unable to retrive lorawan devEui

[naveen-79]

unable to retrive devEui set using setDevEui.

#include <STM32LoRaWAN.h>

STM32LoRaWAN modem;

String appEUI_Set = "7649FC09A028FE04";
String devEUI_Set = "9A0684E16B882E92";
String appKey_Set = "E236B8E7D41F0B8966285798925BA7A6";

void setup() {
  Serial.begin(115200);
  pinMode(LED_BUILTIN, OUTPUT);

  modem.begin(IN865);

  // Set LoRaWAN credentials
  if (modem.setDevEui(devEUI_Set)) {
    Serial.println("DevEUI successfully set!");
  } else {
    Serial.println("Failed to set DevEUI!");
  }
  modem.setAppEui(appEUI_Set);
  modem.setAppKey(appKey_Set);

  // Attempt to join OTAA
  // if (modem.joinOTAA()) {
  //   Serial.println("Join OTAA success!");
  // } else {
  //   Serial.println("Join OTAA failed!");
  // }

  delay(1000);

  String devEUI;
  modem.getDevEui(&devEUI);
  Serial.print("DevEUI: ");
  Serial.println(devEUI);
}

void loop() {
  digitalToggle(LED_BUILTIN);
  delay(1000);
}

OUTPUT

DevEUI successfully set!
DevEUI: B1C4E90005012038

expected output 9A0684E16B882E92. got B1C4E90005012038

Hi @naveen-79
You're right, the DevEUI is well set but when retrieve it is not correct.
I've dig inside the code and it seems there is an issue with the DevEUI fields in a structure which is not allocated. So the value you retrieve is not correct.

Please, Could you file an issue here: https://github.com/stm32duino/STM32LoRaWAN/issues?
