说明：  1、 简单的发送和接收0x01-0x08这几个 数据，收到取反LED灯，比官方的例程更简单易懂 2、 板子上的RF的天线参数没有经过验证和阻抗测试，只是能收发数据用，做产品时自行到检测机构测试。 3、 发送和接收模式切换，只要更改初始化程序的最后2行。
(1. Simply send and receive the data of 0x01-0x08, and receive the reverse LED lamp, which is simpler and easier to understand than the official routine. 2. The antenna parameters of RF on board have not been validated and impedance tested, but can send and receive data. When making products, the antenna parameters of RF can be tested by the testing mechanism. 3, send and receive mode switching, just change the last 2 lines of the initialization program.)
