https://devzone.nordicsemi.com/f/nordic-q-a/77582/nrf-52833-aoa-direction-finding-interface-with-wifi-moduleWe are developing AoA direction finding with nrf52833 and antenna array. We also want to include Wifi connectivity to our receiver, having nrf52833 + antenna array.

We were thinking about ESP8266, but are open for any IC.[/quote] <p>None of our products currently support WiFi, and we therefore do not have any WiFi device recommendations, since it is outside of our scope of operation.<br />I have no personal experience with the ESP8266, but I have seen multiple other customers mentioning that they are using this as a WiFi module, so I suppose this is a good choice - but I really can not recommend one over any other at this time. As long as it exposes an interface compatible with the nRF52833, you should be fine to use it.<br /><br />Please keep in mind that the noise generated by a nearby WiFi module might degrade your radio performance. I have not done any tests on this for AoA, but I would think this might be the case here as well. If this turns out to be an issue you could perhaps look into time-slotting the two protocols, so that they might perform to their fullest in their own timeslot.<br /><br />Best regards,<br />Karl</p><div style="clear:both;"></div>
