DWM3001CDK not detected qorvo-one GUI

Wireless Connectivity Ultra-Wideband

I have a qorvo DWM3001CDK and have downloaded the DW3_QM33_SDK_1.0.2 SDK that comes with it.
I’ve followed all the instructions in the DWM3001CDK quick start guide, i.e i have flashed DWM3001CDK-DW3_QM33_SDK_UCI-FreeRTOS.hex on the board .
After this i tried the Qorvo One TWR GUI evaluation tool, and i couldn’t see my board there .

My leading theory is that i need a QM33120WDK1 for it to work .

Is there a way where i can perform TDOA based localisation using just the DWM3001CDK(multiple)???

@Ansh_semwal , DWM3001CDK has 2 USB ports. The one further from the antenna is meant for programming and the one closer to the antenna is meant for communication. Please make sure you have it connected to this second one if you wish to use it with the GUI. You will need 2+ CDK boards to be able to do TWR in the GUI.

For TDoA, it is possible but Qorvo does not provide software to do this out of the box. If you are interested in TDoA, I would recommend taking a look at @leapslabs new UDK1 kit found here: https://www.leapslabs.com/products which demonstrates TDoA out of the box and the kit comes with 6 devices featuring the Murata Type 2AB module which has our QM33120W inside.

The cable was connected to port j-9 (meant for debugging and flashing), this suggestions makes sense. I’ll try out your suggestion soon and get back to you .
me and my team-mate are still new to this,so can you please point us to some resources/guide (already gone through the entire quick-start guide,developer guide and the read.me in the sdk folder) for performing RTLS with four DWM3001CDK(3 anchors and 1 tag).
Just wish to build a proof of concept,how should we go about it ???

Hi @Ansh_semwal , regarding building an RTLS using TDoA system, as we do not have any examples in our software of doing this, we do not have any getting started guide on this. Many of our partners (including LEAPS which I mentioned above) are experts in this. You may look at some of our documentation regarding RTLS in our app notes here: Application Notes - Qorvo. Perhaps APS003 and APS007.

You can also look into building a simpler (less complex but less scalable) RTLS system using TWR.

I would also refer you to some of the upcoming work being done in FiRa for RTLS and indoor navigation.

Hi @akash !
Our previous conversation helped us a lot, and as of now we can connect multiple DWM3001CDK’s across different laptops and see the distance via CLI. Therefore we are able to find the location/coordinates of the Tag with 4 anchors.
Here’s what we want to try next :

  1. This system uses TWR. We know TDoA is not supported with the given SDK. We are considering committing the time and resources to develop RTLS using TDoA. Wanted to know how should we start and is there a repository or codebase we can refer to?
  2. How are the binaries in the SDK actually created? The ones we flash via JLink-Lite while setting up the dev-board

Hi @Ansh_semwal,

  1. There is no reference code for a TDoA system on DW3000 as I mentioned in my previous comment. As our partner, LEAPS has developed this kind of system if you are interested to reach out to them. They also have a full evaluation kit where you can evaluate TDoA right out of the box: Model UDK1 - All-in-One Ultra Wideband Demo Kit – onanoff
  2. The SDK contains the source code which is used to build the documentation. You can refer to the Developer’s Manual to get more information on how to build the firmware.

Thanks a lot for your prompt response!
We’ll contact LEAPS and look into building our own TDoA application from scratch. I will keep you updated on what we do next
