How to Access ODU WEB UI on Android

This guide explains how to find the IP address of the ODU (Outdoor Unit) and access its WEB UI. It provides two methods:

  1. Primary Method: Using Termux and nmap for fast command-line scanning.
  2. Alternative Method: Using the PingTools Network Utilities app if Termux fails.

📋 Prerequisites

Ensure you have the following apps installed on your Android device:

🔧 Setup Instructions

1. Set Up J** Apps

  1. Install J** Apps

    • Install J** Field Diagnostic App and J** Home App from the Google Play Store.

  2. Login

    • Open J** Home App.
    • Log in using your J** account credentials.

  3. Scan QR Code

    • Open the J** Field Diagnostic App.
    • Scan the QR code on the ODU.

  4. Pair & Enable Bluetooth Tethering

    • When prompted, open J** Home App.
    • Follow instructions to pair and enable Bluetooth tethering.
    • Keep both apps running in the background.

🔍 Method 1: Using Termux (Preferred)

Step A: Launch Termux

Open Termux and run:

ifconfig

Look for a bt-pan interface, e.g.:

bt-pan: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
      inet 192.168.44.1  netmask 255.255.255.0  broadcast 192.168.44.255

If bt-pan is not visible, make sure both J** apps are open and tethering is active.

Step B: Run Nmap to Discover ODU IP

Run:

nmap -p 443 192.168.44.0/24

Example output:

Nmap scan report for 192.168.44.1 (gateway)
443/tcp closed https

Nmap scan report for 192.168.44.150 (ODU)
443/tcp open https

The IP with port 443 open (like 192.168.44.150) is your ODU's address.

📱 Method 2: Using PingTools (If Termux Fails)

  1. Install the App

  2. Open Subnet Scanner

    • Tap menu icon (☰) > "Subnet Scanner"

  3. Configure IP Range

    • Tap settings icon (⚙️) > Manual Configuration
    • Set:
      • Start IP: 192.168.44.0
      • End IP: 192.168.44.255
    • Tap Save

  4. Start Scan

    • Tap Scan to begin.
    • Look for a device with port 443 open or labeled ODU

🌐 Accessing the ODU WEB UI

  1. Open a browser on your phone.

  2. Go to:

    https://<ODU-IP>

    Example:

    https://192.168.44.150

  3. Tap "Advanced > Proceed" if a security warning appears.

🛠️ Troubleshooting

  • Ensure Bluetooth tethering is enabled.
  • Keep J** apps running in the background.
  • If Termux shows no bt-pan, restart Bluetooth and reconnect.
  • Retry scanning via Termux or use PingTools as a fallback.

✅ Use Termux for speed and precision. Use PingTools for a user-friendly visual method.
