PPP Widget (Discontinued): A Tool for Expanding Connectivity

PPP Widget was an innovative application designed to extend the functionality of WiFi-only tablets by enabling them to connect to the internet via a 3G modem stick or a modem-enabled phone. This app allowed users to leverage their Android tablet's USB host feature to turn it into a versatile device capable of accessing mobile broadband networks. However, due to limitations in its development and compatibility with newer Android versions, the app has been discontinued, with users encouraged to transition to its successor, PPP Widget 2.

Key Features and Purpose

The primary purpose of PPP Widget was to bridge the gap between WiFi-only tablets and mobile broadband connectivity. It achieved this by acting as a frontend for the PPP (Point-to-Point Protocol) daemon, which facilitated internet access through almost any USB device with modem capabilities. For users with 3G sticks, the app included the usb_modeswitch tool, which automatically converted the device into modem mode in most cases. Whether you were using a standalone 3G stick or a smartphone tethered via USB, PPP Widget aimed to simplify the process of establishing a reliable internet connection.

However, there were certain prerequisites for using the app effectively. First and foremost, root access was required, along with a Superuser or SuperSU app to grant administrative privileges. Additionally, users needed an OTG (On-The-Go) adapter to enable USB host functionality on their tablets. In some cases, a powered USB hub was also necessary to ensure sufficient power supply for the connected devices. Furthermore, specific devices like Samsung models required additional kernel drivers to ensure compatibility.

Limitations and Recommendations

Despite its potential, PPP Widget faced several challenges. One significant limitation was the lack of guaranteed compatibility across all Android-modem combinations. While the app worked well for many users, others encountered issues such as receiving a "No driver" message. The developers emphasized that these problems were not caused by the app itself but rather by hardware or firmware limitations. They recommended consulting the FAQs on the developer's website (http://www.draisberghof.de/android/pppwidget.html) for troubleshooting tips.

Another critical issue arose with newer Google devices running stock Android versions greater than 4.2. These devices had kernel module loading disabled, making it highly unlikely for PPP Widget to function correctly. For such users, transitioning to PPP Widget 2 was strongly advised. Unlike its predecessor, PPP Widget 2 did not rely on kernel drivers, making it compatible with Android 5.0 (Lollipop) and later versions.

Developer's Perspective

The developers of PPP Widget were transparent about its limitations and encouraged users to contribute to its improvement. They acknowledged that testing the app on multiple devices was beyond their capacity and urged users who encountered issues to provide constructive feedback rather than leaving negative comments. The app was entirely free, with no ads or data collection, reflecting the developers' commitment to providing a lightweight and unobtrusive solution for expanding connectivity.

In summary, PPP Widget was a pioneering tool for users seeking to enhance their WiFi-only tablets' functionality. Although it has been discontinued, its legacy lives on in PPP Widget 2, which builds upon its foundation while addressing its shortcomings. For those still using PPP Widget, upgrading to its successor remains the best course of action to ensure continued support and compatibility with modern Android systems.
