Create a wireless route for Raspberry Pi
OpenVPN is a private protocol and requires proprietary clients. Therefore, it is difficult to use OpenVPN on Android (CM9 supports OpenVPN), iOS, and WP8. Combining Raspberry Pi and OpenVPN to build a soft AP can easily solve these problems.
Why is this combination selected?
This project uses Raspberry Pi with ultra-low-cost software radio (SDR) hardware to receive tracking information sent from an airborne S-mode transponder outside millions of miles. The Raspberry Pi is equipped with a smart 3.5-inch TFT display to provide a convenient overvie

1Once the Raspberry Pi system is installed, the "raspi-config" tool appears for the first boot, such as: (if it is not initially started, in command mode, please enter the sudo raspi-config command to bring up this interface.) If you open the desktop's LXT client under the graphical desktop, the sudo raspi-config command can also be used to bring up the tool.
