Nordic_UART fails to pair Windows 8.1

[Lodge]

Hello, Has anyone managed to get the Nordic_UART software to pair in Windows 8.1? The heartrate monitor software pairs fine. Using show bluetooth devices, I can see the device, but when I click the pair button, it times out after a minute or so. I am using SDK 8.0.0. Thanks.

It seems to be getting an SM pairing failed, reason 0x08. The only difference in the logs I can see between hrs and uart is the Responder Key Distribution is 0x03 in the SM Pairing response for hrs and 0x00 for the uart

@Lodge: The nRF UART project doesn't use device manager to handle Bluetooth events but handles them directly in main.c The example doesn't support bonding but only pairing. No Long Term Key is distributed when bonding/pairing. I think it's the main reason it didn't work for you.

I modified the example to add bonding, could you try and let me know the result ? It only support one bonding, and no flash storage is used (erase bond after reset). Two modification added in sec_params_init() and on_ble_evt().
