Uncaught InternalError: BLE task completed that wasn't scheduled (3/4)

Yeah sorry, the first connect within the .on('Connect') was removed, actually the only one is the last on the bottom.
Just a question: is the event handler for the 'data' event called each time the Bangle receives something , correct?

Here is my final code:

Bluetooth.on('data', function(d) { 
  g.clear();
  g.setFont("Vector", 20);
  g.setColor(0,255,0);
  f = require("Storage").open(name, 'a');
  f.write(d + "\n");
  setTimeout(() => (g.drawString("Data", g.getWidth()/2, g.getHeight()/2)), 1000);
  setTimeout(()=>g.clear(),1500); 
  });

NRF.on('connect', function(addr) {
  g.clear();
  g.setFont("Vector",15);
  g.setColor(255,0,0);
  g.drawString(addr,g.getWidth()/2, g.getHeight()/2);
  g.setFont("Vector",25);
  setTimeout(()=>g.drawString("Connected", g.getWidth()/2, g.getHeight()/2), 500);
  setTimeout(()=>g.clear(),1000); 
  E.setConsole(null);
});

NRF.on('disconnect', function(reason) {
  g.clear();
  g.setColor(0,0,255);
  g.drawString("Disconnected", g.getWidth()/2, g.getHeight()/2);
  setTimeout(()=> g.clear(), 1000);
});

// Code

g.setFontAlign(0,0); 
g.setFont("Vector",25);
delay = 5000;

name = "MyFile";

setInterval(function(){console.log(E.getTemperature());}, 1000);

The thing is that when I send something from my laptop, bangle does not seem to receive it.
