Advertising and Assigned Numbers

Artem Zemlyanukhin

Hello,

We need to add custom data to advertise packet. As I understand we can use Manufacturer Specific Data. But to do this we need to get our Manufacturer ID from Bluetooth SIG.

Bluetooth SIG provide a list of Assigned Numbers: www.bluetooth.com/.../generic-access-profile

Can we use values that are not used now for our purposes? For example 0xEE. Or it is not legal in case of mass production?

Best regards, Artem

    Hello Artem,

    BT SIG assigns Manufacturer Specific 16-bit IDs which are used inside Manufacturer Specific AD element (TAG = 0xFF). If you cannot get one (e.g. because you don't want to pay membership fees) you might use value 0xFFFF for testing (see suggestion inside the list). If you really want to ship product without being BT SIG member then I'm afraid you either:

    • need to find some agreement with any existing member to use his ID
    • or don't use Manufacturer Specific data at all
    • or break BT SIG GAP compliance and allocate some AD tag as you suggested. But again this is not allowed if you want to be completely in-line with GAP (which is kind of mandatory for GATT/ATT as well...)

    Cheers Jan
