radio.begin() is not initializing

[Nikitanagar]

Hello,

I am working on LoRa-E5 mini with Arduino IDE(Connected LoRa-E5 mini with ST-Link/v2).
Here is the code:

// BSP : STM32 boards groups by STMicroelectronics 2.7.1
// Board select : STM Boards groups / LoRa boards
// Board part number : LoRa-E5 mini (Board to be selected from Tools submenu 'Board part number)

// 1. transmit data 12 bytes(Slave UID, millis(), Vbatt)
// 2. LED indication for transmission status

#include <RadioLib.h>           // 6.4.2  https://github.com/jgromes/RadioLib


#define SLAVE_UID   *((uint32_t*)0x1FFF7580)    
#define RADIOLIB_DEBUG_BASIC      (1)   // basic debugging (e.g. reporting GPIO timeouts or module not being found)
#define RADIOLIB_DEBUG_PROTOCOL   (1)


STM32WLx radio = new STM32WLx_Module();
static const uint32_t rfswitch_pins[] = {PA4, PA5, RADIOLIB_NC,RADIOLIB_NC,RADIOLIB_NC};
static const Module::RfSwitchMode_t rfswitch_table[] = {
  {STM32WLx::MODE_IDLE,  {LOW, LOW}},
  {STM32WLx::MODE_RX,    {HIGH, LOW}},
  {STM32WLx::MODE_TX_HP, {LOW, HIGH}},   // for LoRa-E5 mini  
  END_OF_MODE_TABLE,
};

#define dataNum 12                // data bytes
union unionData {                 // for data type conversion
  uint32_t dataBuff32[dataNum/4];
  int16_t  dataBuff16[dataNum/2];

};
union unionData ud;

uint32_t slaveuid = SLAVE_UID;    // Slave device UID
uint32_t ms;                      // timer [mS]
uint32_t us;                      // timer [uS]
char printBuff[4];                // for sprintf()
String txdata = "";               // transmission data packet string
bool transmittedFlag = false;     // flag that a packet was transmitted

void setup() {
  Serial.begin(115200);
  while(!Serial);
  delay(1000);
  Serial.println("**** Wakeup ****");

  // Pin initialization

  digitalWrite(PB5, LOW);     
  delay(1000);
  digitalWrite(PB5, HIGH);      
  delay(1000);

  // Radio initialization
  radio.setRfSwitchTable(rfswitch_pins, rfswitch_table);
  Serial.println("After RFSwitch Table");
  
  int state = radio.begin(922.0, 125.0, 7, 5, 0x12, 13, 8, 1.7, 0);
  Serial.println("state: ");
  Serial.println(state);

  if (state == RADIOLIB_ERR_NONE) {
    Serial.println("radio.begin() success!");
  }
  else {
    Serial.print("failed, code ");
    Serial.println(state);
    while(true) {
      digitalWrite(LED_RED, LOW);
      delay(100);
      digitalWrite(LED_RED, HIGH);
      delay(100);      
    }
  }

  // callback function when transmitted a packet
  radio.setDio1Action(setFlag);
}

void setFlag(void) {
  uint16_t irqstatus = radio.getIrqStatus();
  if(irqstatus == RADIOLIB_SX126X_IRQ_TX_DONE) {
    transmittedFlag = true;
  } else {
    transmittedFlag = false;
  }
}

void loop() {
  // Slave transmits data
  Serial.println("Transmitting packet ... ");

  ms = millis();
  us = micros();
  ud.dataBuff32[0] = slaveuid;    // Slave device UID
  ud.dataBuff32[1] = ms;          // mS timer

    sprintf(printBuff, "%02x", ud.dataBuff8[i]);

  // wait for transmission completion
  while(!transmittedFlag) {

  }

  // error status check
  if (state == RADIOLIB_ERR_NONE) {
    // packet was successfully sent
    Serial.println("transmission finished!");
    Serial.println();
  } else {
    // some other error occurred
    Serial.print("failed, code ");
    Serial.println(state);
  }

  delay(1000);  // Add a delay between transmissions (optional)
}

radio.begin() is not initializing.
Please help me to figure it out. Thank you in advance.

radio.begin() is not initializing.

What does that mean? Is there an error code? If so, which one? Or does something else happen?

Output:
**** Wakeup ****
After RFSwitch Table

Can you also try it with SPI debug enabled as described here? https://github.com/jgromes/RadioLib/wiki/Debug-mode

They way you have done it will not work, you can't just put the macros in your sketch.
