title: List of company IDs for manufacturer specific data in BLE advertising packets
body: <p>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)?</p>
  
  <p>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.)</p>
