Data Communication Based on MQTT in a Polymer Extrusion Process

This work proposes a flexible method for data communication between a film extrusion system and monitoring devices based on a message protocol called Message Queuing Telemetry Transport (MQTT). The protocol in this work allows building a flexible data communication structure for a Polymer processing machine by employing a publisher subscriber…

A Standardized, Specification-Driven API Lifecycle

Transcript Lane: I’d like to share with you a high level view of why API specifications matter. How OpenAPI, AsyncAPI, JSON Schema and others are helping us standardize and deliver API lifecycle in a way that the machines understand. Also, allows us humans to better communicate, collaborate, and move forward…

TLS in nR5 SDK 17.1.0 – Nordic Q&A – Nordic DevZone

Hello, I’m using the nR5 SDK 17.1.0 and my goal is to implement a TLS client connection between a nRF52840 and an MQTT broker – I have a Wiznet 5500 set up for the TCP stack via SPI. This works well for not secure connections. I’ve since reduced my scope to simply having a…
