icraggs 2:638c854c0695 18 This is a sample program to illustrate the use of the MQTT Client library
icraggs 2:638c854c0695 19 on the mbed platform. The Client class requires two classes which mediate
icraggs 2:638c854c0695 20 access to system interfaces for networking and timing. As long as these two
icraggs 2:638c854c0695 21 classes provide the required public programming interfaces, it does not matter
icraggs 2:638c854c0695 22 what facilities they use underneath. In this program, they use the mbed
icraggs 2:638c854c0695 23 system libraries.
