MDEK1001: Raw Range Measurements

Wireless Connectivity Ultra-Wideband
1

Hi,

We set up our system as follows:

  • Initial Anchor:
    • acas 1 0 0 1 0 2 0
    • Additional Anchor:
      • acas 0 0 0 1 0 2 0
    • Tags:
      • acts 0 0 0 0 0 1 0 2 0

Looking to get raw range measurements from all tags to all anchors from both sides. A couple of questions:

  • Tag is outputting range of the tag to all anchors, and to get all the tag ranges to all the anchors we must plug into all the tags. Is there a way to get all the ranges in the system being plugged into a single tag?
  • Anchor is NOT outputting range data at all, how do we enable range data from the anchor side? Once enabled, is it also possible to get all anchor to all tag ranges by being plugged into a single anchor?

Thanks for the help.

Hi @jwong1
let me help you here.

Re TN) The position is calculated in the TAG so only the TAG knows distances to the anchors. Here are ways how to get distances between TN and AN:

  • directly from TN (via UART/SPI)
  • via bluetooth
  • via UWB IoT, but you need to write your own app to do that

Re AN) there is no way how to obtain distances / location on Anchors.

Cheers
