Doubts related to registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\BTHPORT\Parameters\Devices

Hi!

I want to gather some information about bluetooth devices paired to my laptop. I saw that registry key that storage some useful info:

126745-2021-08-26-11-49-54-editor-del-registro.png

But i'm facing some issues trying to understand this information, for example:

  • There is no documentation related to this values so i can't know exactly what is stored there.

  • The values LastConnected/LastSeen never got updated. I connected several times trying to get those values updated but they remain the same keeping the date of when i paired the device.

  • I don't know how LEAddressType is encoded, i know there is four different types for BLE addresses but i don't know how to match this value to those types.

I hope someone can help me. My best wishes,

Sergio.

Hello @Serruitec-3372 ,

there is not much information indeed but here you have the ones for Scanning parametrization:
