EddystoneUid

  • Eddystone UID is broadcast by BLE beacons.

  • An Eddystone UID has a defined length of 16 bytes, consisting of a 10-byte namespace and a 6-byte instance.

  • You can create an Eddystone UID using a 16-byte hex ID string or separate hex strings for the namespace and instance.

  • Methods are available to retrieve the full hex ID, the namespace, and the instance as hex strings, and to convert a Message of type Message.MESSAGE_TYPE_EDDYSTONE_UID to an EddystoneUid.
