Hi,
    The nanopi 2 fire has a serial demo in android system that friendlyelec
provided ,you can refer the demo to test the serial.

    You can clone the code in github: git clone
https://github.com/friendlyarm/android_SerialPortDemo.git 
 
     In nanopc-t3 ,the serial's device name is as UART3->/dev/ttySAC3.

Attention,you need to use system permissions when running the serial demo.
