cMQTT is a free software library to implement the MQTT Client.

The functions included in the library have been derived from the MQTT Protocol Reference Guide which can be obtained from MQTT web

The license of cMQTT is LGPL v2.1 or later.

The library design refer to Aliyun IOT SDK,so it is very stable.

The library is written in C and designed to run on Linux, Mac OS X, FreeBSD, ARM embed platform and Windows.

you can compile the library or direct put the source code into your project.

If you want to compile the library,just run the usual dance,

1. ./configure.sh

2. make isntall

the default compile is gcc, if your platform need cross compile(example: arm-linux-gnueabihf),just run:

1. ./confgure.sh arm-linux-gnueabihf

2. make install

After compile the bibrary, in current director,will create libcMQTT director,you need copy libcMQTT.so to your platform(ex. linux platform is /usr/lib)

Some tests are provided in test directory, you can freely edit the source code to fit your needs.

See test/README for a description of each program.

For a quick test of cMQTT, you can run the following programs in two shells:

./single-client

./multi-client

Attention, before run the programs, you need start a MQTT broker, the example programs configure params:

username: admin password: password

host: 127.0.0.1

port: 1883
