  I was reading about these x27.168 automotive stepper motor gauges and noticed that adafruit suggests that you may be able to drive directly from a microcontroller (allowing for the appropriate kickback diodes.)

  Would anybody know if its possible to do directly from the puck.js?

  Thanks for your help Gordon. This is a nice little example to do with the puck by itself.
  For anyone else, finished code to be used along with the adafruit bluefruit app is below.

  NRF.on('connect', function(addr) { 
    LoopbackA.setConsole();
  });
  
  setWatch(function() {
    Bluetooth.setConsole();
  }, BTN, {repeat:true, edge:"rising", debounce:50});
  
  
  Bluetooth.on('data', function(d) { 
    if (d[0]=="!" && d[1]=="B") {
      var b = d.substr(2,2);
      if (b[0]=="1") LED1.write(0|b[1]);
      if (b[0]=="2") LED2.write(0|b[1]);
      if (b[0]=="3") LED3.write(0|b[1]);
      if (b[0]=="4") digitalWrite([LED1, LED2, LED3], b[1]*7);
    }
  });
  

  Just remeber to press the btn on the puck if you want to send some new code to the puck

  How can I detect once a connection has estabilished then run a LoopbackA.setConsole().
  I thinking it should automatically switch to LoopbackA.setConsole() then press the button on the puck to return to Bluetooth.setConsole(). I tried the following but it didn't work and I'm assuming it has something to do with switching to LoopbackA.setConsole() before a Bluetooth connection has been established.

  LoopbackA.setConsole(1);
  
  setWatch(function() {
    Bluetooth.setConsole();
  }, BTN, {repeat:true, edge:"rising", debounce:50});
  
  
  Bluetooth.on('data', function(d) { 
    if (d[0]=="!" && d[1]=="B") {
      var b = d.substr(2,2);
      if (b[0]=="1") LED1.write(0|b[1]);
      if (b[0]=="2") LED2.write(0|b[1]);
      if (b[0]=="3") LED3.write(0|b[1]);
    }
  });

  I get it now thanks @Gordon and sorry @Wilberforce you were correct.
  Gordon you're correct, copy and pasting does allow it to be sent as one packet.

  I can't do that because the puck will go back to being on Bluetooth instead of being in LoopbackA.

  Excellent explanation! Thank you for explaining the LoopBack to me, I was really scratching my head over how to stop the JS interpreter intercepting incoming data.

  It works really well with the app, however, I tried to use the WebIDE to pass a command string instead of using the app.
  When I press the button on the puck to activate the LoopBackA the WebIDE console locks up, the console logs -> LookbackA then it does not let me type anymore.

  The adafruit Bluefruit has a control pad the sends strings such as: !B41CRC
  I want to parse this into its component parts such as: [‘!’] [‘B’] [‘4’] [‘1’] [CRC]
  I think I can do this, but I don't know how to set a watch event that actually parses the string once it's received.
  It is not like the bluefruit app calls a function parse(!B41CRC). How do I watch for incoming data then do something with it?
