iBeacon Demo - what UUID?

[danshev]

1. As written, what UUID is the iBeacon demo using? I'd like to see if iOS can detect it
2. How can we change the UUID / major / minor values that the device is broadcasting?

Hi @danshev,

1. The broadcasting UUID in the iBeacon demo is just for demonstration. If you want to make your Duo discovered as iBeacon, simply change the UUID in the advertising data to be :
   e2 c5 6d b5 df fb 48 d2 b0 60 d0 f5 a7 10 96 e0
2. We add detailed comment in the advertising data array, just change the corresponding line in the array:

// iBeacon advertising data
static uint8_t adv_data[31] = {
  0x02,
  BLE_GAP_AD_TYPE_FLAGS,
  BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE, 

  0x1A,
  BLE_GAP_AD_TYPE_MANUFACTURER_SPECIFIC_DATA,
  0x4C,0x00,    // Company Identifier Code = Apple
  0x02,         // Type = iBeacon
  0x15,         // Following data length
  0x71,0x3d,0x00,0x00,0x50,0x3e,0x4c,0x75,0xba,0x94,0x31,0x48,0xf1,0x8d,0x94,0x1e, // Beacon UUID
  0x00,0x00,    // Major
  0x00,0x00,    // Minor
  0xC5          // Measure Power
};

Kind regards
