[arduino code examples for A6v3]-10 nRF24L01 wireless receiver and transmitter - admin - 01-15-2025
nRF24L01 Transmitter:
Code:
#include <SPI.h>
#include <nRF24L01.h>
#include <RF24.h>
#define CE_PIN 40
#define CSN_PIN 38
const uint64_t abc = 0xE8E8F0F0E1LL;
RF24 radio(CE_PIN, CSN_PIN);
char data[] = "Hello World, KinCony";
void setup()
{
Serial.begin(9600);
radio.begin();
radio.openWritingPipe(abc);
}
void loop()
{
radio.write( data, sizeof(data) );
}nRF24L01 Receiver:
Code:
#include <SPI.h>
#include <nRF24L01.h>
#include <RF24.h>
#define CE_PIN 40

const uint64_t id = 0xE8E8F0F0E1LL;
RF24 radio(CE_PIN, CSN_PIN);
#define SIZE 32 // this is the maximum for this example. (minimum is 1)
char buffer[SIZE + 1]; // for the RX node
uint8_t counter = 0; // for counting the number of received payloads
