wolfMQTT v0.13 Released

wolfMQTT v0.13 is now available for download. This release contains fixes for non-blocking and Arduino.

The wolfMQTT client is a lightweight protocol used commonly in the IoT space and is a pub/sub model. It is written in C from scratch and is based on the MQTT v3.1.1 specification. As a result the code is compact (~4KB) and clean. We’ve taken great care to explicitly check all parameters and input data to ensure reliable and secure operation. The client also integrates with our wolfSSL client to provide TLS for MQTT, which is required for AWS and Azure.

We have examples for connecting to:
* Amazon Web Services (AWS)
* Microsoft Azure IoT Hub
* Firmware Update over MQTT
* Generic MQTT client

The examples support using various operating systems and network stacks such as Linux/Mac/Windows/FreeRTOS/MQX. The wolfMQTT library uses callbacks for the networking so you can implement it for any two of communication interface. We even have an example template for using a UART via the callbacks.

Planned upcoming features:
* Multi-threaded support
* Android and iOS examples
* MQTT-SN (sensor network spec that reduces protocol overhead).
