You can connect with virtually all optional parameters the protocol supports, including Will Message. The only exception to the rule is the clean session flag. This is not tested and may or may not work as intended. - Publish QoS level 0, 1 and 2 messages. All protocol supported parameters are also supported, such as retained messages and other options. - Subscribe on QoS level 0, 1 and 2 topics. Connection handling will be done automatically, no need to fiddle with PingRequests and alike. - Filters of topics are those used on the protocol itself, which eliminates the likeliness of bugs that may occur from incorrectly parsing such filters. This package uses sockets to communicate (a)synchronously with the broker. If you don't want this, you are free to create your own client, for which you'll just have to implement an interface. Examples -------- [](#examples) This package has many examples detailing the many things you can do with it. Please check the [examples directory](https://github.com/unreal4u/mqtt/tree/master/examples) for more information. In case of questions or doubt, [open up an Issue](https://github.com/unreal4u/mqtt/issues/new) or submit a [Pull Request](https://github.com/unreal4u/mqtt/pulls) if you feel the need to clarify, correct or add more examples.
