Hi,

 

I'm trying to establish a GPRS connection with Siemens MC35 GSM modem, sometimes it's connecting successfully, sometimes not. On my host computer it's always working successfully.

ATefining PDP context...n connection at any stage!

OK

ATH

OK

ATE1

OK

AT+CGDCONT=1,"IP","internet.mts.ru"

OKnwaiting for connect...n

ATD*99***1#

try restarting the phone.ntiations fail,n

Serial connection established.

using channel 1

 

Using interface ppp0

Connect: ppp0 <--> /dev/ttyBF0

 

sent [LCP ConfReq id=0x1 <asyncmap 0xa0000> <magic 0x9ef83ea3>]

sent [LCP ConfReq id=0x1 <asyncmap 0xa0000> <magic 0x9ef83ea3>]

...

 

I'm using 2008R1 on BF537 STAMP.

 

Thanks in advance.

I've just found out that dialing a number on the stamp and on my host isn't equal in its result.

 

tip -c -r -s57600 -l/dev/ttyS0

atd*99***1#

CONNECT

~?}#?!}!}#} }9}"}&} }*} } }'}"}(}"}%}&?;}1}8}#}%?#}%({~~?}#?!}!}#} }9}"}&} }*} }...

 

 

 

On the stamp "CONNECT" is the last thing, there is no tilde and others.

 

Serial driver problem?

Slava:

 

Do you have an exact part number were we can get the same serial device you are connecting to so we can try it out?

 

Thanks
