Kimmo Vaisanen 738f9fbcf6 Cellular: Disable AT traces when mbed-trace is disabled Earlier if mbed-trace was disabled but debug-at enabled, some AT trace codes were still enabled causing unnecessary code size increase. This commit fixes the issue that AT debug trace code is enabled only when both mbed-trace.enable and cellular.debug-at are enabled. Reduces binary size by about ~340bytes when mbed-trace is disabled but debug-at enabled.		2020-04-16 16:24:40 +03:00

Mbed cellular connectivity

This is the Github repo for Mbed cellular connectivity:

framework/
    API         Application Programming Interface for cellular connectivity
    AT          AT implementation based on 3GPP TS 27.007 specification
    common      Common and utility sources
    device      Implementation of cellular device and state machine
    targets     Vendor specific cellular module adaptations

Note: Application developers should use only the API folder.

Known limitations

Please note that this is a first release of Cellular framework and is subject to further development in future.

Supported modules

You can find currently supported cellular modules in the framework/targets/ folder, where we also add support for new cellular modules.

Cellular configuration

You can change cellular defaults in the mbed_lib.json configuration file.

Debug traces

You can define the debug tracing level in the mbed_app.json configuration file:

"target_overrides": {
    "*": {
        "mbed-trace.enable": true,
        "platform.stdio-convert-newlines": true,
        "platform.stdio-baud-rate": 115200,
        "platform.default-serial-baud-rate": 115200
    }
},
"config": {
    "trace-level": {
        "help": "Options are TRACE_LEVEL_ERROR,TRACE_LEVEL_WARN,TRACE_LEVEL_INFO,TRACE_LEVEL_DEBUG",
        "macro_name": "MBED_TRACE_MAX_LEVEL",
        "value": "TRACE_LEVEL_INFO"
    }
}

Greentea tests

Cellular connectivity can be tested with generic Mbed OS netsocket and network interface tests found in Mbed OS root TESTS directory. For more information, see TESTS/netsocket/README.md and TESTS/network/interface/README.md.

Unit tests

Cellular unit tests are in Mbed OS root UNITTESTS/features/cellular.
