mfaheem2004 0:0044354f0061 19 * The UbloxATCellularInterface or OnboardCellularInterface uses it
mfaheem2004 0:0044354f0061 20 * to make a simple HTTP connection to a STC IOT server.
mfaheem2004 0:0044354f0061 21 * Progress may be monitored with a serial terminal running at 9600 baud or at https://ksu.aep1.iot.stcs.com.sa
mfaheem2004 0:0044354f0061 22 * The LED on the C030 board will turn green when this program is
mfaheem2004 0:0044354f0061 23 * operating correctly, pulse blue when a sockets operation is completed
mfaheem2004 0:0044354f0061 24 * and turn red if there is a failure.
