https://devzone.nordicsemi.com/f/nordic-q-a/94664/problem-about-the-direction-finding-white-paper-nwp-036Hi, as stated at page 15 in the Direction Finding white paper(nWP-036), it says &#39;When the last switch pattern is reached and IQ sampling continues, the switch pattern loops back to the one used in the first SWITCH slot&#39;. Does this mean, combined withen-USTelligent Community 13Fri, 09 Dec 2022 10:04:35 GMThttps://devzone.nordicsemi.com/thread/399874?ContentTypeID=1Fri, 09 Dec 2022 10:04:35 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3a5d9abe-2c04-49f2-8c61-20505e4dd682Simonr<p>Hi</p> <p>Yes, the switch pattern here goes between antennas 3, 4 and 5 in example figure 12. In figure 10, antenna 1 is indeed only used for the reference period, but this is not necessary. You can set it up to do switching/sampling on all available antennas as well, like what is done in our <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/samples/bluetooth/direction_finding_connectionless_rx/README.html">Direction Finding sample projects</a> in the nRF Connect SDK.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
