About this Gig
Welcome to my gig
A medical wearable is only as reliable as the firmware controlling its sensor acquisition, wireless communication, and power consumption. I develop specialized Bluetooth Low Energy (BLE) firmware for Nordic nRF52840-based medical and health-monitoring devices, focusing on stable connectivity, efficient data handling, and low power embedded performance.
WHAT I WILL PROVIDE
- Custom nRF52840 BLE firmware development
- Sensor integration and real time data acquisition
- Custom GATT services and characteristics
- Secure pairing and wireless data transmission
- Low-power optimization and battery management
- Firmware debugging, testing and documentation
WHY CHOOSE ME
- Nordic BLE development expertise
- Reliable embedded architecture
- Clean, scalable and maintainable firmware
- Focus on power and communication efficiency

FAQ
Can you develop custom BLE firmware for the nRF52840?
Yes. I develop custom BLE firmware using Nordic nRF Connect SDK, Zephyr RTOS and Embedded C, including device configuration, GATT services and wireless communication.
Can you integrate ECG, PPG and SpO₂ sensors?
Yes. I can integrate compatible biosensors for ECG, PPG, SpO₂ and heart rate monitoring, depending on the sensor specifications and hardware architecture.
Do you support custom BLE GATT services?
Yes. I can implement custom GATT services, characteristics, notifications, indications and data transmission protocols based on your application requirements.
Can you optimize firmware for low-power wearable devices?
Yes. I implement power optimization techniques, including sleep modes, advertising intervals, connection parameters and efficient peripheral management.
Can you debug existing nRF52840 firmware?
Yes. I can investigate BLE connectivity issues, sensor communication failures, firmware crashes, timing problems and power consumption inefficiencies.
