AP to PPPoS example

Overview

This example focuses on the networking part, enables forwarding packets between network interfaces. It creates a WiFi soft AP, which uses NAT to forward packets to and from the PPP network interface.

Specific network DCE

Note, that this example could use of a minimal Network DCE, defined in the network_dce.cpp file. Please set EXAMPLE_USE_MINIMAL_DCE to y in order to demonstrate this functionality.

By default, this example simply connects to the PPP server using a supported device with C-API modem interface.

This example however, doesn't rely on sending specific AT commands, just the bare minimum to setup the cellular network. Thus, if the EXAMPLE_USE_MINIMAL_DCE option is enabled, we directly inherit from the ModuleIf and implement only the basic commands. Also, to demonstrate the dce_factory functionality, a new NetDCE_Factory is implemented for creating the network module and the DCE.
