Lingkai Dong dca2aa79a0 Unit tests: Remove redundant CMake target mbed-headers-base 
Individual libraries' `target_h` stub headers have now all been moved
from `mbed-headers-base` to `mbed-headers-<library>`.

Note: Even though headers previously in `target_h` are technically
stubs/fakes too, they are used by not only unit tests but also regular
libraries when compiled for unit tests, because no target-specific HAL
implementation exists in this case. In order for regular library
sources to pick up `target_h` headers, those headers must

* have the same names as regular headers
* appear first in include paths

This is why those headers are part of `mbed-headers-<library>` and not
`mbed-stubs-<library>`. Before this refactoring, `mbed-headers-base`
was the first in unit tests' include paths.

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/connectivity/cellular.

Dependency with netsocket

If you create a .mbedignore file with

connectivity/cellular*
connectivity/drivers/cellular*

MBED_CONF_CELLULAR_PRESENT will not be set
