What is your problem?

When scanning for BLE devices we receive a map containing all advertisement data (ScanResult.AdvertisementData.ManufacturerData).

I assumed the keys in this map correspond to the BLE standard keys (https://www.bluetooth.com/wp-content/uploads/Files/Specification/Assigned_Numbers.pdf?id=3).

For instance Manufacturer Specific Data has the Flag 0xFF (dec:255) but I am receiving key 0xAB (dec:171) instead.

Is this an error or am I misinterpreting the meaning of the key? If so, what is the meaning of the key? Is the data provided in ScanResult.AdvertisementData.ManufacturerData already only the data marked with the 0xFF Flag? If so, can we somehow get access to the full list of advertisement data somehow?
