I am using two Sim 300 MODEMs for server client application.I am able to communicate in non-transparent mode, but i can not communicate in transparent mode.
My Client Code
Code:
>>AT+CIPMODE=1
<<OK
>>AT+CGATT=1
<<OK
>>AT+CSTT="www"
<<OK
>>AT+CGDCONT=1,"IP","www"
<<OK
>>AT+CDNSORIP=0
<<OK
>>AT+CIICR
<<OK
>>AT+CIFSR
<<XXX.XXX.XXX.XXX // OWN IP ADDRESS
>>AT+CIPSTART="TCP","<IP OF SERVER >","<PORT>"
<<CONNECT
// FROM HERE MODEM IS STAYING IN DATA MODE
My SERVER CODE :
Code:
>>AT+CIPMODE=1
<<OK
>>AT+CGATT=1
<<OK
>>AT+CIPCSGP=1,"www"
<<AT+CLPORT="TCP","XXXX"
>>AT+CIPSERVER
<<OK
<<SERVER OK
>>AT+CIFSR
<<xxx.xxx.xxx.xxx // MY SERVER IP
<<REMOTE IP: XXX.XXX.XXX.XXX
>>AT+CIPCCON=2
<<OK
>>AT+CIPSEND
<<ERROR
>>AT+CIPSERVER?
<<+CIPSERVER: 1
>>AT+CIPSTATUS
<<+CIPSTATUS : IP STATUS
above code in none transparent mode(with AT+CIPMODE=0) works fine.
