https://devzone.nordicsemi.com/f/nordic-q-a/73399/nrf52833-aoa-aod-antenna-array-connectionHello! I have the nrf52833 DK and want to connect it to an antenna array for AoA estimation. I plan to have RF output pin to an RF sp6t switch to each of the 6 array elements and control the output of the switch with gpios from the chip.

You will indeed have to use an external RF switch to connect to an antenna array.&nbsp;</p> <p>What we have available regarding Direction finding is rather limited as of yet, but please check out our <a href="https://infocenter.nordicsemi.com/topic/nwp_036/WP/nwp_036/intro.html">Direction Finding whitepaper</a>, which among other things, describes antenna switching configuration.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
