This project allows you to use our, more recent, Java modules as simple MQTT clients.
Just use AT Commands - no Java programming needed.

The MQTT client is made possible via the Thales IoT Java AT Command Extensions (JAT).
Both Plain text :1883 and TLS 1.2 secure sockets :8883 Broker connections can be used (even AWS).

You can add new AT Commands to the ELS61 rel 1 "MR" / ELS61 rel 2 / PLS62-W rel 2 and EHSx rel 4 modules. URCs are generated showing broker connections, loss, and reconnections.

Publishing JSON formatted strings is supported, see the attached documentation for the syntax needed.

Publishing HEX formatted binary byte[] strings is supported, see the attached documentation for the syntax needed.
