Bluetooth 5.1 Direction Finding

The nRF52833 includes a radio capable of Bluetooth® 5.1

Direction Finding. Direction Finding enables positioning

solutions to not only rely on received signal strength indicator

(RSSI), but also the actual direction of a signal. This improves

accuracy and opens new possibilities for applications in this

segment. There are two types of methods for determining

direction, angle of arrival (AoA), where the direction of the

received signal is calculated, and angle of departure (AoD),

where the direction of the transmitted signal is calculated. In

addition to act as a simple transmitter in either scheme, the

generous available memory and processing power on the

nRF52833 also allows for calculating the angles when being

a receiver in either AoA or AoD mode. Illustrated below is an

example of a real time location system (RTLS) where the

principle of AoA is used to deremine the location of a tag.

Get started today

The nRF52833 is supported by the nRF5 SDK, nRF5 SDK for

Mesh and nRF5 SDK for Thread & Zigbee. The SDKs provide

all necessary examples, libraries and drivers to get started

with Bluetooth Low Energy, Bluetooth mesh, Thread or Zigbee

development. The nRF52833 has Bluetooth 5.1 qualified

protocol stack support using either the S113 or S140 SoftDevices

from Nordic Semiconductor. S140 is a feature complete

Bluetooth 5 protocol stack and includes support for high

throughput with 2 Mbps transfer, Bluetooth Long Range, and

improved coexistence with Channel Selection Algorithm #2.

The available nRF52833 DK is an affordable single-board

development kit for

Bluetooth® 5.1, Bluetooth mesh, Thread,

Zigbee, 802.15.4 and 2.4 GHz proprietary applications using

the nRF52833 multi-protocol SoC. The kit is compatible with the

Arduino Uno Rev3 standard, has access to all I/Os (42) and

interfaces via connectors, and there is an integrated PCB trace

antenna and an RF connector for direct RF test measurements.
