Bluetooth low energy API improvement request - managing and reading peripheral bonds

Question

We work with BLE programmers that as part of their API provide the ability to serialize, deserialize, and read the bond keys exchanged with a BLE peripheral when paired. This includes things like EDIV/RAND/LTK/CSRK/IRK. I would like to request an API in this namespace that brings the Windows Runtime API to the same level of functionality, at least on PC. Similar functionality is available on Linux, and most of the main BLE stacks (Apache mynewt/nimble, nordic softdevice, Mbed BLE, etc). Something along these lines:

interface IBleBondKeys
ulong CentralIdentityAddress
int CentralIdentityAddressType
ulong PeripheralIdentityAddress
int PeripheralIdentityAddressType
byte[] LongTermKey
ulong Random
ushort Ediv
byte[] IdentityResolvingKey
byte[] ConnectionSignatureKey
enum CapabilitiesAndKeyLengthFlags

Which could be added to a store for a specific BluetoothAdapter, and retrieved for a specific BluetoothDevice on that BluetoothAdapter.

Hi @EricP-8687 ,

Welcome to Microsoft Q&A!

interface IBleBondKeys
ulong CentralIdentityAddress
int CentralIdentityAddressType
ulong PeripheralIdentityAddress
int PeripheralIdentityAddressType
byte[] LongTermKey
ulong Random
ushort Ediv
byte[] IdentityResolvingKey
byte[] ConnectionSignatureKey
enum CapabilitiesAndKeyLengthFlags

I discussed these with the Bluetooth team, these information are protected from access on Windows and is unlikely to be made available via API for security reasons.

Thank you.
