 The [LoRaWANInterface](https://os-doc-builder.test.mbed.com/docs/development/mbed-os-api-doxy/class_lo_ra_w_a_n_interface.html) provides a C++ API for connecting to the internet over a LoRa network. In this sub-section, we first put light on the API reference for 'LoRaWAnInterface' and then we present an example which can be directly imported to Mbed online compiler.
