Renesas / Dialog SmartBond™ Wireless Ranging SDK uses the DA1469x family of BLUETOOTH® LE SoCs with highly accurate and reliable distance measurement capabilities. The WiRa SDK uses radar-like implementation to greatly enhance distance measurement for connected devices. This amounts to +/- 0.5 meters in typical situations. The result is a solution with 10x the accuracy of competing RSSI-based localization options.
