| 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. |
