I am student and my question is in nRF52833 how the feature of direction finding can be used ? From my understanding it has one antenna which provide CTE or IQ samples that can be used for AoA and AoD calculation. How is it possible with one antenna. if i would like to implement this between three BLE devices how this can be done ? Is it really that i need an antenna array wither on RX or TX side ?
second confusion is from the software part nRF SDK, from where i will get the CTE packet and how can i use it ? is there any example provided in SDK for direction finding?
Thanks in advance
