I have experience developing embedded firmware for IoT and battery-powered devices, including BLE communication, sensor integration, and low-power optimization. Your requirement for motion/touch sensor monitoring, timestamped data streaming, BLE with Wi-Fi fallback, and reliable reconnect logic is something we at HardFault can handle smoothly. We can deliver clean, well-documented firmware along with testing routines, pin mapping, and concise documentation for easy integration and long-term stability. Also, why settle for an individual freelancer when you can have a dedicated team at HardFault working on your product? You get firmware, hardware, and testing expertise together to ensure stable 24/7 performance and faster issue resolution. One quick question — do you already have the preferred dashboard/API structure for the streamed activity data?

I’ve been building production firmware for over a decade, and your project is exactly the kind of work I do best. ESP32, sensor integration, cloud connectivity, and custom PCB design are all in my wheelhouse. I’ve shipped complete products like a smart vending machine with blockchain payments and a solar-powered water dispenser with zero internet dependency, so I know how to make hardware and firmware work together reliably. I can handle the full stack from firmware to PCB layout and get you a working prototype shipped.

I’ve been working with ESP32 and STM32 for about six years now, and your smart home display project caught my eye right away. I love how you’re thinking about both the hardware interaction and the cloud side of things. I recently designed a custom PCB for a similar multi-sensor setup, so I’m confident I can handle the firmware and bring-up work here. I can take this from the schematic review all the way through to a working prototype that ships to you, handling the PCB layout and 3D enclosure design myself.

Hi, I can develop the complete embedded firmware stack for your IoT activity-tracking device, including sensor acquisition, BLE/Wi-Fi streaming, low-power optimization, reconnect handling, diagnostics, and long-duration stability testing. My background is in embedded systems, IoT, and battery-powered devices, using platforms such as ESP32, STM32, RP2040, Raspberry Pi, and FPGAs. I’ve worked on real-time sensor acquisition, wireless communication, MQTT/BLE systems, and low-level driver development, so this project fits well with my experience. I focus on firmware that is stable in real hardware conditions, not just demo-level code. The 24-hour continuous streaming and automatic recovery requirements are completely reasonable and will be part of validation testing. To start, I’ll need: • MCU/module part number • Sensor model numbers • Current schematic or board photos • Preferred SDK/toolchain • Desired sampling/data rate targets I can begin immediately after reviewing the hardware details. Thanks.

Hi, I have experience with embedded firmware development for IoT devices including BLE communication, low-power optimization, and sensor integration. What I'll deliver: - Firmware in C/C++ for motion and touch sensor reading with efficient data structuring - BLE streaming with Wi-Fi fallback and automatic reconnection after power cycle - Low-power sleep/wake cycles optimized for 24hr+ battery life - Timestamped data samples with integration test routine via serial console and BLE - README with build steps, pin mapping and firmware update instructions - Short report covering power profile, data rate and tuning options Timeline: 5-7 days Bid: 9,000 Quick question — which microcontroller/module are you using so I can confirm SDK compatibility before we begin?

Hello, Hope You Doing Great I am an Embedded Systems and IoT Developer with experience building sensor-based embedded solutions, including an Inventory Management Robot, Smart Home Automation System, Posture Monitoring System, and Heart Rate Monitoring Device. For your project, I can develop efficient C/C++ firmware to acquire motion and touch sensor data, timestamp and structure it, stream it via BLE (with Wi-Fi fallback), and implement low-power optimization for extended battery life. I will provide clean, well-documented code, build instructions, BLE/serial testing routines, pin-mapping documentation, and a brief report covering power consumption and data rates. My experience with sensor integration, wireless communication, and battery-powered IoT devices enables me to deliver reliable firmware that supports continuous operation and automatic reconnection after power cycles. I would be happy to discuss the hardware platform and project details. Best regards, Muhammad Subhan Asad

@embeddedshiv

Hello, This project is a strong fit for my embedded/IoT experience, especially battery-powered sensor devices and BLE data streaming. I can develop clean, well-documented C/C++ firmware under your vendor SDK to read motion and touch sensor data, timestamp samples, format payloads efficiently, and stream them over BLE with Wi-Fi fallback if required. I will also implement low-power techniques such as sleep modes, optimized sampling, wake-on-event logic, and reconnect handling after power cycles. I can deliver: • Firmware source code and build scripts • Sensor/pin mapping and schematic annotation • Serial + BLE live data test routine • README with build, flashing, and firmware update steps • Short report covering power profile, data rate, tuning options, and test results The firmware will be structured for reliability, maintainability, and 24-hour continuous operation on your dev board. To start correctly, I would need these details: • Exact microcontroller/module and vendor SDK • Motion/touch sensor part numbers • Required BLE payload format or dashboard protocol • Sampling rate/data rate expectations • Battery type/capacity and target runtime • Whether Wi-Fi fallback is mandatory or optional I have experience with embedded systems, IoT firmware, sensor integration, BLE communication, and low-power device design, so I can help bring the board to a stable working prototype.

Hello, Your project aligns very closely with the kind of embedded and IoT development I work on professionally. I have hands-on experience with embedded C firmware development, BLE communication, sensor interfacing, low-power optimization, and real-time data acquisition for microcontroller-based systems. From your requirements, I understand the firmware needs to: • Read motion and touch sensor data reliably • Structure and timestamp activity samples efficiently • Stream live data over BLE with Wi-Fi fallback support • Handle reconnection automatically after reboot/power cycle • Maintain low power consumption for battery operation • Well-documented source code and build instructions • BLE test/debug routines with serial monitoring • Pin mapping and sensor integration documentation • Power optimization recommendations and tuning options • Stable reconnect and watchdog handling for reliability My background is mainly in embedded systems and firmware development, including MCU bring-up, communication protocols (BLE/UART/I2C/SPI), power management, and production-oriented debugging. I focus on writing maintainable firmware rather than quick prototype code, so the project remains scalable for future updates. I would be glad to discuss: • MCU/module being used • Sensor models/interfaces • Expected BLE packet structure/data rate • Battery/runtime expectations • OTA/firmware update requirements if needed Looking forward to working with you on this IoT device.
