两个nRF模块通信示例
所需硬件
电路搭建 将Battery、Core、nRF堆叠在一起，通过MicroUSB数据线接入电脑，发射端与接收端硬件搭建相同。初次使用请参考：Getting Started。
代码 发射端程序: /*
[head,2byte,0xAA 0xBB] [type,1byte,TYPE_NUM] [data,16byte]
Example:
AA BB C8 DC 05 DC 05 D0 07 EF 03 DC 05 DC 05 DC 05 DC 05
*/
#include <Microduino_Protocol.h>
#define NRF_CHANNEL 70 //nRF通道
/* 预先设置好两个通讯地址，总长度为6位 */
uint8_t addresses[][6] = {"1Node","2Node"};
RF24 radio(D9, D10);
ProtocolnRF nrfProtocol(&radio, 16); //采用ProtocolnRF，数据长度为16个字节
uint16_t sendData[8] = {1500, 1500, 1500, 1500, 1000, 1000, 1000, 1000};
uint8_t sendCmd = 0x01;
uint32_t sendTime;
void setup() {
Serial.begin(9600);
//设置nRF通道， 本机地址，目标地址
if (nrfProtocol.begin(NRF_CHANNEL, addresses[1], addresses[0])) {
Serial.println("nrf24 module Initialization ");
}
else{
Serial.println("nrf24 module is not founded ");
}
}
void loop() {
if(millis() - sendTime > 1000)
{
sendTime = millis();
nrfProtocol.write(sendCmd, (uint8_t *)sendData, 16);
Serial.println("protocol send !");
}
delay(10);
}

Serial.println("protocol Received !");
Serial.print("recCmd: ");
Serial.print(recCmd);
Serial.print(" Data:");
for(uint8_t i=0; i<8; i++)
{
Serial.print(" ");
Serial.print(recData[i]);
}
Serial.println();
}
}
