Hands-On Embedded Programming with C++17

Main

The main source file and with it the application entry point is pretty uneventful:

#include "ota_core.h"void onInit() {    // }void init() {         OtaCore::init(onInit); }

With the OtaCore class containing the main application logic, we merely call its static initialization function while providing a callback function if we wish to execute any further logic after the core class has finished setting up the network, MQTT, and other functionality.
