Digital stethoscope

[benzedira_yasmine]

So I'm making a digital stethoscope using arduino and microphone max9814 and bleutooth HC _05
And I need and app to receive value and chart
I'm using this code :
#include <SoftwareSerial.h>

int SoundSensor=A0;
int LED13=13;
int Signal;
int Threshold=250;
int S;

SoftwareSerial mySerial (0,1);

void setup()
{
pinMode(LED13,OUTPUT);
Serial.begin(9600);
}

void loop ()
{
Signal = analogRead(SoundSensor);
S=(Signal/8);
Serial.print("Your heart beat is: ");
Serial.println(S);
mySerial.println(S);
if(Signal > Threshold)
{
digitalWrite(LED13, HIGH);
}
else
{
digitalWrite(LED13, LOW);
}
delay(1000);
}
I tried to do bleutooth block but it never show the bleutooth to connect

You need to ask for permission before scanning for devices.

Runtime error when using (Lỗi runtime khi sử dụng) BluetoothClient

(Canned Response)
These blocks can be dragged into your Blocks Editor to request permission(s) for Bluetooth scanning and connecting. All three parts are needed.

Thanks to @Anke for the original code.
My changes include

• use of the Screen1 permission blocks to avoid the possibility of a typo
• using a TinyDB tag particular to BT permissions and only for BT permissions.
