Web Server Guide

Learn how to upload and manage EPUB files over Wi-Fi.

Overview

CrossPoint Reader includes a built-in web server that lets you:

  • Upload EPUB files from any device on the same Wi-Fi network
  • Browse and manage files on the SD card
  • Create folders to organize your e-book library
  • Delete files and folders
  • Direct book download (v1.2.0): Download books from the SD card to your browser through the web UI
  • WebDAV support (v1.1+): Mount the device as a network drive in macOS Finder, Windows Explorer, Cyberduck, and similar clients

Requirements

  • A CrossPoint Reader device
  • A Wi-Fi network
  • A computer, smartphone, or tablet connected to the same Wi-Fi network

Step 1: Open the Wi-Fi Screen

  1. From the main menu or file browser, open the Settings screen
  2. Select the Wi-Fi option
  3. The device automatically begins scanning for available networks

Step 2: Connect to Wi-Fi

View Available Networks

When the scan finishes, the device displays available Wi-Fi networks with the following indicators:

  • Signal strength bars (||||, |||, ||, |) indicate connection quality
  • * symbol means the network is password-protected (encrypted)
  • + symbol means saved credentials are available

Select a Network

  1. Use the Left/Right (or Prev/Down) buttons to scroll the network list
  2. Press OK to select the highlighted network

Enter the Password

If the network requires a password:

  1. An on-screen keyboard appears
  2. Use the navigation buttons to select characters
  3. Press OK to enter each character
  4. When finished, choose the Done option on the keyboard

Note: If you have connected to this network before, the saved password is used automatically.

Step 3: Connection Established

Once connected, the screen shows:

  • Network name (SSID)
  • IP address (for example, 192.168.1.102)
  • Web server URL (for example, http://192.168.1.102/)

Important: Make a note of the IP address — you will need it to reach the web interface from a computer or smartphone.

Step 4: Open the Web Interface

From a Computer

  1. Verify your computer is on the same Wi-Fi network as the CrossPoint Reader
  2. Open a web browser (Chrome is recommended)
  3. Type the IP address shown on the device into the address bar
  4. Press Enter

From a Smartphone or Tablet

  1. Verify your phone or tablet is on the same Wi-Fi network as the CrossPoint Reader
  2. Open a mobile browser (Safari, Chrome, etc.)
  3. Type the IP address into the address bar
  4. Tap Go

Step 5: Use the Web Interface

Troubleshooting

Device Not Reachable on the Network

Problem: The browser shows "Cannot connect" or "This site can't be reached".

  • Verify both devices are on the same Wi-Fi network
  • Confirm the IP address was entered correctly
  • Include http:// at the start of the address
  • Try disabling any active VPN

Connection Drops or Times Out

  • Move closer to the Wi-Fi router
  • Check the signal strength on the device (|| or higher recommended)
  • Avoid interference from other devices

Upload Fails

  • Confirm the file is a valid .epub file
  • Verify the SD card has enough free space
  • Test with a smaller file first
  • Refresh the browser page and try again

Security Notes

  • The web server runs on port 80 (standard HTTP)
  • No authentication is required — anyone on the same network can access the interface
  • The web server is reachable only while the Wi-Fi screen shows "Connected"
  • Leaving the Wi-Fi screen automatically stops the web server
  • For security, use only on trusted private networks

Exit Wi-Fi Mode

After you finish uploading files:

  1. Press the Back button on the CrossPoint Reader
  2. The web server stops automatically
  3. Wi-Fi disconnects to save battery
  4. The previous screen returns

Uploaded files are immediately available in the file browser!
