There are various software libraries that provide MQTT communication capability, and they differ in many aspects such as the protocol versions and features supported, target platforms, licensing etc. OPC Labs software has uses pluggable MQTT communication packages, and therefore you can decide which of these libraries to use. Each MQTT library is wrapped in a communication package, which provides interface to the rest of OPC Labs software.
The available MQTT communication packages are described in the table below, together with the underlying software (library) they use. The table also contain columns for MQTT libraries for which no communication package is available yet, but is in consideration or development.

Currently, we recommend to use the OpcLabs.MqttNet communication package, and it is set as default. The underlying library has most features. You can switch to a different communication package if you like (see Using communication packages). You can even develop your own communication package if needed (contact us for information to that).
For details on how to work with a particular communication package (such as what is the format of the URL strings used, or how to configure it), see the links in the Documentation row under Communication package in the table above.
