https://devzone.nordicsemi.com/f/nordic-q-a/99533/ble-aoa-direction-findingHi, 1. In context to AOA, I have a transmitter nordic tag and receiver -Corehw- 4X4 antenna array. I am getting the iq samples from the receiver after switching the antennas in the array. I need to understand if any signal processing of iq samples areen-USTelligent Community 13Tue, 09 May 2023 14:29:35 GMThttps://devzone.nordicsemi.com/thread/424608?ContentTypeID=1Tue, 09 May 2023 14:29:35 GMT137ad170-7792-4731-bb38-c0d22fbe4515:206d9ec7-1e14-4dd1-97e2-b4bc6d510155Simonr<p>Hi</p> <p>1. The IQ data you receive is raw IQ data that must be&nbsp;c<span>onverted into vector form to be reviewed properly. We don&#39;t have have any specific sample code showing this, but you can check out&nbsp;</span><a title="https://www.pe0sat.vgnet.nl/sdr/iq-data-explained/" href="https://www.pe0sat.vgnet.nl/sdr/iq-data-explained/" rel="noopener noreferrer" target="_blank">this page</a><span>&nbsp;for information on the various formulas used to translate IQ data between polar and rectangular form. </span></p> <p><span>2. Nordic will not provide a Direction Finding algorithm. This will have to be done on your end or by a third party. <a href="https://webinars.nordicsemi.com/integrating-bluetooth-direction-3">UBlox for example</a> provides a full solution with both HW and AoA algorithm for customers using their nRF modules.</span></p> <p><span>Best regards,</span></p> <p><span>Simon</span></p><div style="clear:both;"></div>
