Direction Finding enables CPU 64 MHz Arm Cortex-M4 positioning solutions to not only rely on received signal Memory 512 KB Flash + 128 KB RAM Cache strength indicator (RSSI), but also the actual direction of a 8 KB cache Performance signal. This improves accuracy and opens new possibilities 217 CoreMark Efficiency 66 CoreMark/mA for applications in this segment. There are two types of methods for determining direction, angle of arrival (AoA), Hardware se- 128-bit AES CCM, ECB, AAR where the direction of the received signal is calculated, curity and angle of departure (AoD), where the direction of the Wireless protocol Bluetooth Low Energy/Bluetooth mesh/ transmitted signal is calculated. In addition to act as a support NFC/Thread/Zigbee/802.15.4/ANT/2.4 GHz simple transmitter in either scheme, the generous available proprietary memory and processing power on the nRF52833 also On-air data rate Bluetooth LE: 2 Mbps/1 Mbps/125 kbps allows for calculating the angles when being a receiver in 802.15.4: 250 kbps either AoA or AoD mode. Illustrated below is an example TX power Programmable from +8 to -20 dBm in 4 dB of a real time location system (RTLS) where the principle of steps AoA is used to deremine the location of a tag.
