The WiRa announcement this week.

Hi
I have looked for information about how the range is detected.
The best info I came across was 'constant tone frequency' and deriving phase from I-Q values.

Where can I find a detailed explanation of how it works?

Look forward to hearing from you and I thank you in advance.

Hi mtailor,

Hi mtailor,

Thanks for your question on our public BLE forums and for your interest in WiRa SDK! In order to calculate the distance, it is an exchange of constant tone as described in Section 5.1 Dialog Tone Exchange (DTE) Overview , in UM-B-137. Please take a look into the user manual and let us know if you need anything more specific.

Thanks, PM_Dialog
