geky | 17:92a64d43ee61 | 18 | This is a sample program to illustrate the use of the MQTT Client library |
geky | 17:92a64d43ee61 | 19 | on the mbed platform. The Client class requires two classes which mediate |
geky | 17:92a64d43ee61 | 20 | access to system interfaces for networking and timing. As long as these two |
geky | 17:92a64d43ee61 | 21 | classes provide the required public programming interfaces, it does not matter |
geky | 17:92a64d43ee61 | 22 | what facilities they use underneath. In this program, they use the mbed |
geky | 17:92a64d43ee61 | 23 | system libraries. |
