This tutorial extends the connection of IoT devices connecting to FIWARE to use an alternate transport. The UltraLight 2.0 IoT Agent created in the previous tutorial is reconfigured to communicate with a set of dummy IoT devices which transfer secure messages over the IOTA Tangle. An additional gateway component is added to the architecture of the previous MQTT tutorial to allow for secure indelible transactions across a distributed ledger network.

The tutorial is mainly concerned with the architecture of the custom components, but uses cUrl commands where necessary, and is also available as

Postman documentation.
