Real Time Location Using Ultra-Wideband (UWB) (2019)

Ultra-Wideband ranging modules I’ve been looking for a system that can provide fast & accurate position measurement within a defined area; this is generally known as an RTLS (Real Time Lo…

So I’ve created a Python test framework from scratch; at under 1000 lines of code, it can’t compete with the Decawave packages, but hopefully it’ll give an insight as to how the chip works, and enable you to experiment with this interesting technology. Before leaving the subject of device initialisation, it is worth mentioning that I’ve used several Python dictionaries (as lookup tables) to simplify the underlying logic: for example, the transmitter analog setting RF_TXCTRL, which depends on the channel number (1 – 7, excluding 6) This is not the correct approach; if you look at the Decawave source code, they check the status register to look for potential lock-up conditions, and take appropriate action; they don’t wait for multiple failures.
