just as the title says, someone of you has had luck integrating Solace messages from an embedded application. I could only find their API to be used under an operating system, not for standalone applications.
Is there any stack or libraries to do the task from a 32bit microcontroller under C/C++?
You could always use MQTT from your embedded platform to connect to Solace.
Different endpoints can use different messaging protocols, so a telemetry reading going in via MQTT can be seamlessly fanned out over JMS and AMQP to different backends.
