HS-OS Android kiosk control panel
An Android application that turns a device into a dedicated full-screen control panel with a TCP service for telemetry from ESP32 nodes.
The problem
An Android device can serve as a dedicated operator panel if it maintains a focused interface and receives data from multiple nodes.
Solution and data flow
The application combines a kiosk interface, launcher and background services. A TCP server accepts concurrent clients with per-client workers, parses JSON telemetry and forwards connection events and readings to the UI and diagnostic log.
Implementation and challenges
The project includes boot handling, screen wake behavior, network controls and client status. It targets Android 6.0; network operations depend on device permissions and system setup. The implemented work is an application and operator panel, not a new kernel or operating system.
Skills developed
Android lifecycle management, bound and background services, concurrent TCP sockets, JSON telemetry, event-driven UI updates and kiosk design.
