RobMeades 0:7ccf0e7e8a83 24 *
RobMeades 0:7ccf0e7e8a83 25 * This uses the cellular-tuned IP stack that
RobMeades 0:7ccf0e7e8a83 26 * is on-board the cellular modem instead of the
RobMeades 0:7ccf0e7e8a83 27 * LWIP stack on the mbed MCU.
RobMeades 0:7ccf0e7e8a83 28 *
RobMeades 0:7ccf0e7e8a83 29 * There are three advantages to using this mechanism:
RobMeades 0:7ccf0e7e8a83 30 *
RobMeades 0:7ccf0e7e8a83 31 * 1. Since the modem interface remains in AT mode
RobMeades 0:7ccf0e7e8a83 32 * throughout, it is possible to continue using
RobMeades 0:7ccf0e7e8a83 33 * any AT commands (e.g. send SMS, use the module's
RobMeades 0:7ccf0e7e8a83 34 * file system, etc.) while the connection is up.
RobMeades 0:7ccf0e7e8a83 35 *
RobMeades 0:7ccf0e7e8a83 36 * 2. The UbloxATCellularInterfaceExt class can
RobMeades 0:7ccf0e7e8a83 37 * be used to perform very simple HTTP and FTP
RobMeades 0:7ccf0e7e8a83 38 * operations using the modem's on-board clients.
RobMeades 0:7ccf0e7e8a83 39 *
RobMeades 0:7ccf0e7e8a83 40 * 3. LWIP is not required (and hence RAM is saved).
RobMeades 0:7ccf0e7e8a83 41 *
RobMeades 0:7ccf0e7e8a83 42 * The disadvantage is that some additional parsing
RobMeades 0:7ccf0e7e8a83 43 * (at the AT interface) has to go on in order to exchange
RobMeades 0:7ccf0e7e8a83 44 * IP packets, so this is less efficient under heavy loads.
RobMeades 0:7ccf0e7e8a83 45 * Also TCP Server and getting/setting of socket options is
RobMeades 0:7ccf0e7e8a83 46 * currently not supported.
