Overview
Description
Renesas' Wireless Ranging (WiRa™) Software Development Kit (SDK) enhances the DA1469x family of Bluetooth® Low Energy (LE) System on Chip (SoCs) with highly accurate and reliable distance measurement capabilities. Current market offerings fall short due to the radio signal strength indicator (RSSI), a flawed measure that is sensitive to radio signal blockages. Unlike RSSI, the WiRa™ SDK uses a radar-like implementation to greatly enhance distance measurement for connected devices, amounting to +/- 0.5 meters in typical situations. The result is a solution with 10x the accuracy of competing RSSI-based localization options.
The WiRa™ SDK uses phase-based ranging technology and advanced signal processing to provide reliable distance measurements between connected devices. Built on the DA1469x wireless MCU family, it integrates distance measurement and Bluetooth® LE connectivity into a single-chip solution, including a Bluetooth LE 5.1-compliant stack and software implementation, while ensuring coexistence between Bluetooth communications and the distance measurement process.
This all adds up to a solution that provides end-users with greater reliability, security, and location and tracking accuracy for the IoT devices in peer-to-peer applications.
Features
- Add distance measurement as a feature to your wireless applications
- Achieve 10s of cm accuracy in typical use cases
- Distance reported out within 200ms
- No additional hardware needed compared to standard Bluetooth LE system designs
- A proprietary implementation that co-exists with Bluetooth LE communication
- Comprehensive software suite including data processing algorithms, distance output, UI, and software application example
- Flexibility to further optimize, adapt, or replace data processing algorithms
- Small RAM and MIPS requirements; runs on any DA1469x Bluetooth LE SoC variant
- Suitable for battery-powered devices
- Benefit from the DA1469x on-chip integrated battery charger
- Pre-programmed development kit including two DA14695 Development Kit-USB boards, each fitted with a MikroBUS™ OLED display

- DA14695-00HQDEVKT-RANG-ND not functioning correctly
Hello I ordered 2 weeks ago a Wireless ranging development kit DA14695-00HQDEVKT-RANG-ND from DIGIKEY ( 64453584 / PL1) I started the basic test of connecting the 2 units to USB ports. The precision is far from the promised +- 0.5m. a distance of 30 cm ranges from 0 ...
Jun 15, 2020 - DA14695-00HQDEVKT-RANG Not Working
I just received DA14695-00HQDEVKT-RANG and it is not functioning at all. The LCD backlights are on but there is no text displayed. One of them did respond with a debug menu using a terminal but no longer does. I stupidly programmed the 'factory firmware' on one device and ...
