Why this program matters

Without mastering OTA Updates, 68% of IoT incidents in 2024 stem from outdated firmwares, exposing companies to cyberattacks costing an average of 4,5 millions d'euros per breach according to IBM.
Non-updatable fleets generate 50% additional downtime, delaying product launches by 3 mois and penalizing competitiveness.
Engineers without expert OTA skills are excluded from 75% of embedded DevOps offers.
Every quarter without training widens a critical gap against regulatory standards like ISO 21434, risking massive fines and market losses.

Program

Module 1OTA Updates Fundamentals: Protocols and Embedded Architectures (MQTT, HTTPS, Delta Updates)

Dive into the advanced principles of OTA Updates by analyzing key protocols such as MQTT and HTTPS for constrained environments, configure a test environment with embedded simulators on Raspberry Pi and STM32, develop your first complete OTA payload including metadata and checksums, perform practical exercises on real enterprise cases to identify common pitfalls, produce a custom production-ready architecture diagram.

Module 2OTA Updates Security: Digital Signatures and Advanced Encryption (EdDSA, TLS 1.3, PKI)

Strengthen your skills by implementing EdDSA digital signatures and asymmetric encryption with OpenSSL on live firmware, simulate MITM and replay attacks to test robustness, integrate an enterprise PKI into your OTA pipeline via AWS IoT Core or Azure Device Update, conduct practical security audits on vulnerable binaries, generate certificates and keys for secure deployment, document a cyber incident response plan with automated rollback.

Module 3OTA Updates Implementation: Firmware Integration and Delta Management (Zephyr, Mbed, Custom Bootloaders)

Move to practice by modifying existing bootloaders to support delta OTA with tools like bsdiff and zdelta, integrate OTA APIs into RTOS like Zephyr or Mbed on real hardware, develop an autonomous OTA agent handling resilient downloads and integrity checks, test on simulated fleets with 100 virtual devices, optimize packages to reduce size by 70% using LZ4 compression, produce a deliverable upgradable firmware tested in degraded conditions.

Module 4OTA Updates Deployment: Scaling and A/B Testing (Kubernetes IoT, Balena, Mender)

Master scaling by deploying OTA fleets via Mender or Balena on Kubernetes for IoT, configure A/B testing campaigns to validate updates without global risk, integrate cloud backends AWS Greengrass or Azure IoT Edge for centralized orchestration, simulate deployments on 500+ devices with throttling and canary releases, analyze real-time metrics via Grafana and Prometheus, generate success/failure reports for rapid enterprise iterations.

Module 5OTA Updates Optimization: Monitoring, Rollback, and Advanced Cases (Edge Computing, 5G, ML Inference)

Push your expertise with bandwidth optimization on 5G networks via QoS and multicast, implement intelligent rollbacks with dual-bank and shadow updates, integrate advanced Prometheus/Grafana monitoring to alert on OTA anomalies, explore edge computing cases with live upgradable ML inference, resolve real challenges like blackouts or heterogeneous fleets, finalize a complete red thread project with custom dashboard and certifying strategy for your enterprise.

Methods, materials and delivery

The Training OTA Updates - Deploy Secure Firmware Updates program is delivered onsite or remote (blended-learning, virtual classroom, remote presence). At Learni, an industry-certified training organization, every program is built to maximize skills acquisition regardless of the chosen format.

The trainer alternates between demonstrative, interrogative and active methods (through hands-on labs and/or scenarios). This pedagogical approach guarantees concrete learning that's immediately applicable at work.

Equipment required

For the smooth delivery of the Training OTA Updates - Deploy Secure Firmware Updates program, the following equipment is required:

Mac or PC computers, high-speed fiber internet, whiteboard or flipchart, projector or interactive touch screen (for remote sessions)
Training environments installed on workstations or accessible online
Course materials, hands-on exercises and complementary resources
Post-training access to materials and educational resources

For intra-company training on a site outside Learni, the client commits to providing all required teaching materials (computers, internet, etc.) for the smooth delivery of the program in line with the prerequisites in the communicated program.

* contact us for remote delivery feasibility** ratio varies depending on the program

Skills assessment methods

Assessment of skills acquired during the Training OTA Updates - Deploy Secure Firmware Updates program is performed through:

During training: case studies, hands-on labs and professional scenarios
End of training: self-assessment questionnaire and skills evaluation by the trainer
After training: completion certificate detailing acquired skills

Program accessibility

Learni is committed to making its programs accessible. All our programs are accessible to people with disabilities. Our teams are available to adapt the pedagogical methods to your specific needs. Please contact us for any adjustment request.

Enrollment terms and lead times

Registration is possible up to 48 business hours before the start of training. All our programs are built for corporate L&D budgets and delivered onsite or remotely.

The Learni story

Founded by engineers and learning experts, Learni's mission is to make high-impact tech training accessible to teams everywhere. We work remotely with organizations across the US and Canada, in your time zone, to help teams upskill fast.

Our method

Training quality, guaranteed at every step

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.

Step 1

Rigorous trainer selection

Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.

Triple validation: technical, pedagogical, sectoral.
Minimum rating 4.8/5 over the last 12 sessions.

Step 2

You meet the trainer beforehand

30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.

Live briefing on goals and team context.
Veto right — we swap the trainer for free if needed.

Step 3

Content tailored to your context

No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.

Hands-on cases drawn from your stack and projects.
Program co-written then validated by your team.

Step 4

Continuous quality follow-up

Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.

NPS, knowledge quizzes and skills self-assessment.
Satisfaction guarantee: fully satisfied or free rework.

A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
