LoRaWAN in theory and practice: A trip through Munich

LoRaWAN in theory and practice: A trip through Munich

LoRaWAN (Long Range Wide Area Network) is becoming increasingly popular, thanks in part to public networks such as The Things Network, which allow users to dispense with their own gateways. LoRaWAN also promises potential in terms of range and energy efficiency. But how does the standard perform in practice?

The aim of the presentation is to shed light on the technical background and demonstrate how practicable LoRa is in the field using real tests. It will be shown how the standard behaves in urban and rural areas, how differences in height of the gateway and different antennas influence the transmission quality.

LoRaWAN in Theorie und Praxis: Ein Ausflug durch München

LoRaWAN (Long Range Wide Area Network) erfreut sich wachsender Beliebtheit, dazu tragen unter anderem öffentliche Netzwerke wie The Things Network bei, die ermöglichen, auf eigene Gateways zu verzichten. Potenzial verspricht LoRaWAN auch in den Punkten der Reichweite und Energieeffizienz. Aber wie verhält sich der Standard in der Praxis?

Ziel des Vortrags ist es, die technischen Hintergründe zu beleuchten und an realen Versuchen zu demonstrieren, wie praktikabel LoRa im Feldeinsatz ist. Es soll gezeigt werden, wie sich der Standard im urbanen und ländlichen Raum verhält, wie Höhenunterschiede des Gateways und unterschiedliche Antennen die Sendequalität beeinflussen.

Advanced System Profiling, Tracing and Trace Analysis with Perfetto in Android and Yocto

Together with my colleague Stefan Lengfeld.

Tracing is a capable mechanism for deep system analysis and profiling with a minimal overhead. By recording defined system events, in Linux but also Android, tracing can be used to analyze concurrency or latency issues, for example. Android’s systrace tool made it easy to analyze and correlate traces and events due to a graphical UI, in order to help developers identify performance bottlenecks. The successor to this advanced and convenient tool is called Perfetto. It’s available for pure Linux too, and part of Yocto (meta-oe) since Langdale now. In the talk, we’ll have a look into

USB Updates - Challenges, Approaches and Practical Tips

Over-the-air updates have established themselves as the standard for networked devices, but the effort involved in operating the server side is not always commensurate with the benefits. In such cases, the supposedly simple and quick solution of implementing updates via USB is often chosen. But is it really always that uncomplicated? What considerations are necessary to implement USB updates effectively?

This presentation provides an insight into the challenges of USB updates and presents solutions and practical tips for successful implementation. Find out which aspects need to be considered in order to optimize USB updates and ensure a smooth process

Patching Unpatchable Files

Patching Unpatchable Files

In the Yocto world, the .bbappend file is a well-known and documented mechanism for altering recipe files, and an essential part of daily operations. While not common, there are instances where it becomes necessary to modify other file types, such as .inc or .bbclass, which do not offer an equivalent append mechanism. This session will summarize various strategies for effectively handling these file types when patching cannot be avoided.

In my recent presentation at the Yocto Developer Day in Vienna, I mentioned using the KAS patch mechanism for minor modifications to files like .inc or .bbclass, where the Yocto internal overwriting mechanism via .bbappend files does not apply. Initially intended as a helpful side note on how I navigated a few unique situations, this part quickly escalated into the most discussed segment of the talk. Half of the attendees I spoke with found it valuable, while the other half expressed strong objections.
