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。
Aiming at the problems of product reliability, power consumption, effective distance and cost in wireless product design, a high performance wireless transceiver application platform based on SI4432 and STM32F103 is designed. The design achieves two-way ACK communication and simplifies the CSMA / CA sending mechanism to enhance system reliability and reduce data loss caused by data collisions, so as to meet different application requirements. Experiments show that the platform simplifies the design of wireless products and can be applied to security, wireless meter reading, wireless sensor networks and other systems.
