Implementing Sub-meter RTLS via Angle-of-Arrival (AoA) with Bluetooth 5.1 CTE and Arm Cortex-M33 IQ Sampling Real-Time Locating Systems (RTLS) have evolved from coarse RSSI-based proximity to precision angle-based localization. Bluetooth 5.1 introduced the Constant Tone Extension (CTE), enabling An
