I bought a GPRS sheild for arduino Uno from seeedstudio (http://www.seeedstudio.com/wiki/index.php?title=GPRS_Shield_v0.9b) and did everything as mentioned in the wiki page. however when i connect the GPRS rx and tx pins to arduino uno pins 7,8 and use the newsoftserial as mentioned, i don't get any response to the AT commands in my terminal program. however if I directly connect these rx,tx pins to hardware rx,tx pins (0,1) on arduino (i.e. hardware urt as mentioned in wiki page link above) i'm able to send SMS messages and the Gprs unit responds to all commands. so the GPRS unit as such is functionning properly but having problems with the newsoftserial connection. Could somebody help me on how to get it working. i have played with different baud rates (4800,9600,19200) but of no use. unfortunately seeedstudio forums are not very helpful on this issue.
