Driver error when trying to pair with Windows 10 computer

[grzegorz]

I'm writing code for PCA10040 basing on UART/NUS example. There are no big changes: different UUIDs and just one characteristic for both reading and writing. I can connect using nRF Master Control Panel without any problem. But I can't on Windows 10. The board is discovered but Windows can't pair with it. After pairing attempt there is status "Driver error". When I look a device manager there is an exclamation mark at my board. The status code is 10: This device cannot start. Additional code is STATUS_DEVICE_POWER_FAILURE. I have different board with ST's BlueNRG-MS BLE chip with exactly the same GATT services and it works perfectly with Windows 10. I tried to add static PIN but it didn't change anything. Windows doesn't even ask for PIN, it just fails during pairing.

My question is: what Windows 10 needs to pair? What should I add to BLE stack initialization?

EDIT: Some screenshots:

Nordic UART example ready to pair, paired and connected.

@grzegorz : Have you tried to use Master Control panel on the PC ? You would need a nRF5 dongle/DK to use it.

Note that the ble_app_nus doesn't support pairing, this could be the reason why windows 10 doesn't like it. You can try to test with the ble_app_proximity for example.

Note that Windows 10 natively doesn't know what to do with the ble_app_uart. You need an application on the PC to interact with the board.
