  Thanks, that seems to do the job!
  Might be worth noting, though, that it doesn't appear to work every time - sometimes the connection can drop out, and no close event is fired. When this happens, the "Disconnected (gattserverdisconnected)" log does not appear in the console from puck.js either.

  If a puck disconnects from my browser due to the connection dropping out (e.g. it moves out of range) is there a way to detect this on the web front end? I can see that puck.js creates the following console log:
  Disconnected (gattserverdisconnected)

  I’m using the following code snippet to create a 2-way connection as per one of your site tutorials. This includes the part about resetting the puck on disconnection, which seems to work fine on the puck - I just want to be able to reset the browser too.

  Puck.connect(function(connection) { 
  	connection.on("data", function(d) { 
  		// handle receiving data 
  	} 
  	connection.write("reset();\n", function() { 
  		setTimeout(function(){ 
  			// do various stuff here 
  			// reset on disconnect 
  			connection.write("NRF.on('disconnect',function(){ reset(); });\n",function(){}); 
  		},1500); 
  	}); 
  	// I'm hoping there's a way to detect disconnection here 
  	// e.g. connection.on("disconnect", function(){}); 
  }); 
  

  Thanks!

  Never mind - looks like I needed a firmware update! All good now :)

  Thank both, that's very helpful! I have got the first 2 working, but I think I'm using NRF.getAddress() wrong, as I'm getting the following error: "Uncaught Error: Function "getAddress" not found!"

  My code is as follows:

  Bluetooth.println('BOARD:'+process.env.BOARD); // works
  Bluetooth.println('SERIAL:'+getSerial()); // works
  Bluetooth.println('MAC:'+NRF.getAddress()); // does not work
  

  Am I doing anything obviously wrong? Does NRF need to be used differently?

  Hello, I've just been playing with a Puck.js for the first time, and I must say, it's quite incredible!

  I was just wondering if there's a way to retrieve the device name and ID once it's connected in the browser, as js vars. I see that these appear as console logs, upon connection, but I can't find a way to access them. Is there a general "get device info" function or something?

  I've been successfully working with button clicks, LEDs, light, temperature and magnet sensing, but am failing to find any documentation for this, although it seems like something that'd be essential for dynamically working with multiple devices. Thank you!
