1 Using 4G Module EC20 on Android

1.1 Hardware Setup

Connect an EC20 module to a USB to miniPCIe board and connect the board to an ARM board's USB Host. Here is a hardware setup:

Power on the board and you will be able to surf the internet with the 4G module like using an Android phone.

1.2 Activate EC20's GPS Functions

By default GPS functions are disabled in Android. If GPS functions are enabled in Android but no GPS module is detected Android will continuously output log messages. After an EC20 module is connected you can enable GPS functions.
To enable the GPS functions open the "vendor/quectel/ec20/BoardConfigPartial.mk" file and change the following line: 

BOARD_HAS_GPS := false

to 

BOARD_HAS_GPS := true

and recompile Android。
