 # coreMQTT Client Library
 
-This repository contains the coreMQTT library that has been optimized for a low memory footprint.  The coreMQTT library is compliant with the [MQTT 3.1.1](http://docs.oasis-open.org/mqtt/mqtt/v3.1.1/mqtt-v3.1.1.html) standard.  It has no dependencies on any additional libraries other than the standard C library, a customer-implemented network transport interface, and *optionally* a user-implemented platform time function.  This library is distributed under the [MIT Open Source License](LICENSE).

 This library has gone through code quality checks including verification that no function has a [GNU Complexity](https://www.gnu.org/software/complexity/manual/complexity.html) score over 8, and checks against deviations from mandatory rules in the [MISRA coding standard](https://www.misra.org.uk/MISRAHome/MISRAC2012/tabid/196/Default.aspx).  Deviations from the MISRA C:2012 guidelines are documented under [MISRA Deviations](MISRA.md). This library has also undergone both static code analysis from [Coverity static analysis](https://scan.coverity.com/), and validation of memory safety and proof of functional correctness through the [CBMC automated reasoning tool](https://www.cprover.org/cbmc/).

 @brief MQTT 3.1.1 client library
 
 > MQTT stands for MQ Telemetry Transport. It is a publish/subscribe, extremely simple and lightweight messaging protocol, designed for constrained devices and low-bandwidth, high-latency or unreliable networks. The design principles are to minimise network bandwidth and device resource requirements whilst also attempting to ensure reliability and some degree of assurance of delivery. These principles also turn out to make the protocol ideal of the emerging "machine-to-machine" (M2M) or "Internet of Things" world of connected devices, and for mobile applications where bandwidth and battery power are at a premium.

 This MQTT library implements the client side of the MQTT 3.1.1 protocol. This library is optimized for resource constrained embedded devices. Features of this library include:
 - Fully synchronous API, to allow applications to completely manage their concurrency and multi-threading method.
