How to interface SIM39EA gps module

Hey Friends!
I need some help in interfacing SIM39EA module. I look for the datasheet, but nothing specified for program interface commands. I know its using UART interface but we must write some commands in the return of that it will return us some values.
So can anyone help with this.

You need to use these commands
This is the command set which should help, as SIM39EA is MTK3339 chipset inside.

Can you provide the example of the sample code so that it will much help full?

I don’t have example code. You should just print the commands on UART.
