I am using bluetooth serial plugin for this.I can pair with device successfully.
sendData(){

this.bluetoothSerial.write("Hello world").then((data)=>{
  
      alert(data+'for success writing data');
  },err=>{
      alert(err+'for error writing data');
 

});

}

It shows the success message
But I wanted to know where actually it stored on paired device

Well principal you have only to fire this https://github.com/don/BluetoothSerial#read or https://github.com/don/BluetoothSerial#subscribe

But by the way I never used this plugin. :wink:
I guess it is also better for you to get better answers that you ask via the “issues” on github. https://github.com/don/BluetoothSerial/issues

I am also getting the sucess ok message but the other paired device hasnt yet received the data I sent and neither am I able to find the location of the data. Has anybody able to get a solution to that?
