Puck.js Connect to Adafruit Feather Board

Thank you for the response - I've updated the puck.js code to include the "active:true" below, and I've included a full list of the devices that are seen by the puck.

setWatch(function(e) {

  NRF.findDevices(function(devices) {
    print(devices);
  }, {timeout : 2000,
      active : true, 
      filters : [
        { manufacturerData:{0x00D6:{}}}
      ]
     });
}, BTN, { edge: "falling", repeat: true, debounce: 50 });
