u-blox
Implementation of the CellularInterface for u-blox C027 and C030 (non-N2xx flavour) modems that uses the IP stack on-board the cellular modem, hence not requiring LWIP (and so less RAM) and allowing any AT command exchanges to be carried out at the same time as data transfers (since the modem remains in AT mode all the time). This library may be used from mbed 5.5 onwards. If you need to use SMS, USSD or access the modem file system at the same time as using the CellularInterface then use ublox-at-cellular-interface-ext instead.

| 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. |
