WiRa range support

Hi Guys

 I am working on your new device: 14695 DK board for ranging development on the SDK version@WiRa_10.440.8.6. and I want to output the raw data IQ data from both 2 devices: iniator / responder . then to estimate the distance between these 2 device :

 so as to output these 2 device end raw IQ data and seperate them which datas are from iniator ? responser?  my operation is as following:

1. switch to "host_apps" and edit the PP_data in this diectory file " dte_IQ_data_anaylyzer.py" then print out to IQ.txt file .

2. change the " ble_range_dte.h" setting parameter (#define EXCHANGE_MODE                   (0)) .and compile /flash the DK board.

3. then switch to "CMD" mode to run " python dete_iq_data_analyzer.py" file , the system expert the IQ.txt file .

  my understanding that total IQ numbers are 5120 for total 40 atoms . very atom have 128 IQs (which include 64 iniator IQs and 64 responder IQs)

3.1 inside these 5120 IQs. we assume that first 2560 IQs are from iniator and next 2560 IQs are from responder. right ?

3.2 very sequence atom (from atom1,atom2.....atom40) .the frequency started from 2402M , then every 2M increased for atom2.if my understanding is right . atom1 's fre =2402. atom2=2404, atom3=2406..... atom40=2478M  ?

3.3. example atom1 .( my understanding: 64 iniator IQ/phase data, 64 responder IQ phase data). what IQ/phase data are effective used for distance caulation? 

 

thanks

thanks for your response . we

thanks for your response . we haved followed "thinks" to calculate the "distance" and find our conclusion maynot be right . so pls help clarify that confuse . 

very thanks

Hi Leison,

Hi Leison,

Just update the status to close the ticket, with the info sent to you last friday and what we talked yesterday, you has parsed the data and calculate the distance successfully.
