1. Sync button

Step	Description
Idle	Initializes the sync process.
getVHInfo	Retrieves the hub (mobile) configuration and saves it to settings.
scanDevices	Scans devices for 45 seconds and sorts them by RSSI signal strength.
updateDeviceList	Connects to and validates detected devices.
getRemoteCommand	Fetches and executes remote commands from the server on the device.
downloadDeviceData	Downloads device data and images from selected devices.
uploadRNLogsDB	Uploads logs to the server.
uploadRemoteCommandData	Uploads remote command execution data.
uploadDeviceData	Uploads downloaded device data.
uploadImages	Uploads captured images to the server.
reschedule	Schedules the next service run.

2. Action icon

Tapping the action icon opens a bottom sheet with scan options:

Step	Option	Description
1	Action icon	Located at the top right, next to the Sync icon. Opens the scan options.
2	Start Scan	Initiates a standard BLE scan. Nearby devices appear with advertisement data.
3	Start DFU Scan	Scans for devices in DFU (Device Firmware Update) mode for firmware upgrades.
4	Stop Scan	Stops any ongoing scan.

4. Device list

The Device List shows key information for each device: device ID, BLE RSSI, GSM strength, temperature, and connection status.

4.1 Device summary

1. Avatar

   
   • The circular icon shows the first character of the device ID (for example, "Z" for CVZ-030300204572).
   • Tap or long-press to open device-specific actions:

     • Connect — initiate a real-time connection, run commands, and show responses on the device detail screen.

     • Take Picture — trigger the device camera, download the image, upload it, and preview.

     • Cancel — close the action menu.

       Take Picture process: the app connects to the device, triggers the Take Picture command, reconnects to download the image, and then displays a preview.

2. Device Serial: A unique identifier assigned to each device. Example: CVZ-030300204572.

3. BLE RSSI: Displays Bluetooth Low Energy (BLE) signal strength.

4. Connectivity indicator (GSM strength): A red icon indicates poor RSSI; a green icon indicates good RSSI.

5. Last sync date & time: Shows the last successful communication timestamp (for example, 07/04/2025 17:35:57).

4.2 Device status details

This section provides detailed status information such as reading timestamps, network info, temperature, and battery level.

1. Last door capture time : Timestamp of the latest door capture.

2. Network type : Current network connection type (for example, GSM).

3. Events / Image : Indicates whether events or images have been recorded or triggered.

4. Temperature : Latest recorded temperature (for example, 51.8 °F).

5. Data status : Status of the last data communication (for example, "Successfully sent").

6. Battery : Battery level is shown with an icon; a green dot indicates healthy battery status.

5. Footer
