https://devzone.nordicsemi.com/f/nordic-q-a/56567/--technical-assistance-request-rfq-qb390ffHello, I contact to you because a customer us interested on the part number #nRF52811, and they made the following questions, forwarded from our customer service representative; “Customer is looking for a device for a real-time monitoring of testen-USTelligent Community 13Wed, 15 Jan 2020 12:27:03 GMThttps://devzone.nordicsemi.com/thread/229210?ContentTypeID=1Wed, 15 Jan 2020 12:27:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2f7c39ba-c9ab-4eb6-a2e0-5c8fe4248d44Simonr<p>Hi Miguel</p> <p>The <a href="https://infocenter.nordicsemi.com/topic/struct_nrf52/struct/nrf52811.html">nRF52811 </a>or the <a href="https://infocenter.nordicsemi.com/topic/struct_nrf52/struct/nrf52833.html">nRF52833 </a>would be the best fit for this use case.&nbsp; Both devices support BLE direction finding (AoA and AoD). The main difference between the two devices is that the nRF52833 has bigger RAM and Flash Memory, and can, therefore, support larger applications. So depending on the size of the intended application they should choose one of these devices. The nRF52811 should be sufficient for a basic real-time monitoring application.</p> <p>As of yet, we do not have any examples for hardware (where an antenna array will be necessary) or software projects for direction finding I&#39;m afraid, so the support we can provide is limited.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
