NRF52840DK USB HID example not sending data over USB

[ZGoode]

I am working on a project that involves creating a USB HID device.  I am trying to get the default sample included with the SDK to work, but it does not affect the mouse cursor or keyboard at all.  I have not edited the sample, and am trying to use the code as is just as a test.  My computer does recognize it as a HID device in device manager though.  I have verified that my board works as best I can, by using both the blink and button samples to verify functionality, both of which work fine.

One other thing of importance that I thought I should add, I have both the JLink USB and the NRF USB plugged into my computer.

Hello,

Sorry, I misinterpreted your words. I thought you were connecting both ports while flashing the program. Yes, what you said is true; you need to connect to the nRF USB port for testing the HID device applications. I am not sure about this zephyr sample, as I haven't tested it before. I will try to test it here. But can you try the⁠ nRF desktop sample from Nordic, where you have the option for both mouse and keyboard?

 

You can find the sample under ncs\v2.3.0\nrf\applications\nrf_desktop. For building and testing the sample, you can follow⁠ this blog. You need to use the specific configuration file for the keyboard; see this section. Also see the testing section for keyboards.

 

Kind Regards,

Abhijith
