iBeacon UUID

In order for Apple iOS apps to pick up geo.88.io iBeacon signals, you must program all those iBeacons with the same UUID:

f349d869-ce7c-5e04-a44d-99d9ad2c8e4d

It is the UUID v5 of the DNS Domain geo.88.io

Major and Minor numbers are application specific please refer to the guidelines for your application.

According to Apple iBeacon specs
BLE_GAP_ADV_TYPE_ADV_NONCONN_IND
is supposed to use so avoid SCAN_RSP tricks if possible.
