ESP32 Production Firmware

Move beyond a working prototype. Design ESP32 firmware with clear state, reliable connectivity, safe updates, and the observability needed for a real deployed device.

Bring an ESP32 board and leave with a firmware architecture you can extend.

The workshop

Build with guidance, not another slide deck.

Most embedded prototypes fail in the space between “it works on my desk” and the first month in the field. This workshop focuses on that gap: the firmware decisions that make an ESP32 device understandable, recoverable, and maintainable after deployment.

We will work through a production-shaped firmware structure using an ESP32, sensor telemetry, MQTT, and an OTA update path. The goal is not a giant framework — it is a set of patterns you can reuse on the next device you build.

You'll leave with

Practical outcomes you can use immediately.

01Structure firmware as explicit states instead of a growing loop of callbacks.

02Build resilient Wi-Fi and MQTT connection handling with recovery paths.

03Design OTA updates with version checks and a rollback-minded rollout flow.

04Add logs, health signals, and failure visibility before the device ships.

Session plan

Four focused hours.

00:0001

The prototype-to-product gap

Map the failure modes that appear when a connected device leaves the bench.

00:4502

Firmware architecture and state

Separate boot, connectivity, sampling, publishing, and recovery into testable states.

01:4503

Reliable connectivity

Implement reconnect backoff, MQTT session behavior, and useful device health signals.

02:4504

OTA without losing control

Walk through versioning, update checks, failure handling, and safe rollout thinking.

03:3005

Review and next build

Review the architecture, identify gaps, and define the next production checkpoint.
