Hi i am using wavecom modem fatrack SUPREME. I trying to commnuicate between client and server through GPRS. But it’s giving some problem.
I am using this commands.
AT+WIPCFG=1
OK
AT+WIPBR=1,6
OK
AT+WIPBR=2,6,11,“AIRTELGPRS.COM”
OK
AT+WIPBR=4,6,0
OK
AT+WIPCREAT=2,1,“192.168.1.72”,5001

After that simply it’s waitting.
I am not able to communicate with server.
Can u tell me what’s the problem.

AT+WIPCREAT=2,1,“192.168”,5001

Shouldn’t that “192.168” be a complete IP address?

Note also that any IP address beginning “192.168.” is private - it will not be contactable via GPRS or any other external device!

See:
wavecom.com/modules/movie/sc … ht=192+168
wavecom.com/modules/movie/sc … ht=192+168

“Private IP Addresses” - See:

en.wikipedia.org/wiki/Private_network

RFC1918, Address Allocation for Private Internets
tools.ietf.org/html/rfc1918

@RFC1918

The Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of the IP address space for private internets:

10.0.0.0        -   10.255.255.255  (10/8 prefix)
     172.16.0.0      -   172.31.255.255  (172.16/12 prefix)
     192.168.0.0     -   192.168.255.255 (192.168/16 prefix)

We will refer to the first block as “24-bit block”, the second as “20-bit block”, and to the third as “16-bit” block.
