Localization
Bluetooth® Toolbox features and reference examples enable you to implement Bluetooth direction finding functionalities such as angle of arrival (AoA) and angle of departure (AoD) and Channel Sounding (CS) distance estimation functionalities such as round-trip time (RTT) and phased-based ranging (PBR).
Use the localization capabilities of the toolbox to:
Simulate direction finding and CS packet exchange procedures to track the 2-D or 3-D position of a Bluetooth low energy (LE) node and compute the distance between two Bluetooth LE devices.
Implement lateration, angulation, or distance-angle localization methods and calculate the 2-D or 3-D position of a Bluetooth LE node.
Estimate the maximum range between two Bluetooth basic rate/enhanced data rate (BR/EDR) or LE devices.
Compute the 3-D position of a Bluetooth low energy (LE) node by using the received signal strength indicator (RSSI) fingerprinting and convolutional neural network (CNN).
