NRF52833 Bluetooth Direction Finding

A radio capable of Bluetooth® Direction Finding is included in the nRF52833. With Direction Finding, positioning solutions can rely on not just the received signal strength indicator (RSSI), but also the signal's true direction. This enhances precision and expands the range of applications available in this market. The angle of arrival (AoA), which calculates the direction of the received signal, and angle of departure (AoD), which calculates the direction of the transmitted signal, are the two sorts of methods for detecting direction.
