https://devzone.nordicsemi.com/f/nordic-q-a/106194/ble-direction-finding-16-bit-samplesI&#39;m using the NRF52833-DK with Nordic Antenna Array PCA20054 for BLE Direction Finding purposes. The &quot;direction_finding_connectionless_rx&quot; sample from sdk-nrf returns 8-bit IQ samples in the cte_recv_cb callback.
