OOB secure connection

[arikramon]

Hi

We are using nRF52832 with SDK17.2 and SD 112.

We are trying to make a NFC_PAIRING_MODE_GENERIC_OOB  to a PC with the following System Information:

       OS: Windows 10

       DotNet Framework Version: 4.5.2

       Product: Visual Studio 2015

       Languagae: C#

       Namespce: Windows.Devices.Bluetooth

We are using the class BluetoothLEDevice in our system.

Currently we succeed to connect to BLE devices with "NFC_PAIRING_MODE_JUST_WORKS" pairing.

We were unable to connect to BLE devices with "Out Of Band" pairing.

Is there a way to do it with the DotNet ?

If not is there another library that can be used on the PC side to support this mode?

Thanks

Arik

Hi Arik, 
Could you describe what exactly occurred when you tested? 

Do you have NFC reader on your PC ? 

Did you managed to get it work with passkey/numeric comparison ?

With just connect every thing is working OK.

The problem is on the windows side: which dot net library to use, which supports OOB connection

Hi Arik, 
We unfortunately don't have much experience with the Bluetooth library on Windows. We don't have any example on OOB with the library. 
I did a quick search and it seems that you need to prepare the temporary key (OOB key) in the BLE pre-pairing data. It's described here.

I would suggest you to seek help on this topic from Microsoft support channel.
