List of company IDs for manufacturer specific data in BLE advertising . . . Where can I find the list of registered company IDs which are set right after the AD type field in an AD Structure in a BLE advertising packet when the AD type is 0xFF (Manufacturer Specific Data)? To be concrete, for example, how can I find the information telling that Apple's company ID is 0x4C00? (In an iBeacon packet, AD Type 0xFF is followed by 0x4C and 0x00 )
iBeacon Step-by-Step Complete Implementation Tutorial | Novel Bits The third is the company ID (registered with the SIG, 0x004C in the case of Apple), but in reverse byte order, since it needs to be in Little Endian format And then actual data which includes: Subtype, set to 0x02 which corresponds to iBeacon per Apple’s spec Subtype length (0x15) Next comes the user-defined fields These include:
ESP32 (32) – BLE, iBeacon – lucadentella. it Apple specifications further subdivide the AD data field in several elements: The first field is the manufacturer company; iBeacons normally use the code 0x004C, assigned to Apple Inc
ESP32 study notes (29) — BLE iBeacon broadcast AD Field Length: Length of Audio Data, indicating useful broadcast information Type of broadcast Company ID: The data field starts with a two byte company ID code SIG issues these ID codes to the company, 0x004C representing Apple id (only this ID is called iBeacon) iBeacon Type: byte 0x02 for this device is Beacon iBeacon Length: Length of remaining fields UUID: A standard 128-bit
rules for manufacturer specific advertisement data - Nordic Q A . . . Hello, Are there any rules for how to use the manufacturer specific ID in a beacon-format advertisement? For example: In this example: byte 0-2: 02 01 06 = flag for undirected unconnectable advertisement byte 3: 1A = length byte 4: FF = indicates "MANUFACTURER_SPECIFIC_DATA" byte 5-6: these two bytes are special company ID's registered with the SIG 004C (or 4C00) is for Apple byte 7 - end

Understanding the different types of BLE Beacons - Mbed 0x020106 defines the advertising packet as BLE General Discoverable and BR EDR high-speed incompatible Effectively it says this is only broadcasting, not connecting 0x1AFF says the following data is 26 bytes long and is Manufacturer Specific Data 0x004C is Apple’s Bluetooth Sig ID and is the part of this spec that makes it Apple-dependent
bluetooth_stack_features advertising advertising_manufacturer . . . - GitHub The general structure of advertising packets is described in Bluetooth Advertising Data Basics This example focuses on a Manufacturer-Specific Data (type 0xFF) as a specific advertising type Manufacturer-specific data can be used to add any custom data into advertising packets in any format suitable for your application For example, you could create a beacon that includes the reading of a
BLE Beacons: iBeacon, AltBeacon, URIBeacon, and derivatives 0x004C is Apples Bluetooth Sig ID and is the part of this spec that makes it apple dependent 0x02 is a secondary ID 0x15 defines the remaining length to be 21Bytes (16+2+2+1) The remaining fields are rather self-explanatory The proximity UUID is a standard 16byte 128bit BLE UUID The proximity UUID is typically unique to a company
