The Zephyr Project community is heading to Buenos Aires, Argentina!
Join us on Saturday, September 19, 2026, for an in-person Zephyr Project Meetup organized by Iomico. The event is open to developers, engineers, contributors, students, technology professionals, and anyone interested in open source, embedded systems programming, and software development. Whether you are an experienced Zephyr developer or are just beginning to explore embedded technologies, you are welcome to join.
About the Organizer: Iomico
iomico is a custom IoT development company with headquarters in Olympia, WA (US), and engineering hubs in Warsaw (Poland) and Buenos Aires (Argentina). They offer custom software development for IoT, providing comprehensive solutions.
What to Expect
The meetup will feature technical presentations about products running Zephyr, subsystems, practical development experiences, and features you may not have explored yet. Attendees will also have opportunities to ask questions, exchange ideas, and connect with members of the local open source and embedded systems community.

11:10 am – 11:40 am: When the Comm Stack Is a Blob: Integrating a Closed Protocol into a Zephyr Application, Using Amazon Sidewalk as the Case Study – Martin Moya, Embedded Systems Engineer, Focus
Sooner or later most developers hit the same wall: a vendor hands a protocol stack or application as prebuilt libraries and a thin abstraction layer, and it has to live inside an otherwise open application without letting it dictate the architecture. Amazon Sidewalk is an unusually clear example. The protocol is owned and licensed by Amazon, the stack ships as binaries, and on Nordic hardware it reaches you through a Zephyr-based platform abstraction layer you can read and patch.
This talk is a report on actually doing it outside the US, where the network has not been deployed yet and the bench setup follows Amazon’s documented non-US testing path. The recurring problem is attribution: when something misbehaves, deciding whether the fault is in the application, in the glue layer, or inside a binary that it is not possible step into, and what instrumentation must be built or rely on to answer that quickly rather than by bisection.
The second is architecture under flash pressure: the stack is large, DFU OTA has to fit alongside it, and that constrains the slot layout, bootloader configuration, how much application can be afforded and if the system can rely on using the communication interfaces independently of the stack. This presentation shows what those constraints looked like in practice, what the integration costs in flash, RAM and average current, and how to run CI against a stack that cannot be built from source.
This presentation finishes by comparing it against Zephyr’s in-tree LoRaWAN stack on the same radio and the same board. Where the difference is not the protocol but what you can do when it breaks. The Sidewalk specifics are the example; the takeaways are meant to transfer to any binary-blob integration developers have to deal with.
11:45 am – 12:15 pm: Bluetooth Channel Sounding Performance – Mariano Miguel Franceschetti, Embedded Engineer, Iomico
This presentation narrates a Bluetooth Channel Sounding performance test using Zephyr as the OS for the chosen MCUs. It depicts multiple tests to assess BLE CS performance under different circumstances and radio configurations.
12:20 pm – 12:35 pm: Break Time
12:35 pm – 1:05 pm: Nodo lorawan multipropósito – Portabilidad de firmware embebido entre plataformas con Zephyr RTOS – Maximiliano Graf, SW engineer – Embedded Systems Specialist, INVAP SAU – FIUBA
This academic work presents the implementation of a LoRaWAN class A node using Zephyr RTOS, with a particular focus on software portability across different hardware platforms. It also explores the challenges and solutions involved in using development boards that are not officially supported by Zephyr.
1:10 pm – 1:25 pm: Leveraging the Zephyr Shell for Hardware Bring-Up, Testing, and Provisioning – Facundo Zingarelli, Embedded Software Engineer, Iomico
The Zephyr’s Shell subsystem is typically used for manual UART debugging, but it can also be used for board bring-up, factory testing, and provisioning. This talk shares an implementation approach for a custom Shell that unifies these behind a single API, significantly easing the complementary software a project can sometimes need around it. Examples: GUIs for calibration, data backups, provisioning, etc.
1:25 pm – 1:30 pm: Closing Note
1:30 pm – 2:00 pm: Networking

About the Zephyr Community Meetups
This meetup is part of the Zephyr Community Meetup Series, a collection of local gatherings hosted by community members with support from the Zephyr Project.
These events provide a welcoming space for developers, students, researchers, and embedded systems enthusiasts to exchange technical knowledge, present real-world projects, discuss challenges, and build stronger local open source communities.
Whether you are based in Buenos Aires, Argentina, or another part of the world, we encourage community members, companies, universities, and developer groups to get involved.
Reach out to us and explore how you can bring Zephyr to your community and make a difference in the world of IoT development.
To keep up to date about the project, subscribe to the Zephyr quarterly newsletter or connect with us on @ZephyrIoT, Zephyr Project LinkedIn or the Zephyr Discord Channel to talk with community and TSC members.
We look forward to seeing everyone in Buenos Aires, Argentina!
