Nordic Distance Measurement library

The Distance Measurement library measures the distance between nRF52 Series devices. It does the following:

  • It provides an easy-to-use interface for measuring distances.

  • It computes the distance using all the information available to the device.

  • It computes the distance based on the measured differential RF physical channel frequency response (MCPD mode) or the real time flight of packets (RTT mode).

  • It performs all the mathematics necessary to compute the distance inside the library.

The library is available as hard-float builds for the nRF52 Series, and it is included as a pre-built static library.

The library has the following dependencies:

  • The DSP math library from CMSIS/DSP.

  • The functions from the C Library math.h.
