Hello, i bought the 3G/GPRS shield for Arduino and I’m trying the HTTP tutorial from your site, but it’s not working! Any suggestions? and how to know that it's working correctly or not?

The tutorial:
https://www.cooking-hacks.com/documenta ... al/#step15

The following output appears on the serial monitor:

Starting...

AT+CPIN=0000
AT+CREG?
AT+CGSOCKCONT=1,"IP","zain"
AT+CSOCKAUTH=1,1,"zain","zain"

PS: the module worked correctly for the SMS tutorial.
Thanks in advance.

Hi,

Did you set the correct apn? Is the pin of the sim card enable? Did you set the pin if it is enabled? If it is disabled please comment out the line that send the at+cpin command?

What does the module return to at+creg? and at+cgreg?

Regards

i did all what you have mentioned and still not working.
can you provide me with serial monitor correct output so i can compare it with mine?

Hi,

Could you please send manual at commands to the module? What does the module return to at+creg and at+cgreg commands?

Regards
