want nrf24l01 communication with nrf51822

[pallavi]

hello,will you please tell me which code i have to use in the sdk 12.2.0 for rf communication with nrf51822 and nrf24l01 .and also tell me which settings i have to do for nrf24l01 side as a transmitter.so that i can receive data on nrf51822 side.

hello sir, these are the details aftyer executing printDetails(); function

STATUS		 = 0x0e RX_DR=0 TX_DS=0 MAX_RT=0 RX_P_NO=7 TX_FULL=0
RX_ADDR_P0-1	 = 0xe7e7e7e7e7 0xc2c2c2c2c2
RX_ADDR_P2-5	 = 0xc3 0xc4 0xc5 0xc6
TX_ADDR		 = 0xe7e7e7e7e7
RX_PW_P0-6	 = 0x01 0x00 0x00 0x00 0x00 0x00
EN_AA		 = 0x3f
EN_RXADDR	 = 0x03
RF_CH		 = 0x4c
RF_SETUP	 = 0x0f
CONFIG		 = 0x0e
DYNPD/FEATURE	 = 0x3f 0x06
Data Rate	 = 2MBPS
Model		 = nRF24L01+
CRC Length	 = 16 bits
PA Power	 = PA_MAX

sir i have also tried radio example for nrf51822 nrf\nRF5_SDK_12.3.0_d7731ad\nRF5_SDK_12.3.0_d7731ad\examples\peripheral\radio\receiver\pca10028\blank\arm4 on the arduino side i have done these settings,

#include <SPI.h>
#include <nRF24L01.h>
#include <RF24.h>
#include "printf.h"      // General includes for radio and audio lib

RF24 radio(18, 19);
unsigned char values;
int x=0;
//const byte rxAddr[6] = "00001";
const byte rxAddr[5] = {0xC0, 0x01, 0x23, 0x45, 0x67};
//char values;
void setup()
{
  Serial.begin(9600);
  printf_begin();  
  radio.begin();
  radio.openWritingPipe(rxAddr);
  radio.setChannel(7);
 //radio.setPALevel(RF24_PA_MAX);
  radio.setDataRate(RF24_1MBPS);
 // radio.setChannel(7);
//  radio.setRetries(15,15);
   radio.setCRCLength(RF24_CRC_16);
   radio.setPayloadSize(1);
 //radio.enableAckPayload();
// radio.enableDynamicPayloads();
 //radio.openWritingPipe(rxAddr);
  radio.stopListening();
//radio.printDetails();
}

void loop()
{
//  Serial.print("value");
 // if(Serial.available()) {    
    
  //   while (Serial.available()>0){
        
       values = '1';
        
         radio.write(&values,32);
         delay(500);
      //  Serial.print(value);  //prints the character just read
     }
     
           
    //Serial.println();

in this case i am able to make radio communication betrween nrf24l01 and nrf51822.but in nrf51822 side i am not able to take transmitted character it shows nrflog as data received is 0.

can you please tell me if there is any settings of setting payload on transmission and recveiver side.

hello sir, i am waiting for your reply.as i am stucked with this problem... Pallavi.

Hi
Since I don't have the Arduino stuff up and running I had to dig out some old code to control the nRF24L01+ module from a Nordic kit.

I used the following code to configure the L01+ module:

static void l01_configure(void)
{
    l01_config_t l01_config = {1, 11, 12, 13, 14, 15, 16};
    hal_nrf_nrf52_init(&my_l01, &l01_config, l01_irq);
    
    nrf_delay_us(1500);
    
    hal_nrf_set_power_mode(HAL_NRF_PWR_UP);
        
    nrf_delay_us(1500);
		
    hal_nrf_set_crc_mode(HAL_NRF_CRC_16BIT);
    
    hal_nrf_set_datarate(HAL_NRF_2MBPS);
    
    hal_nrf_setup_dynamic_payload(0x3F);
    hal_nrf_enable_dynamic_payload(true);
}

The register readout after configuration was the following:

APP:INFO:  Reg 0x00: 0x0E
APP:INFO:  Reg 0x01: 0x3F
APP:INFO:  Reg 0x02: 0x03

APP:INFO:  Reg 0x0E: 0xC5
APP:INFO:  Reg 0x0F: 0xC6
APP:INFO:  Reg 0x10: 0xE7-0xE7-0xE7-0xE7-0xE7
APP:INFO:  Reg 0x11: 0x00

APP:INFO:  Reg 0x17: 0x21
APP:INFO:  Reg 0x18: 0x00
APP:INFO:  Reg 0x19: 0x00
APP:INFO:  Reg 0x1A: 0x00
APP:INFO:  Reg 0x1B: 0x00
APP:INFO:  Reg 0x1C: 0x3F
APP:INFO:  Reg 0x1D: 0x04

With this configuration I could send packets to an nRF51822 device, running the standard esb_prx example in the SDK.

Do you have two nRF51 boards?
If so I can probably share my code, and you can try to run the nRF24L01+ module straight from the Nordic DK and see if you can get that to work.

hello sir, i have two nrf51 bords. but in one side i am using arduino with nrf24l01 and on the other side nrf51 board.then if you have the code please share.i am stuccked here badly.i want this communication for further implimentation of project on nrf51.

Thank you , Pallavi
