NuS (Nordic Uart Service) windows example?

[duaneql]

My Win10 app - needs to connect to an NRF52 that is using the "NuS" Service - and I can't use the WinRT or dotNET.

In this post:  https://devzone.nordicsemi.com/f/nordic-q-a/49090/looking-for-a-pc-ble-dongle-that-supports-nordic-uart-service

The suggestion is to use a usb-ble dongle

My laptop has a BLE interface, I'd like to use the existing windows BLE interface to talk to the nrf52 running the NuS service.

I can't find examples for this on Windows - i can find Android examples, and IoS examples - but no win 10 examlples.

The reply from Joakim is to look at the Windows BLE Explorer ... which is a Windows App Store ...

These things are not command line tool friendly, and require a huge overhead that won't link with my existing codebase

What I'm looking for is a DLL or something - that can do four things:

1) Scan for existing NUS devices providing a list

2) connect to one of those - ie: open() or connect()

3) Let me read and write the tx/rx characteristics, ie:  read() and write()

4) Disconnect, ie: close() or disconnect()

It would be great if this was in C and worked directly with devices running the NuS service.

Thanks

Even a C# console app example that is very simple would be helpful, or a UWP ... 

something that is command line utility like - not a GUI type application.

Hi,

Our PC applications (nRF connect & pc-ble-driver) rely on an external dongle/dev kit programmed with our Bluetooth stack (Softdevice). We don't have any examples that work with the native BT stack on Windows, unfortunately.

I have little experience in creating windows applications, so not sure if I can give you any good recommendations. Maybe you can consider Noble (https://github.com/noble/noble) as an alternative. I don't think you need to be an experienced Javascript programmer to modify the existing examples to expose the functionality you want.

I need something I can call from C or C++ - Javascript (nodeJS) as far as I know - is not callable from C/C++ - and if it is, the process to do so would be horrendous.

Hi,

I don't know if I understand well if I want to do communication PC and nrf (NUS) I need to connect nordic devkit on PC side? Could I use simple/standard BLE dongle?

I prepared nrf with NUS and I used BlueZ to read/write NUS characteristics and it work well. Do you have any tools on linux to set connection between PC and nrf? For example PC script which emulate /dev/ttyXX device.

I read it infocenter.nordicsemi.com/index.jsp

But here I need Nordic devkit on PC side, right? Could you tell me if nordic offers usb BLE dongles  that I can replace devkits?

With Bluez as the host, you can use a regular BLE dongle, or built-in BLE HW if your PC has it. This does not require a Nordic development kit. But we currently don't have any PC apps that interface with Bluez, only the Softdevice (nordic bt stack).  Maybe Noble (https://github.com/noble/noble) or Bleak (https://github.com/hbldh/bleak) could be an option for you.
