Namespace (10 bytes hex)

Instance (6 bytes hex)

Calibrated TX Power:

URL Scheme

URL (after scheme prefix)

Max 17 bytes after encoding (.com, .org, .edu are compressed)

TX Power:

Temperature (C)

Adv PDU Count

Sec Count (0.1s units)

iBeacon is Apple's beacon protocol. Uses a 16-byte proximity UUID, 2-byte major, and 2-byte minor for identification.

The advertising packet includes Apple's company ID (0x004C) and a fixed iBeacon prefix (0x0215).

Eddystone-UID broadcasts a 10-byte namespace and 6-byte instance for unique beacon identification.

Uses the Eddystone service UUID (0xFEAA) and frame type 0x00.

Eddystone-URL broadcasts a compressed URL that devices can open. Limited to ~17 bytes of encoded URL data.

Common suffixes (.com, .org, .edu) are compressed to single bytes.

Eddystone-TLM broadcasts telemetry data: battery voltage, temperature, advertising count, and uptime.

Used alongside UID/URL frames to monitor beacon health.
