Many to Many Support DWM3001CDK

Wireless Connectivity Ultra-Wideband

Hi , I am successfully getting the “one to many” working. Do you know if it’s planned to get the “many to many” support ? Maybe it well be available with the new SDK ? Otherwise, can you point me to how can i develop such feature or attempts done in the past ?

Additional details : I have one initiator , 4 responders - But will have to scale to 15 initiators, 4 responders.

Thanks,

Léo

Please search this forum. The question of how to expand the examples to work with multiple tags/anchors is asked at least once per week.

Hi @AndyA , thanks for this useful answer. Is the response no ? Can you point me to a working example ?

Thanks

You asked “can you point me to how can i develop such feature or attempts done in the past ?”
I pointed you to the search box on this forum.
I could do the search and then post the results but that seems a little pointless since you could easily do exactly the same.

I can’t remember anyone posting final working code, most people only post code that doesn’t work. But the forum has been around for a while so someone may well have posted a link to some working code at some point.

Thanks, i’ve already tried the search box, that’s why i’m posting something. My question is :

  1. Is the many to many still not developped ?
  2. apparently there will be a new software release , should this feature integrated?
  3. if 1 is not developed, Is TDMA possible ? if yes, is someone already try it ?

I mean, it’s a forum to help each other.

And yes please, if you know some other posts , you can link it as it’s normally done in github issues.

  1. The many to many hasn’t been developed as an example because it becomes very application specific.

  2. The SDK is supposed to be a set of building blocks to create a product, not an end product on it’s own. It already has all the building blocks required to do this so there is no need to add it. Will they add an additional example showing how to do this? Maybe. Do they need to? No.

  3. Yes, since the UWB radios can only cope with a single device transmitting at a time every solution to this uses TDMA. All of the forum posts on how to implement this say to use TDMA.
    How you efficiently split the time between units is one of the hardest parts of this and has nothing to do with the drivers for the UWB radio, it’s purely a function of your system design. Which is why a solution to this problem doesn’t really belong in the SDK.
