Change the puck UUID?

@Gordon - that didn't work. I had gotten to this point by using "save on send", so I enabled that again and used "var foo;" and was finally able to clear it out that way. I had even reloaded the boot code. Somehow that area of flash isn't getting cleared properly by any other method. I'd say there is a bug if I had to guess... I'd imagine this is going to cause others to have issues, so it bears looking into if you can do so. See attached screen grab.

Now, on to my task. I tried the following, but don't see the UUID/major, minor being advertised when I use my iBeacon scanners on the iPhone. It is based on the previously mentioned conversation:

var advertise = function(options) {
  var d = new Uint8Array([
    0x02, // Number of bytes after first AD structure
    0x01, // BLE_GAP_AD_TYPE_FLAGS
    0x04, // BLE_GAP_ADV_FLAG_BR_EDR_NOT_SUPPORTED
    0x1A, // Length
    0xFF, // BLE_GAP_AD_TYPE_MANUFACTURER_SPECIFIC_DA­TA
    0x4C, 0x00, // 0x004C == Apple
    0x02, 0x15, // iBeacon type + length
    0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,// iBeacon proximity uuid
    0x80, 0x00, // major
    0x34, 0xab, // minor
    0xc5]); // 2'c complement RSSI at 1 meter distance in dBm
  
  d.set(options.uuid,9);
  if (options.major!==undefined) d.set([options.major>>8,options.major],2­5);
  if (options.minor!==undefined) d.set([options.minor>>8,options.minor],2­7);
  if (options.rssi!==undefined) d.set([(options.rssi<0)?(options.rssi+25­6):options.rssi],29);
  
  var e = [].slice.call(d);
  NRF.setAdvertising(e, {interval:100});
};

advertise({
  uuid : [0xDA, 0xB5, 0x9C, 0x4F, 0xA4, 0xD6, 0xEE, 0x28, 0x6B, 0xFE, 0x8E, 0x00, 0x00, 0xBB, 0xC2, 0xBB], // ibeacon uuid
  major : 0x8000, // optional
  minor : 0x1234, // optional
  rssi : -59 // optional RSSI at 1 meter distance in dBm
});
