Sending Username and Password with TC45

Hi!

I am currently programming a Siemens TC45 using the integrated Java environment (J2ME).

The APN I am connecting to requires the IPCP fields password and username to be filled in (the GGSN is rejecting any pdp-context request without these fields set).

As I want to use more than one simultaneously pdp-context I can not only use the at^sjnet command to specify the APN, username and password.

Consequently, I was hoping that the

at+cgdcont=1,"ip","myapn"
at+cgdata="ppp",1

would provide me with the possibility to negotiate PPP between the Java code and the TC45 GSM stack.

When I issue the at+cgdata command from the Java program it hangs until the command returns

CONNECT

#À!}!}#} }9}"}&} }*} } }'}"}(}"}%}&aóEo}#}%Â#}%Å~
NO CARRIER

Could anyone please help me to establish a pdp-context using the at+cgdata from the Java code on the TC45?

According to Siemens the only GPRS connection that is supported from Java is using the AT^sjnet command.

So, when using J2ME on the TC45 you can only utilise one of the three PDP-contexts the terminal supports. (Of course you may use the other pdp-contexts by using an external entity connecting via the RS232 port, but then the whole point about embedded Java seems to be gone ;-)

What a pitty.

http://www.tdc.co.uk/gprs/tc45.htm has a program : externalcommands.jar which provides a modified dial command which may well do what you want.
