BLE Advertisement Parser

Purpose

Use this tool to inspect raw BLE advertisement payloads captured from a sniffer or scanner, break them into individual AD structures, and decode the common types without doing it by hand.

Main steps

1. 1Paste the advertisement hex payload into the input box. Spaces, commas, or a continuous string are all accepted.
2. 2The parser walks the bytes as [Length | Type | Data] AD structures and decodes each one it recognizes: Flags, Local Name, Service UUIDs, TX Power, and Manufacturer Specific Data.
3. 3If the payload matches an iBeacon or Eddystone frame, the matching UUID, major/minor, TX power, or URL is extracted automatically.
4. 4Switch between the Structured, JSON, and C Struct tabs to see the same data in different forms, and copy or download whichever one you need.
5. 5Use the example button to load a sample iBeacon payload if you want to see the parser in action first.
