Hi!!
I have a problem with your GPRS SHIELD.
I try to do an HTTP request like this
AT+CSQ
AT+CGATT?
AT+SAPBR=3,1,"CONTYPE","GPRS"
AT+SAPBR=3,1,"APN","mobile.vodafone.it"
AT+SAPBR=1,1
AT+HTTPINIT
AT+HTTPPARA="URL","nic.ing.unimo.it/arduino/"
AT+HTTPACTION=0
AT+HTTPREAD
This instructions work perfectly but only one time… If I want to do another HTTP request like this I have to switch off the shield and, after turn on, do the same instructions another time. I have the same problem when i load on arduino this sketch (with the same parameters of the AT commands upside), that is present in the page about gprs shield, and i try to do more than one HTTP request…
seeedstudio.com/wiki/GPRS_Sh … e_Examples
The return of the HTTP request is often 408 (request timeout), sometimes nothing…
Can you give me some help?
