Android-themed look for identifying device information using ADB

Master ADB to Identify WiFi MAC, Product Model and Serial Number Quickly!

Have you ever wondered how to retrieve crucial device information, such as the WiFi MAC address, product model, and serial number of your Android device using a simple tool? Android Debug Bridge (ADB) is a powerful command-line utility that allows you to interact with your Android device from a computer. Using ADB, you can easily extract important device details in a few commands. In this guide, we’ll walk you through everything you need to know about identifying the WiFi MAC, product model, and serial number using ADB commands.

By the end of this post, you’ll be able to quickly fetch these essential details for any connected Android device, making debugging, testing, or managing devices a breeze.

What is ADB and Why Use It for Identifying Device Information?

Android Debug Bridge (ADB) is a versatile command-line tool that allows you to communicate with an Android device. It is part of the Android SDK (Software Development Kit) and is widely used for debugging, testing, and development purposes. ADB is especially helpful for retrieving device information without having physical access to the settings menu.

  • Why Use ADB for Device Information?
  • Quick Access: Retrieve important information without navigating through the device’s settings.
  • Automation: Useful for developers who need to extract device information programmatically.
  • Versatility: ADB provides numerous commands to interact with various parts of the Android system.

How to Set Up ADB on Your System

Before we dive into retrieving the WiFi MAC, product model, and serial number, it’s essential to set up ADB correctly on your system.

Step 1: Install ADB

  • For Windows users:
  1. Download the Android SDK Platform Tools from the official Android developer website.
  2. Extract the downloaded file to a location of your choice.
  3. Add the extracted folder to your system’s PATH environment variable for easy access.
  • For Linux users:
  sudo apt-get install android-tools-adb
  • For MacOS users:
  brew install android-platform-tools

Step 2: Enable USB Debugging on Your Android Device

To use ADB, you must enable USB Debugging on your Android device:

  1. Go to Settings > About Phone.
  2. Tap Build Number multiple times to enable Developer Options.
  3. Go to Developer Options and enable USB Debugging.

Retrieve Device Information Using ADB

Once ADB is set up and your device is connected via USB, you can use the following commands to retrieve the desired information.

1. Identify WiFi MAC Address

To get the WiFi MAC address of your Android device, run the following command:

adb shell ip addr show wlan0
  • Explanation:
  • The command above uses adb shell to access the device’s shell.
  • ip addr show wlan0 shows network information for the wlan0 interface, including the MAC address.
  • The MAC address will be labeled as link/ether.

2. Get the Product Model

To identify the product model of your Android device, use the following command:

adb shell getprop ro.product.model
  • Explanation: The getprop command fetches system properties, and ro.product.model is the property that stores the device model.
  • Output Example: Pixel 5 or Samsung Galaxy S10

3. Retrieve the Serial Number

To retrieve the serial number of the device, run this command:

adb get-serialno
  • Explanation: The adb get-serialno command directly returns the serial number of the connected Android device.
  • Output Example: ABC1234567

Common Issues and Solutions

1. ADB Not Recognized

If you encounter an error like “adb: command not found”, it usually means that ADB is not installed or is not added to your system’s PATH.

Solution: Ensure that ADB is installed and that the platform-tools directory is included in your system’s PATH.

2. Device Not Detected

Sometimes, ADB may not detect your connected Android device.

Solution:

  • Check USB Connection: Make sure the USB cable is working properly and that USB Debugging is enabled.
  • Authorize Your Computer: If prompted, allow USB debugging permissions on your Android device.
  • Restart ADB: Run the following commands to restart ADB services:
  adb kill-server
  adb start-server

Best Practices for Using ADB to Retrieve Device Information

  • Ensure Device is Authorized: Always authorize your computer when prompted to access the device using ADB.
  • Verify USB Connectivity: A loose USB connection can interrupt communication between the device and computer, leading to errors.
  • Check Permissions: Some device information may require elevated permissions. You can use adb root to gain superuser privileges if needed (depending on the device).

Conclusion

Using ADB to identify the WiFi MAC address, product model, and serial number is an efficient way to access critical information without navigating through the Android device’s settings. By mastering ADB commands, you can make your Android development, testing, and debugging processes much more streamlined and effective.

Remember to follow best practices to avoid common pitfalls, and always keep your device secure when using ADB commands.
