B4R Question Passing a variable to #If c

[yaqoob]

Hello Everyone,
I am using the following code to stream an MP3 file from the server. The code works if I hardcode the music URL in the #if C script. I tried to pass the URL from B4R as RunNative("setup", URL) and change the code to
file = new AudioFileSourceHTTPStream (b4r_main::_url);
It did not work. I appreciate any help. I appreciate any help you can provide.

Sub Process_Globals
    Public url as String
    
End Sub

Public Sub Setup
    
    
    
    RunNative("setup",url)
    
End Sub


#if c

#include "M5Atom.h"
#include <WiFi.h>
#include "SPIFFS.h"
#include "AudioFileSourceHTTPStream.h"
#include "AudioFileSourceBuffer.h"
#include "AudioGeneratorMP3.h"
#include "AudioOutputI2S.h"


AudioGeneratorMP3 *mp3;
AudioFileSourceHTTPStream *file;
AudioFileSourceBuffer *buff;
AudioOutputI2S *out;


//const char * url = "http://192.168.0.6:51042/Basyra%20BCam0004%20Image.mp3";



void setup(B4R::Object* M )
{
  M5.begin();
// Serial.printf("this url\n");
//Serial.printf(b4r_main::_url);

   Serial.printf("I am in setup\n");
  file = new AudioFileSourceHTTPStream(b4r_main::_url);
  // Create a buffer using that stream
  buff = new AudioFileSourceBuffer( file, 4096 );
 

  out = new AudioOutputI2S();
    out->SetPinout(22, 21, 25);
    
 mp3 = new AudioGeneratorMP3();
  // Pass in the *buffer*, not the *http stream* to enable buffering
  mp3->begin(buff, out);
}


void play(B4R::Object*)
{
 
  if (mp3->isRunning()) {
    if (!mp3->loop()) mp3->stop();
  } else {
    Serial.printf("MP3 done\n");
     b4r_main::_playfinished=1;
    delay(10);
  }
}

#End If
