A release path for software and firmware

Capability profile — not a client case study. This outlines delivery engineering BDOT Software can provide. It does not claim a particular team's deployment history or release results.

One product, multiple artifacts

When a product includes a device, its firmware, an API, and an application, each artifact can evolve at a different pace. A deployment pipeline should make those relationships visible rather than assuming the latest version of everything is compatible.

Build a traceable release

Start from a reviewed commit and pin the compiler, base image, and relevant dependencies. Produce versioned artifacts and associate them with a release manifest that records the API compatibility range and firmware update policy. Where signing is required, keep private keys outside ordinary build logs and restrict access to the signing step.

Test failure and recovery

A green build is not enough. Exercise interrupted downloads, low storage, power loss during update, expired credentials, and a device that reconnects after a long outage. Test the backend with both the current and previous supported firmware version. For web services, rehearse database migration and application rollback together.

Keep rollout observable

• Promote the same artifact from staging to production instead of rebuilding it.
• Deploy to a small cohort before widening the rollout.
• Track update attempts, failures, and the version reported by devices.
• Define stop conditions and a rollback path before release day.

The exact pipeline depends on the hardware and deployment model. The durable principle is to treat firmware, application, and service compatibility as a product contract, and make the release process repeatable by someone other than its original author.
