NUS Central on generic BLE USB Adapter

[Gabriele]

Hi,

I wanted to create a UART-like BLE channel between a desktop PC (central role) and nRF5340 (peripheral role).
On the nRF5340 side I setup Peripheral UART sample project which emulates a serial port using the Nordic UART Service (NUS).
On the PC side I have a C/C++ application running on Windows.

To enable the wireless communication I can rely on a generic BLE USB Adapter (e.g. USB-BT400).

I'm wondering if the NUS service, which is a custom GATT implementation by Nordic, is "standard" enough to allow easy integration through USB-BT400.

Hi,

The NUS service is a custom service, so it is not supported out of the box. You can make custom GATT clients though, so it should be possible to make a Windows specific implementation of this using Windows Bluetooth APIs. I do not have any experience with that, but there is some documentation here.
