OTA-CPP is a C++ project that provides a framework for implementing Over-the-Air (OTA) updates in embedded systems and IoT devices. It focuses on reliability, lightweight design, and cross-platform support for resource-constrained environments.
- Firmware Updates – Secure download and installation of firmware images.
- Delta Updates – Support for partial updates to reduce bandwidth usage.
- Integrity Checks – Built-in checksum and cryptographic validation of downloaded files.
- Rollback Mechanism – Safe fallback in case of failed updates.
- Transport Agnostic – Works with HTTP, HTTPS, or custom communication protocols.
- Cross-Platform – Designed for microcontrollers, Linux-based systems, and edge devices.
- Configurable Storage – Support for flash memory, SD cards, or other storage mediums.
- IoT devices requiring remote firmware upgrades
- Embedded systems in automotive, industrial, or consumer electronics
- Edge devices with limited connectivity needing secure update mechanisms
- Add support for encrypted firmware bundles
- Integrate with cloud-based OTA management services
- Provide unit tests and CI/CD pipelines for automated validation
