• Two OpenHarmony-compatible devices (e.g., Dayu200 Development Board and OpenHarmony Developer Phone)
• Valid network connection
• Proper permissions (ACCESS_SERVICE_DM and DISTRIBUTED_DATASYNC)

• Discover nearby devices on the same networkAdd commentMore actions
• Authenticate and pair discovered devices using a PIN code
• Send command from controller to receiver in real time
