The Client class requires two classes which mediate access to system interfaces for networking and timing. As long as these two classes provide the required public programming interfaces, it does not matter what facilities they use underneath. In this program, they use the mbed system libraries. */ #include "mbed.h" //------------------------------------------------------------------------------------ // You need to configure these cellular modem / SIM parameters. // These parameters are ignored for LISA-C200 variants and can be left NULL. //------------------------------------------------------------------------------------ #include "MDM.h" //!
