UUID needed..

[willwade]

I think we need to tweak something. I think we need to advertise with a UUID (reason being some code like in swift wont like it without a UUID)

• Its more standard to use a UUID
• Instead of a pairing packet. Use a predefined UUID.
• Its easier for a lot of different systems to look for a UUID than MAC address.

so maybbbe something like

const uint8_t custom_uuid[] = {
  0x12, 0x34, 0x56, 0x78, 0x9A, 0xBC, 0xDE, 0xF0, 
  0x12, 0x34, 0x56, 0x78, 0x9A, 0xBC, 0xDE, 0xF0
};

void update_advertisement_data() {  
  buttons_data.package_index = package_i;

  for(uint8_t i = 0; i < n_buttons; i++) {
    for(uint8_t j=3;j>0;j--) {
      buttons_data.button_packs[j][i] = buttons_data.button_packs[j-1][i];
    }
    buttons_data.button_packs[0][i] = button_packs[i];
  }
  
  Bluefruit.Advertising.clearData();
  Bluefruit.Advertising.addServiceUUID(custom_uuid);
  Bluefruit.Advertising.addManufacturerData(&buttons_data, sizeof(buttons_data));
}
