Hi everybody,

I´m trying to make GPRS/IP (General Packet Radio Service/Internet Protocol) connection with a Wavecom Fastrack Supreme Modem.

I search the Network parameters for GPRS connections of my mobile operator.
http://ewon.be/Download/TN/GPRS%20network%20param.pdf

In HyperTerminal (115200-8-N1), I sent the following AT commands, and i got these responses:

AT+CGDCONT=1,"IP","internet"
OK
ATD*99***1#
CONNECT 115200
~ }#À!}!}!} }6}!}$}%Ü}"}&} } } } }'}"}(}"}#}$À#&´~~ }#À!}!}!} }6}!}$}%Ü}"}&} } }
 } }'}"}(}"}#}$À#&´~~ }#À!}!}!} }6}!}$}%Ü}"}&} } } } }'}"}(}"}#}$À#&´~~ }#À!}!}!
} }6}!}$}%Ü}"}&} } } } }'}"}(}"}#}$À#&´~~ }#À!}!}!} }6}!}$}%Ü}"}&} } } } }'}"}(}
"}#}$À#&´~~ }#À!}!}!} }6}!}$}%Ü}"}&} } } } }'}"}(}"}#}$À#&´~~ }#À!}!}!} }6}!}$}%
Ü}"}&} } } } }'}"}(}"}#}$À#&´~~ }#À!}!}!} }6}!}$}%Ü}"}&} } } } }'}"}(}"}#}$À#&´~
~ }#À!}!}!} }6}!}$}%Ü}"}&} } } } }'}"}(}"}#}$À#&´~~ }#À!}!}!} }6}!}$}%Ü}"}&} } }
 } }'}"}(}"}#}$À#&´~
NO CARRIER

I search in forums, and I read that the garbage sent to the terminal and the "NO CARRIER" response, due "ATD*99***1#", happened because the PPP (Point-to-Point Protocol) authentication failed.

I know the usernamer and password, but i don´t know how to associate them to the APN (Access Point Network). I think that´s the way to solve the problem.

Please help me...

Thanks in advance.

your connection is working 100%.. but you are not running a PPP Connection.

Set up the connection as a dialup connection with the correct init string and it will work. not via hyperterm


Thanks

Create a dialup connection. Use *99# number to dial and enter the CGDCONT string in the modem initialisation settings. Then just "dial"...

My gold was to establish the GPRS/IP connection only with AT Comands, without dial-up-connection windows application help.

There?s a wavecom plug-in to Open AT Suite called WIPsoft which permits to create a GPRS connection, and to create TCP socket, only using AT Commands.

I hope this help wannabe geeks like me. See ya.

Here is the general sequence I use on my 8051's to get the Wipsoft stack to establish a TCP connection. At one point before all this I assume you have issued AT+WOPEN=1 to start ATOPEN this only ever needs to be issued once unless a firmware upgrade has been performed.


AT+WIPCFG=1 /to start IP Stack
AT+WIPBR=1,6 /to open GPRS bearer
AT+WIPBR=2,6,11,"internet" /to set APN of gprs
AT+WIPBR=4,6,0 /to start bearer
AT+WIPCREATE=2,1,"XXX.XXX.XXX.XXX",YYY /create client socket index=1, on server IP XXX port YYY
AT+WIPDATA=2,1,1 /exchange data on socket index 1



And to close issue standard +++ and wait 1sec for AT response


AT+WIPCLOSE=2,1 /close TCP client socket index1

Cheers


Cyril
