i was setting up a gprs connection with sim300 with vodafone india. The AT commands were. AT OK AT+CIPCSGP=1,"portalnmms" OK AT+CLPORT="TCP","9401" OK AT+CIPSRIP=1 OK AT+CSTT="portalnmms"," "," " OK AT+CIICR ERROR
after AT+CIICR it pauses for a moment and then ERROR occurs. wat might be the problem
after that even if i try executing the command AT+CSTT="portalnmms"," "," " then too it gives an error
This has absolutely nothing whatsoever to do with Keil or C51!
Questions specifically about SIMCOM products must be directed to SIMCOM, or your local SIMCOM Distributor.
but cant u answer or what
No - these are proprietary commands specific to SIMCOM.
