A few weeks back, while being at EclipseCon France, I did stumble over a nice little gadget. There was talk from MicroEJ around Java on microcontrollers. And they where showing an IoT related demo based on their development environment. And it seemed they did have Eclipse Paho (including TLS) and Google Protobuf running on their JVM without too much troubles.
Sometimes you write something and then you nearly forget that you did it … although it is quite handy sometimes, here are a few lines of Apache Camel XML running in Eclipse Kura:
While working on Eclipse Kapua, I wanted to do different tests, pushing telemetry data into the system. So I started to work on the Kura simulator, which can used to simulator an Eclipse Kura IoT gateway in a plain Java project, no special setup required. Now that helped a lot for unit testing and scale testing. Even generating a few simple telemetry data streams for simulating data works out of the box.
