Hi Kenneth, are you suggesting that the nRF54-series will provide user-accessible raw and IQ phase measurements via an API?

You are right, if you want to try this example, please order yourself an nRF54L15 DK. For new designs using the nRF54-series might be a good suggestion overall.

Thank you very much for your help!Unfortunately, nrf5340dk does not support this example.

Hi,

nRF5340 does support extraction of IQ data.

The most notable example of IQ sample extraction is for Bluetooth Direction Finding, where you get a number of IQ samples in an IQ samples report.

Also Bluetooth, the sample Bluetooth: Channel Sounding Initiator with Ranging Requestor provides a basic distance estimation algorithm to demonstrate the IQ data handling. (The algorithm there is not particularly good, though. The point of the sample is to show IQ data handling.)

The Nordic Distance Measurement library is a proprietary, pre-compiled library. The source code is closed, and we do not share it. That is the reason why you cannot use that library as reference, to see how to extract IQ data.
