This is my send and receive code in STM32 (blue board). But i can't send and receive data . why? I did use Enrf24.h . Enrf24 link: https://github.com/spirilis/Enrf24 send code is:

#include <SPI.h>
#include <Enrf24.h>
#include <nRF24L01.h>
#include <string.h>
#define ce_nrf PB12
#define csn_nrf PB13
#define irq_nrf PA0
Enrf24 radio(ce_nrf, csn_nrf, irq_nrf);  // P2.0=CE, P2.1=CSN, P2.2=IRQ
const uint8_t txaddr[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0x01 };
void setup() {
  Serial.begin(9600);
  SPI.begin();
  SPI.setDataMode(SPI_MODE0);
  SPI.setBitOrder(MSBFIRST);
  radio.begin();  // Defaults 1Mbps, channel 0, max TX power
  radio.setTXaddress((void*)txaddr);
}

void loop() {
  Serial.print("Sending packet: ");
  radio.print("OONN");
  radio.flush();  // Force transmit (don't wait for any more data)
  delay(1000);
  Serial.print("Sending packet: ");
  radio.print("OOFF");
  radio.flush();
  delay(1000);
}

receive code is:

#include <SPI.h>
#include <Enrf24.h>
#include <nRF24L01.h>
#define ce_nrf PB12
#define csn_nrf PB13
#define irq_nrf PA0
Enrf24 radio(ce_nrf, csn_nrf, irq_nrf);  // P2.0=CE, P2.1=CSN, P2.2=IRQ
const uint8_t rxaddr[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0x01 };
const char *str_on = "ON";
const char *str_off = "OFF";
void dump_radio_status_to_serialport(uint8_t);
void setup() {
  Serial.begin(9600);
  SPI.begin();
  SPI.setDataMode(SPI_MODE0);
  SPI.setBitOrder(MSBFIRST);
  radio.begin();  // Defaults 1Mbps, channel 0, max TX power
  radio.setRXaddress((void*)rxaddr);
  radio.enableRX();  // Start listening
}

void loop() {
  char inbuf[33];
  while (!radio.available(true));
  if (radio.read(inbuf)) {
    Serial.print("Received packet: ");
    Serial.println(inbuf);
