Embedded web UI

Pantavisor Web UI: A Quick Guide

This guide explains how to use the web UI for a Pantavisor-enabled device, which lets you view and manage device information.

To access the UI, you’ll first need to find your device’s local IP address (see our previous guide on how to find the device’s IP address). Once you have the IP, open a web browser and navigate to http://<IP>:12368/app.

Transaction

The Home page is where you can view the current state of your device’s software and manage transactions.

On this page, you’ll see:

• Status, Progress, and Revision: These indicate the device’s current state. A Status: DONE and Progress: 100 with Rev: 0 mean the device is in a stable, initial state.
• Begin new transaction: This button starts a new transaction, which is how you manage updates and changes to the device’s software.
• BSP, OS, and SDK sections: These expandable sections display details about the Base System Platform (BSP), Operating System (OS), and Pantavisor SDK, allowing you to see the components that make up your device’s firmware.

Managing Transitions

When you “begin transaction”, you can upload new application packages or change configurations. Once you are satisfied with the changes, you can “commit” them to create a new revision.

Next Steps

Now that you’ve explored the local web UI, you might want to:

• Manage Applications: Learn how to install and remove apps using the UI.
• Remote Access: See how to manage your device from the cloud.

Stats & Config

The Stats & Config page provides a detailed overview of your device’s hardware resources and its configuration settings. This page is divided into two main sections:

Device Stats

This section shows real-time resource usage:

• Ram: Shows the amount of used and total RAM.
• Swap: Displays swap space usage.
• Disk usage: Shows the used and total disk space.
• Reserved: This is disk space reserved by Pantavisor for system operations.

Device Meta & Config

This section displays key configuration information:

• IP Addresses: Lists the IPv4 and IPv6 addresses for each network interface, such as eth0 and lo (loopback).
• Pantahub Status: pantahub.claimed and pantahub.online show whether the device is connected to and claimed on the Pantahub platform. pantahub.state indicates the device’s current connection state (e.g., claim).
• Device Configuration: The Device Config table lists various key-value pairs that define the device’s behavior. These include:
  • creds.host and creds.port: The host and port used for connecting to the Pantahub API.
  • creds.id: The unique ID of the device.
  • creds.prn and creds.secret: The device’s Pantahub Resource Name and secret key for authentication.

Logs

The Logs page is where you can view and troubleshoot system activity.

• Log Fragments: On the left, you can select different log files or fragments to view. These logs are often categorized by component, such as pvwifi (Pantavisor Wi-Fi), pvr-sdk, and the core pantavisor logs.
• Log Output: The main window displays the content of the selected log file. Log entries are timestamped and categorized by severity level, such as DEBUG, INFO, and WARN, making it easier to identify issues. For example, [pantahub] DEBUG entries provide detailed information on the device’s communication with Pantahub. You can see the device’s connection status, configuration settings being loaded, and network operations.
