ESP32 nrf24
Posted: Sun Jul 07, 2024 11:25 am
Hi. I just got into microcontrollers and started working on my first project, a transmitter and receiver. I have two nrf24 modules, an esp32 s3 and an esp32 c3. But, unfortunately, nothing is working. This is the code for the transmitter (esp32 s3):
}
And this is the code for the receiver (esp32 c3) :
It's probably a programming issue, but I cant seem to find it.
Code: Select all
#include <SPI.h>
#include <nRF24L01.h>
#include <RF24.h>
void begin(int8_t sck =12, int8_t miso =13, int8_t mosi =11, int8_t ss =10);
RF24 radio(10, 19); // CE, CSN
const byte address[6] = "00001";
void setup() {
radio.begin();
radio.openWritingPipe(address);
radio.setPALevel(RF24_PA_MIN);
radio.stopListening();
}
void loop() {
const char text[] = "Hello World";
radio.write(&text, sizeof(text));
delay(1000);And this is the code for the receiver (esp32 c3) :
Code: Select all
#include <SPI.h>
#include <nRF24L01.h>
#include <RF24.h>
void begin(int8_t sck =4, int8_t miso =5, int8_t mosi =6, int8_t ss =7);
RF24 radio(7, 3); // CE, CSN
const byte address[6] = "00001";
void setup() {
Serial.begin(9600);
radio.begin();
radio.openReadingPipe(0, address);
radio.setPALevel(RF24_PA_MIN);
radio.startListening();
}
void loop() {
if (radio.available()) {
char text[32] = "";
radio.read(&text, sizeof(text));
Serial.println(text);
}
}
