HI all
How to test the hid transmission rate between DK board and PC？
Can you provide an example
Thank you.
HI all

Thank you.
Hi
Are you able to see what the application does before the USB is suspended? What device are you connecting the USB (J3 header on the DK) to on your device? Usually it's the USB host that suspends a USB device, so I would guess it is the PC you connect to that put the nRF into this state.
Best regards,
Simon

Hi Simonr
Thank you very much for your reply
I connected my DK board to my laptop. At this time, the laptop did not have a screen, but after 2-3 seconds of connecting, a suspend occurred
