Using proprietary ranging stack instead of nordic distance toolbox

[Podrick]

Hi all,

I want to evaluate the nordic ranging toolbox and compare it to a proprietary solution. First of all I set up the distance measuring example (developer.nordicsemi.com/.../README.html) with two nrf52840 and got proper ranging results.

Now I want to compare it to a proprietary distance measuring solution. Therefore I need the I,Q samples, the timestamp of the sampling, the transmit frequencies and the down conversion frequencies. Right now I can only get the IQ samples from the struct nrf_dm_iq_tones_t but not the other parameters.

I would also like to understand whether those iq_tones are already frequency offset compensated or not? If not, how do I get the result of a CS mode 0 frequency offset measurement?

Kind regards Podrick

From the team:

• The transmit frequencies can now be read from the 0.7.1 version of the library with the nrf_dm_get_hopping_sequence function
• The timestamp is not available, however, the timing between each tone measurement is constant
• The down conversion frequencies will not be shared
• The internal frequency measurement, and compensation, will not be shared. However, we expect to tune the initiator to within a few kHz of the reflector

Hi, 

I am checking with the team and will update you later.
