GPRS Shield Start Issue.

Dear all,

  1. The GPRS Shield default baud rate setting is auto adaptive. You need to set the baud rate at the first time when you began to use this GPRS shield. You can do this by Programming or Serial tool.

More step please go to view the WIKI :

  1. Another problem is the Arduino UNO USB socket is to high and it is make from metal. So when plug with GPRS Shield the Shield bottom welding point could be short. That affect GPRS module and some time might be burn the Shield.

Before work with Uno, please stick some taps or insulation on the USB socket.

For now we would change the pins longer in next version.

Ok so this could be the cause for some boards being shorted because the UART pins are shorted by the USB ?
