问题 I'm trying to create an iOS app that will read from an OBDII Bluetooth 4 (LE) device. I purchased a Vgate icar3 bluetooth(4.0) elm327 OBDII. I plug it into my car and find IOS-VLink peripheral that advertises some services. I can then get the characteristics for those services. These are the services I find: <CBService: 0x1780729c0, isPrimary = YES, UUID = Battery> <CBService: 0x178072a80, isPrimary = YES, UUID = 1803> <CBService: 0x178072ac0, isPrimary = YES, UUID = 1802> <CBService:

问题 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.) 回答1: The list of two-byte Bluetooth company identifiers, sometimes called the CIC, can be found here: https://www.bluetooth.com
