So, I needed GPRS on my application and I bought a GPRS shield V2.0.
I’m using a FTDI enabled board (sparlfun XBee Explorer), I have the jumper on the correct position, in order to select the hardware serial. I power the board from the 5V output from the XBee exporer board, the leds light up, I press the power button for a couple os seconds, everything seems to be ok, since I called the SIM I inderted on the module and I don’t get the unconnected message from the network. So, I connected the Tx/Rx pins from the shield to the Tx/Rx pins (Di/Do) on the xbee explorer. Nothing happens. I can’t see nothing on the terminal, try to enter At commands, nothing. I tried all available baud rates. The xbee explorer is fully functional with any other serial devices and I also have a different model that I tried and nothing.
I also have i my posession a 1.0 version of the shield, same behavior. I tried powering woth an external ac adapter, same behavior.
Thanks in advance.
