Software example for USB communication with a PC

[Alessio]

Hi,

looking for some examples I found this ticket but links inside seem not working.
https://devzone.nordicsemi.com/f/nordic-q-a/146/example-software-for-usb-communication-of-nrf24lu1p

I was looking for some example on how to interface a PC software with the USB dongle nRF24LU1P.
I'm trying to interface using winusbnet on a WPF application.
Thanks.

Hi Alessio

Any particular reason you are using the nRF24LU1+, and not one of our newer parts such as the nRF52840 or the nRF52833?

The nRF24L series is very old at this point, and is not recommended for new designs. 

In the mean time I will check if we are able to dig out some of the old examples for the nRF24LU1+.  

Best regards

Hi Torbjørn

We've choose the nRF24 because it's not based on Bluetooth. Once nRF24 is configured, after switching devices on it just work . With Bluetooth there are compatibility issues, pairing procedures and so on.

Hi Alessio

The nRF52 series includes a multi protocol radio and is not limited to Bluetooth only. 

If you are establishing communication between Nordic devices, and not smart phones, PC's etc, you can run a library called nrf_esb, which configures the radio to use the Enhanced Shockburst protocol. This is the same protocol used in the nRF24L series, but ported to run on the newer devices. 

I did some checking on what kind of software support we provide for the older parts, but unfortunately since these parts are deprecated we no longer make the examples available. 

Best regards

Regarding the main topic, the actual problem is at driver level where we're trying to prepare a inf file for deploing a winusb driver. But it doesn't work. If you have some example or guide on how to deploy USB driver even for similar devices I think it will help.

Thanks.

Hi Alessio

You could have a look at an old snifferdemo that I made for the LU1+ back in the day:
https://github.com/NordicPlayground/nrf24lu1p-snifferdemo

It uses the Winusb/libusb driver, and the inf file is included in the repo. 

As far as I remember it was possible to manually edit the .inf file to allow you to change the PID/VID etc. 

Best regards
