icraggs | 2:638c854c0695 | 19 | This is a sample program to illustrate the use of the MQTT Client library |
icraggs | 2:638c854c0695 | 20 | on the mbed platform. The Client class requires two classes which mediate |
icraggs | 2:638c854c0695 | 21 | access to system interfaces for networking and timing. As long as these two |
icraggs | 2:638c854c0695 | 22 | classes provide the required public programming interfaces, it does not matter |
icraggs | 2:638c854c0695 | 23 | what facilities they use underneath. In this program, they use the mbed |
icraggs | 2:638c854c0695 | 24 | system libraries. |
