I will develop nrf52 nrf52840, ble firmware, iot and embedded system
About this Gig
Hello!!
Need reliable firmware for an nRF52 or nRF52840-based device? I can help develop custom BLE firmware, embedded systems, IoT functionality, sensor integration, and device communication tailored to your project requirements.
I focus on creating clean, maintainable firmware designed around your hardware, communication requirements, and intended application
What I can develop
- nRF52 / nRF52840 firmware
- Custom BLE services and characteristics
- BLE advertising and connection configuration
- BLE GATT/GAP functionality
- Sensor and peripheral integration
- GPIO, PWM, ADC, UART, SPI and I2C
- Battery-powered and low-power applications
- IoT device firmware
- Wireless device communication
- BLE data transmission and monitoring
- Button, LED and display control
Whether you need a small BLE feature, a sensor-based nRF52840 application, or a larger embedded IoT system, we can define the exact scope before development begins.
Send me your requirements, hardware details, datasheet/schematic, existing code (if any), and expected functionality so I can determine the appropriate package for your project.

FAQ
Can you develop firmware for nRF52840?
Yes. I can develop and modify firmware for nRF52-series devices, including nRF52840-based projects, depending on the hardware and development environment.
Can you create custom BLE services and characteristics?
Yes. I can implement custom BLE GATT services and characteristics, including read, write, notify and related communication functionality according to your specification.
Can you work with sensors and external modules?
Yes. I can integrate supported sensors and peripherals using interfaces such as I2C, SPI, UART, GPIO, ADC and PWM.
Can you fix existing nRF52 firmware?
Yes. You can provide your existing source code and describe the problem. I can investigate bugs, communication problems, unexpected behavior and other firmware issues within the agreed scope.
Do you work with existing hardware?
Yes. Hardware documentation such as a schematic, pinout, datasheet or development-board information is very useful for accurate firmware development.
Can you develop an entire IoT device?
I can develop the embedded firmware portion of an IoT device. If your project also requires a mobile application, web dashboard, cloud backend or other software, those components should be discussed separately.
What do you need from me before starting?
Please provide your MCU/board information, schematic or pinout if available, firmware requirements, BLE specifications, sensor/peripheral details, existing source code if applicable, and a description of the expected device behavior.
Can you test the firmware?
Yes, testing can be included within the agreed scope. If physical hardware is required and cannot be provided, testing may be limited to the available development environment and information.
Can you handle a custom embedded project?
Yes. For larger or unusual projects, contact me first with the requirements so the scope, development time and appropriate price can be determined accurately.
