该实验是在“点到点无线通信实验”的基础上进行开发，节点A 作为发射模块，节点B 作为射频休眠实验的对象，PC 通过串口下达休眠和唤醒的指令给节点B，来实现对射频部 件的唤醒和休眠功能。串口的设置为波特率115200b/s，8 位数据位，1 位停止位，无校验位。-The experiment in the " point to point wireless communications experiment" based on the development and launch of the module as a node A, node B as a test object dormant radio frequency, PC through the serial port sleep and wake-up instructions issued to the Node B, to achieve the right wake-up radio frequency components and the hibernation feature. Serial port baud rate is set to 115200b/s, 8 bits of data bits, 1 stop bit, no parity bit.
