基于SI4432和STM32F103的高性能无线收发应用平台。设计中实现了ACK双向通信、精简CSMA/CA发送机制,增强了系统的可靠性,减少了由于数据冲突造成的数据丢失现象,可满足不同的应用需求。实验表明,该平台简化了无线产品的设计,可应用于安防、无线抄表、无线传感器网络等系统。Against the reliability, power consumption, valid transmit range and costs which are greatly concerned in the design of wireless products, in this paper a high-performance wireless transceiver application platform ＂based on STM32F103 and SI4432 is designed and SI4432. In order to meet the needs of different applications, designed the ACK bidirectional communication and the streamlined sending mechanisms based on CSMA/CA, which increased the stability of the system and reduced the data loss caused by data conflict. Experiments show that the platform can simplify the design of wireless products, so it can be widely used in home security,wireless meter reading, sensor networks and other systems.
