Uwb dwm3001cdk with adaptor

Hi everyone,
I have two Qorvo CDK3001DWM devices. They work fine when connected to a PC via USB. However, when I unplug them from the computer and connect them to a regular USB power adapter (5V, 2A), they don’t power on or seem to work at all.

I have a few questions regarding this:

  1. Do these devices require only power via USB, or do they also need data communication with the PC to function?
  2. Is there any special setting or hardware modification required to run them from just a power adapter?
  3. My goal is to run these devices without a computer—just by plugging them into a wall socket using a USB adapter. Is this possible? like this video https://www.youtube.com/watch?v=DFp52BzD1WA&ab_channel=KevinVincentTan

If anyone has experience with this or suggestions, I’d really appreciate your help.
Thanks in advance!

Hi @Haktan!

This is a known issue, the problem and a workaround are detailed here:

Replying to your questions, no USB data required, you can use the CLI commands to define the starting app and power it as you prefer, but, as you experienced, the implementation has an issue. If you apply the fix, you can use it as shown in the video.

Kind regards!
