Any advice for nRF52832 to nRF24L01+ communication?

[moso]

Hi, I tried establish a communication between nRF52832 DK(PCA10040) to nRF24L01+ Module with Arduino UNO(via SPI). I used the EnhancedShockburst examples from nRF5 SDK 11.0.0 but couldn't receive any data from nRF52. I use TMRh20's RF24 libraries in Arduino. This is my config:

#include <SPI.h>
#include <RF24.h>
#include "nRF24L01.h"
#include "printf.h"
RF24 radio(7, 8);
#define SERIAL_DEBUG
uint8_t message[1];
const uint64_t pipes[2] = {0xE7E7E7E7E7LL,0xC2C2C2C2C2LL};
void setup()
{
Serial.begin(57600);
printf_begin();
radio.begin();
radio.setRetries(15, 15);
radio.setChannel(2);
radio.setPALevel(RF24_PA_MAX);
radio.setCRCLength(RF24_CRC_8);
radio.setDataRate(RF24_2MBPS);
radio.setPayloadSize(1);
radio.enableAckPayload();
radio.openWritingPipe(pipes[0]);
radio.openReadingPipe(0, pipes[0]); 

radio.startListening();
radio.printDetails();
}

void loop()
{
radio.startListening(); // Start listening for incoming messages

while ( ! radio.available() ) { // Wait for a message
 delayMicroseconds(10);
}

radio.read( &message, 1); // Get the message
Serial.print(" DATA:      ");
Serial.print(message[0]);
Serial.println("  END  ");
}

The nRF52 side, I didn't change anything expect choose legacy config parameters like:

#define NRF_ESB_LEGACY

There is no data received that can I see. Is there any idea about mistakes?

Sincerely,

thanks.

The communication is okay, now. Changing anything at nRF52 side and choosing default configuration(not legacy) worked for me. The nRF24 side my working code is below:

#include <SPI.h>
#include <nRF24L01.h>
#include <RF24.h>
#include "printf.h"

RF24 radio(7, 8);
int packetCounter = 0;
uint8_t incoming_data = 0;
uint8_t message[1];

int64_t pipe_adress[2] = {0xB3B4B5B601, 0xE7E7E7E7E7};

void setupRadio()
{
  radio.begin();
  radio.setRetries(15, 15);
  radio.setChannel(2);
  radio.setDataRate(RF24_2MBPS);
  radio.setPALevel(RF24_PA_MAX);
  radio.enableDynamicPayloads();
  radio.openReadingPipe(1, pipe_adress[0]);
  radio.openReadingPipe(0, pipe_adress[1]);
  radio.startListening();
  radio.printDetails();
}

void setup() {
  Serial.begin(115200);
  printf_begin();

  setupRadio();
}

void loop() {

  if (radio.available()) {

    radio.read(&incoming_data, sizeof(int));

    Serial.println("DATA:    ");

    Serial.println(incoming_data, BIN);
    Serial.println(incoming_data, OCT);
    Serial.println(incoming_data, DEC);
    Serial.println(incoming_data, HEX);
    delay(50);
  }
}

Could you post your code for the nRF52 that works with the above code, please? I can't get it to work with the esb_ptx example from SDK11.

[moso]

Nothing changed at nRF52 SDK11 "esb_low_power_ptx" example.

Thanks for the information, moso. Unfortunately it doesn't work for me.

Are you using the nRF24 with an Arduino or what?
