SEGGER Studio firmware for Nordic multi-sensor IoT devices. QUESTIONS Can you share PCB dimensions/space available and current antenna setup? BLE RSSI OK or prefer UWB/AoA? Number of beacons and power constraints? ESTIMATED TIME: 6-10 days.

@jimsufficiency

I can help with this. I can work with nRF52/nRF52840, BLE beacons, and practical ranging techniques (RSSI-based and hybrid approaches), including firmware in C using SEGGER Embedded Studio. I can: • Propose a realistic distance-measurement approach (±20 cm target) suited to your PCB constraints • Update the schematic / PCB for any required RF or sensor additions • Implement and integrate the ranging firmware into your existing codebase • Deliver clean code, build instructions, and concise documentation Happy to review your current PCB and discuss the best technology trade-off (accuracy, power, cost).

@olegwork673

Hello, I already have a working UWB + nRF52840 distance-measurement tag PCB. I understand you have an existing nRF52840-based PCB and need to add a reliable distance-measurement capability to a fixed reference point (beacon) with approximately ±10 cm accuracy, including both hardware updates and firmware integration. Technical Approach -Evaluate feasible ranging technologies for ±10 cm accuracy (BLE RSSI limitations vs AoA/AoD vs UWB coprocessor). -Propose the most realistic solution based on PCB space, antenna layout, power budget, and cost constraints. -Integrate required hardware additions into the existing schematic (RF/UWB module, matching, power, interfaces). -Implement distance-measurement firmware in C using SEGGER Embedded Studio. -Integrate ranging logic cleanly into your existing firmware architecture. Confirmations -nRF52840-based design with existing BLE stack -SEGGER Embedded Studio workflow -Hardware + firmware scope (no PCB layout unless explicitly required) -Distance resolution target: ~±10 cm Key Considerations -BLE RSSI alone is unlikely to meet ±10 cm reliably; UWB or AoA-based solutions will be recommended if accuracy is critical. -Design decisions will explicitly balance accuracy, power consumption, BOM cost, and certification impact. Timeline and final architecture will be defined after reviewing your PCB constraints and preferred technology direction. Regards, Oleg.

Hi, Hope you're doing well. I have more than 24 years of experience in embedded product design and development. I have expertise in IoT products development using BLE, Wi-Fi, Cellular, GNSS, LoRa etc. I have been working on Nordic Platform since 9 years and worked on almost all BLE SOCs, WiFi SOCs and LTE modules like nRF51822, nRF51844, nRF52832, NRF52840, nRF52810,nRF52833, nRF5340, nRF7002, NRF9160, nRF9151, nRF54L15 etc. Recently, I have evaluated nRF54L15 which supports channel sounding feature (for distance measurement) which is aligned to your requirements. It's very low power BLE SOC and have good flash and RAM. Channel sounding is supported by this BLE SOC but not by nRF52840 BLE SOC. If you want to go ahead with RF52840 only then the only solution is distance measurement based on RSSI value. I have hands on experience in firmware development for various BLE profiles based application using above SOCs and modules. I have nRF52832-DK, nRF52840-DK, nRF5340-Dk, nRf9160-DK, nRF52833-DK, nRF7002-DK etc for development and testing. I have developed applications using Nordic BLE SDK (serger studio) and developing using Nordic Connect SDK (Zephyr RTOS using VS code). I have expertise in sensors integrations, OTA, power optimisation etc. I am sure I can help you in your requirement. Let's discuss. Thanks and best regards, Jitendra

**Best Desarrollo Hardware + Firmware nRF52840 (BLE/Beacon) Expert ⭐⭐⭐⭐⭐** Hi, Gracias por compartir el alcance con tanta claridad. He trabajado con nRF52 (incluido nRF52840), BLE beacons y técnicas de ranging, además de modificaciones de PCB e integración de firmware en proyectos existentes. Tu proyecto se ve totalmente viable. El objetivo es simple: añadir medición de distancia respecto a un punto fijo con ~±20 cm e integrarlo en tu hardware y firmware actual. ✅ Cómo te ayudaré a tener éxito 1. Revisar tu PCB actual y proponer la tecnología más realista para ±20 cm (UWB, AoA/AoD, RSSI calibrado u otra), explicando pros/contras y requisitos de hardware. 2. Diseñar e integrar los cambios de hardware necesarios (módulo/sensores/RF, alimentación, señales, test points) manteniendo compatibilidad con tu diseño actual. 3. Desarrollar firmware en C para la medición de distancia y su lógica (filtros, calibración, manejo de errores, límites). ✅ He realizado proyectos de BLE, beacons y sistemas embebidos de bajo consumo donde la estabilidad RF, la calibración y la integración limpia con firmware existente son clave. Puedo compartir ejemplos relevantes cuando me escribas. ✅ Antes de empezar, una pregunta rápida: ¿Tienes espacio disponible en la PCB para añadir componentes (por ejemplo, UWB) y ya cuentas con antena/RF frontend en el diseño actual? Si me compartes el proyecto/archivos actuales, puedo revisar y proponerte el mejor enfoque. Best, Prat PCB Must Innovations

Hey, there! Accurate distance measurement on nRF52840 can be challenging due to RSSI instability, antenna design limits, and firmware integration complexity, and I can help by selecting the right ranging approach and implementing it cleanly end to end. I have strong experience with Nordic nRF52 (including nRF52840), embedded C, BLE beacons, and distance estimation techniques, and I’ve worked on projects that required both PCB-level changes and low-level firmware development. I can propose a realistic hardware solution (RSSI, AoA, or alternative depending on accuracy, cost, and power constraints), integrate it into your existing PCB, and develop reliable firmware using SEGGER Embedded Studio. I’m comfortable working with existing codebases, documenting the design clearly, and delivering production-ready results without hand-holding. If you want someone who can own both the hardware and firmware side and help you reach practical ±20 cm accuracy, I’d be happy to discuss the best approach for your setup.
