OTA Firmware Updates
Secure, reliable over-the-air firmware update pipelines for deployed devices
Ship improvements to thousands of devices in the field — safely and atomically.
What This Service
Actually Covers
Deployed devices without OTA are frozen in time. We design and implement secure, atomic OTA update pipelines — including dual-bank flash partitioning, cryptographic signature verification, rollback-on-failure safety nets, and delta update support. Whether you are updating 10 devices or 100,000, the pipeline scales and never bricks a device.

How We Approach
This Service
A clear, structured methodology tailored specifically to this engagement.
Partition & Bootloader Design
Design the flash partition map, select or implement a bootloader (MCUboot, custom), and define the update state machine.
Signing & Security Pipeline
Set up firmware signing infrastructure, key management, and on-device signature verification.
Update Client & Backend Integration
Implement the on-device OTA client and integrate with your cloud backend or OTA management platform.
Failure Testing & Rollout Validation
Simulate power cuts, network drops, and corrupt images during update to verify atomic rollback works correctly.
Ideal For
Any IoT product deployed in the field that needs to receive bug fixes, feature updates, or security patches post-manufacture.
What You Receive
OTA-capable bootloader, firmware update client, signing toolchain, backend integration, and failure-mode test report.
