Learning objectives

  • Master the fundamental concepts of OTA firmware for embedded systems and connected devices
  • Compare different OTA update methods and protocols to choose the most suitable for your projects
  • Integrate an end-to-end solution, from secure bootloader to server distribution infrastructure
  • Implement best practices to ensure the integrity and security of updates
  • Develop and test a complete OTA flow on real hardware (ESP32, STM32 or equivalent)
  • Anticipate and manage errors, rollbacks, and backward compatibility during updates

Our social commitment

A school kit donated to a child for every training

To fight inequalities in access to education, Learni donates a complete school kit to a child in need for every training booked. You build your skills, a child heads back to school.

  • Backpack, notebooks and essential supplies
  • Distributed through our partner charities
  • Included, at no extra cost to you

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.

Don't let this gap widen

Why this program matters

  • Without mastery of secure OTA firmware updates for connected devices, 75% of IoT cyberattacks exploit unpatched vulnerabilities, according to ENISA reports.

  • A breach costs a company an average of 4,2 millions d'euros, with prolonged downtimes impacting 30% of connected deployments.

  • Your project risks sudden operational shutdowns, massive product recalls, and reputation erosion, jeopardizing contracts and career.

  • Each month without expertise exposes you to unavoidable critical vulnerabilities.

Module 2Security, Integrity, and OTA Chain Design

• Securing OTA flows: authentication, encryption, digital signatures • Token management, trust chains, and certificates • Strategies against attacks (downgrade, man-in-the-middle) • Building an OTA-ready firmware: version management, rollback, atomicity • Presentation of open-source frameworks (MCUBoot, ESP-IDF OTA, Mbed, etc.)

Module 3Integration, Deployment, and Update Management

• Setting up an OTA server (AWS IoT Device Management, Mender, balena, custom server) • Full testing: upload, verification, application, and rollback on real target • Mass deployment strategies: batching, group management, monitoring • Handling error cases, log management, and supervision • Feedback from experience: real deployments, maintenance, and long-term support

Evaluation method

  • Knowledge assessment MCQ at the end of the training
  • Continuous assessment through practical exercises on microcontrollers
  • Realization of an OTA proof-of-concept on a real device

Learning method

  • Interactive courses with technical demonstrations
  • Practical coding labs on IoT platform (remote connection to ESP32/STM32 provided to each participant)
  • Real case studies and situational workshops
  • Detailed course materials, sample scripts, security checklists

Methods, materials and delivery

The Training Over-the-Air (OTA) Firmware Updates for Connected Devices: Mastering Security and Efficiency 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 Over-the-Air (OTA) Firmware Updates for Connected Devices: Mastering Security and Efficiency 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.

Skills assessment methods

Assessment of skills acquired during the Training Over-the-Air (OTA) Firmware Updates for Connected Devices: Mastering Security and Efficiency 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.

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.
