Qt in IoT context - connected alarm clock
summary
A connected alarm clock running on an i.MX6 uses Qt5 graphics (OpenGL, shaders, multitouch) and a cloud gateway to store alarms and fetch weather/news via HTTP+JSON, parsed with QNetworkAccessManager and QJsonDocument. Device controls a Wi‑Fi bulb on a fixed IP using QUdpSocket to simulate a sunrise; remote triggers use a host‑restricted QTcpServer or a broker (publish/subscribe) with QMQTT/Mosquitto. Security uses QSslSocket, input validation, and firewall/patching; the demo lamp powers on when the alarm rings.
