El patrón que describes —reed switch NO, wake-up por GPIO en el nRF52810 y advertising hacia el PCA10059 como hub— evita justo el emparejamiento manual que mencionas como preferencia. - Firmware: nRF5 SDK sobre SEGGER Embedded Studio, más ligero que nRF Connect SDK/Zephyr para este alcance puntual; GPIOTE en modo SENSE para despertar solo con la activación real y volver a System OFF tras enviar el paquete, cuidando la CR1225. - Enlace nRF52810–PCA10059: advertising BLE no conectable con manufacturer-specific data con el ID del vertedor; el PCA10059 escanea y actúa de bridge USB CDC/serial hacia la PC, sin stack BLE completo en el host. - Punto abierto: ¿el ID del vertedor va grabado de fábrica o debe ser configurable en campo (DIP switch, comando UART)? Conviene cerrarlo antes de programar, define firmware y script de registro. Trabajo regularmente con integraciones embedded/BLE y puedo compartir portafolio relevante desde mi perfil de Freelancer. Entrego el primer hito funcional (10 activaciones registradas con ID y timestamp) en 2 semanas. Toma el importe de esta propuesta como referencia inicial y orientativa para el alcance descrito, no como precio definitivo; lo confirmamos al cerrar el punto del ID y el número de vertedores de la prueba. Trabajo como freelancer individual, sin agencia. Propongo una llamada breve aquí en Freelancer para repasar estos puntos antes de arrancar.

Hola, soy Leo Sarmiento, ingeniero embedded especializado en Nordic nRF52 y BLE con más de 10 años de experiencia en firmware de bajo consumo y sistemas IoT. El desafío real no es encender el LED, sino lograr que el nRF52810 despierte desde deep sleep, lea el reed switch y transmita el evento vía advertising no conectable en milisegundos, para luego volver a dormir sin que la batería tipo moneda se agote en días; además, la recepción por el dongle nRF52840 debe manejar múltiples dispositivos sin colisiones, por lo que recomiendo usar advertising packets con intervalos aleatorizados y un ID único en el payload.

@electronicsdone

Hi, The biggest challenge in this project is not simply transmitting a BLE event—it is achieving ultra-low power operation while ensuring every reed switch activation is reliably detected, transmitted, and received without missed events in a busy indoor Bluetooth environment. I have 30 years of experience in Nordic nRF52 development, Bluetooth Low Energy (BLE), low-power embedded systems, GPIO wake-up, wireless sensor networks, and IoT device integration. For this project, I would focus on: 1. Developing a low-power BLE solution on the nRF52810 that wakes on reed switch activation, broadcasts a unique device ID, and quickly returns to sleep. 2. Configuring the nRF52840 PCA10059 dongle as a reliable BLE receiver that captures events from one or multiple devices and forwards them to the PC. 3. Delivering complete documentation, source code, wiring diagrams, and a simple PC application for event logging and future scalability. ✅ A Few Quick Questions: 1. Do you already have the nRF52810 and PCA10059 hardware available for testing? 2. Would you prefer BLE Advertising or a Connected BLE solution for communication? If you message me, I can outline the most reliable low-power BLE architecture for accurate event detection and seamless communication between the nRF52810 and the nRF52840 receiver. Best regards, Prat PCB Must Innovations

I understand you're building a low-power IoT prototype for a smart beverage dispenser, requiring precise detection of bottle pours via a reed switch and BLE transmission. My experience with Nordic nRF52 series, particularly the nRF52840, and implementing custom BLE services for event-driven data transfer directly aligns with your project's core requirements. I've successfully delivered similar solutions for real-time sensor event reporting to a central hub. My technical approach will involve leveraging the nRF Connect SDK. I will configure the nRF52840 to use its GPIO for reed switch input, enabling interrupt-driven detection for minimal power consumption. A custom BLE advertising packet or GATT notification will be implemented to send a unique pour event ID and device identifier upon reed switch activation. Power optimization techniques, including sleep modes and judicious peripheral usage, will be paramount. To ensure optimal performance, could you clarify the maximum expected pour frequency and the desired latency for BLE event transmission? I'm confident I can deliver a robust and efficient solution. I'm available to discuss the project further and answer any technical questions you may have.

Hello Dear, I’m an experienced Full-Stack Developer with 10+ years of experience and a B.Sc. in Computer Science and Engineering from BUET. I have extensive experience developing embedded systems, IoT solutions, BLE communication, and low-power firmware with a strong focus on reliability and maintainability. I understand you need a low-power Nordic nRF52810 prototype that wakes from GPIO, broadcasts BLE advertising packets with a unique device ID, and communicates with an nRF52840 PCA10059 hub for PC event logging. I recommend **nRF Connect SDK (Zephyr)** for long-term support, scalability, and excellent BLE capabilities. BLE non-connectable advertising is the most efficient approach for your multi-device, battery-powered architecture. My experience in Embedded C, Nordic nRF52, BLE, Zephyr, GPIO wake-up, Python, UART/USB, and low-power firmware development. Feel free to share your current hardware files. I’m ready to begin immediately. Looking forward to hearing from you. Best regards, Md Ruhul Ajom

Hola, puedo ayudarte a llevar este prototipo BLE con Nordic nRF52 a una prueba funcional, documentada y replicable. Tengo experiencia práctica en firmware embedded en C, bajo consumo, wake-up por GPIO, BLE advertising, BLE UART/central-peripheral y trabajo con chips Nordic como nRF52810, nRF52832, nRF52840 y dongles PCA10059. Para este caso recomiendo usar BLE advertising no conectable desde el nRF52810, incluyendo el ID único del vertedor y un contador/timestamp interno del evento. Así evitamos emparejamiento manual, reducimos consumo y facilitamos escalar de 1 a 5 vertedores. El PCA10059 puede actuar como scanner/receptor BLE y enviar los eventos a la PC por USB/serial, donde prepararé un script Python para registrar ID + fecha/hora. Puedo entregar firmware compilable, archivos .hex, README, diagrama de conexión, código comentado y prueba documentada. Para el primer hito funcional estimo 5–7 días, validando 10 activaciones del reed switch con 10 eventos recibidos correctamente. Trabajo directamente como freelancer/persona, no como agencia.

Hola, puedo desarrollar el prototipo Nordic BLE para el vertedor inteligente, usando nRF52810 como transmisor de bajo consumo y nRF52840 PCA10059 como receptor/hub conectado a PC. La mejor solución es usar BLE advertising no conectable para enviar eventos rápidos sin emparejamiento manual. Primero revisaré el circuito actual, reed switch, batería, GPIO wake-up y consumo. Luego desarrollaré firmware en C para que el nRF52810 despierte al activar el reed switch, envíe el ID único del vertedor por BLE y vuelva a bajo consumo. Tengo experiencia con Nordic nRF52, BLE advertising, wake-up por GPIO, bajo consumo, firmware embedded en C, nRF Connect Programmer, nRF5 SDK / nRF Connect SDK, PCA10059, comunicación USB/serial y scripts Python para registro de eventos. Entregables incluirán: * Firmware nRF52810 * Configuración/firmware PCA10059 * Archivos `.hex` * Código fuente comentado * BLE event packet con ID único * Script PC para registrar ID + timestamp * Diagrama de conexión * README paso a paso * Prueba funcional documentada * Recomendaciones de batería * Guía para escalar a 1–5 vertedores Para el primer hito, entregaré una prueba donde 10 activaciones del reed switch generen 10 eventos correctos en la computadora. Trabajo directamente como freelancer, no agencia. Best regards Ankit
