The GPRS shield can't work without an Arduino

Hi friend:
1.You can put the jumper cap plug in the USB interface
2.If prompted to install the driver is good,but need to replace the FT232

HI friend:
You can enter the serial monitor, and then change the baud rate is 115200

According to the figure, weld the plate connected, and then download code from the official website .
