I have built a ESP software relying on Arduino components to activate the LORA configuration github code

For that, I have moved my main.c to main.cpp and updated all make files accordingly, my code compiles without any error. but the execution of the app main is so weird and can’t figure out what is the cause!

main function:

extern "C" void app_main(void)
{
   fflush(stdout);
   printf("IM heren");
   fflush(stdout);
   lora_arduino();
}

while lora arduino function

void lora_arduino() {
  fflush(stdout);
  printf("hereeeeee0211111111n");
  fflush(stdout);
  setup();
  printf("hereeeeee0n");

  if (e220ttl.available()>1) {
      Serial.println("Message received!");
      // read the String message
    ResponseContainer rc = e220ttl.receiveMessage();
      // Is something goes wrong print error
     if (rc.status.code!=1){
        Serial.println(rc.status.getResponseDescription());
     }else{
        // Print the data received
        Serial.println(rc.status.getResponseDescription());
        Serial.println(rc.data);
        printf("hereeeeeen");
        // printf('received data is %s', rc.data);
     }
 }

printf("hereeeeee1010101--------");
}

output:

None of my prints are getting printed. what is wrong with code not to be printed at least?
