Multi-Connections at same time possible on newest version of Channel Sounding for ranging Initiator/Reflector?

NickDeLeenheer

Hi,

I was wondering if the newest sample available in NCS3.0.1 is already capable of holding multi connections. Otherwise, for this little time that is present i will do my own implementation to connect with the boards sequentially...

Also, would it be hard to implement multiple antennas to my nRF54L15 boards? I think that multiple antenna paths would increase accuracy, since the accuracy of the distance estimation is very dependent on the specific shortest path that it found. nRF54L15 only has 1 Antenna path (i Think). And if it has more, is it easy to configure multiple antenna paths?

A last question on how to improve accuracy: Is the ifft better for inside? It uses the same phase samples as the Phase Slope method, but i was wondering how it works and where i can find the implementation, because it seems better for now. I also was wondering why it is now taking longer to get my distances with the same configuration compared to the previous version of this sample?

Kind regards,

Nick De Leenheer

    Hi,

    Yesterday i did measurements, and i must say... it works, but it is pretty slow. And with a lot of beacons, it takes longer because of large memory being used i think. i am making an initiator who reconnects with multiple devices and i succeeded in this matter, altough it is not yet very good...

    I am still looking forward on improving my code.

    Kind regards,

    Hi Nick,

    I am curious about how you actually implemented the system to reconnect with multiple devices. Did you put them in a queue and make them retrieve data one by one and then dequeue after? If so did you implement a queue structure in the reflector code? I am also concerned about the memory, as I have observed, conducting multiple channel sounding procedures at once slows each one down significantly and sometimes causes one of them to stop updating completely, but I am using a free for all system where multiple initiators work all at once. Thanks for your response.

    Sincerely,

    Triscuit
