Create XOD MQTT node library based on PAHO Library

We are creating an IoT-System based on Android Controllers. These are meant to be programmed with the visual programming language XOD ([login to view URL]). At the moment there is no MQTT nodes library for XOD. Though the standard Arduino boards including well-known ethernet shield W5500 have been implemented as standalone libs already. Jobdescprition: - Implement PAHO MQTT Arduino library ([login to view URL]) into XOD - Create Nodes to connect to a broker (keep the connection alive continuously) - The connection should use username and password and be ssl encrypted (as its possible with PAHO lib) - Create node to connect to broker - Create node to subscribe topics - Create node to publish topics
