FOTA Update | Firmware Over the Air
Delivering wireless updates for your IoT Devices






Whether it is an automotive ECU product, field-deployed Industrial Automation devices, or connected devices for the everyday customer, integrating Firmware over the Air (FOTA) / FOTA update feature has become a mission-critical process.
FOTA update is necessary to ensure secure and robust operations of remote devices in Industry 4.0, automotive, and healthcare domains.
Embitel’s IoT engineering teams develop FOTA Update solutions for embedded IoT devices, enabling real-time updates, improving performance, and enhancing security—anywhere, anytime.
Features of Our FOTA Update Solution for Remote Device Management
- Remote device management through OTA software updates
- Scheduling, release and reporting of the firmware build versions through a web server interface solution
- Controlled and customized OTA software release management, through logical device grouping based on project requirements
- Controlled and customized OTA software release management, through logical device grouping based on project requirements
- Ensuring that device downtime is minimized during updates
- Ensuring that every session of FOTA update is complete and atomic; so that the firmware update does not end in an incomplete/broken state

Firmware Over the Air – Design and Development Services
- Flash Memory Selection – NOT, NAND & more, based on your project requirements.
- Integration of Wi-Fi/Bluetooth/GPRS/GSM modules for secure communication between the FOTA server and the target devices.
- Design and development of Firmware and integration with IoT protocols such as MQTT, CoAP; HTTPS & SSL for secure data exchange; FTP/FTPS for file transfer.
- Selection of specific encryption methods to check the sanity of the update package.
- Deciding the level of FOTA update required (At the whole system level, OS and application level, or only at the application level).
- Bootloader development to enable firmware download and reprogramming on the application device.
- Design and development of the FOTA management server interface and other GUIs to build/schedule/deploy/manage the update package.
- Design and development of the interface (GUI) to build/schedule/deploy/manage the update package.
- Tracking as well as reporting the successful instances of firmware updates.
- Integration of Firmware Rollback mechanism to mitigate any failure or bug detected during Over the Air update.
- Development of Automated test frameworks to enable devices to perform self-test & send status reports, at the end of an update.
After design and development of the FOTA feature for your connected devices, the hardware and software components are subjected to the following pre-production test-case scenarios:
- Power Failure
- Communication Failure
- Memory Corruption
- Failure to boot the new firmware image
- Flashing of a corrupted firmware image
- Failure to retrieve the information about the configuration & last status of the firmware
We also perform Image self-tests to check if all the firmware functions are working properly.
