Windows 10 UWP (C#) and nRF52840 CDC USB

[Sebastor]

Hi,

I'm trying to make connection between nRF52840 dongle programmed with "examples/peripheral/cli" application and Windows 10 UWP "CustomSerialDeviceAccess" example code which is a part of Microsoft examples collection https://github.com/Microsoft/Windows-universal-samples/archive/master.zip. I use SDK 15.2, installed drivers for dongle from "examples/usbdrivers". Dongle is available in the device manager as nRF52 USB CDC Demo. I can communicate with dongle from TeraTerm application.

The nRF52840 dongle can be connected from UWP Windows app but, I cannot send or receive any data. Does anybody has working demo code for Windows 10 UWP and nRF52 usb dongle ?

I'm gonna use the app under Windows 10 IoT (Raspberry Pi).

I was trying the same with "CustomUsbDeviceAccess" another demo app from Microsoft collection, but the dongle is not even available to connect.

Regards

Hi,

 

Could this be the same issue as you're seeing?

https://github.com/Microsoft/Windows-universal-samples/issues/1052

 

Have you checked other issues to see if any of them match the behavior you're seeing?

Kind regards,

None of these issues match to behavior I'm seeing. As I mentioned I can read/write to nRF52840 dongle from apps like TeraTerm or Putty. The problem is when I'm trying to connect to UWP app (to run it eventually on RaspberryPi). On the other hand I have no problem to connect UWP app and FTDI devices.

Do I need different USB CDC driver for Windows 10 IoT ?

Hi,

 

I'd recommend that you open an issue on their github site and ask. As the dongle works in different terminals, the issue must be related to the c# application somehow.

Kind regards,

In case some one has this issue:

You need to set : the Baud Rate/ Read timeout/ Write timeout, and the important one (especially to communicate over the CDC ACM) the DTR (Data Terminal Ready), you need to make sure this option is enabled.
