Hey guys,

I'm doing a practicum. I

I have to develope a way to read SMS from a Nokia cell phone (3109c) by
a computer.

I did some researches and figured out, reading the SMS by AT commands is
possible for cell phones with s40.

Therefor i started to search for an alternate way for reading the SMS.
The i came across FBUS&OBEX

I catch up on the needed frames of OBEX&FBUS to read SMS from the cell
phone an finally thought i have everything, what is needed for this
possbility.

But then i recogniced, that there is still a problem how to connect the
cell phone with the pc.

I tried to sent the Hexdata to the phone by hyperterminaln or by a
SerialPortmonitor.
To initialize the FBUS mode over bluetooth, you have to sent 'U' in
Hexformat (0x55), I think 128 times.

But I didn't get any reaction by the cellphone. While sending the Us to
the cell phone i monitored the used Comport.

Neither of them reacted in the wished way.
One of them just echoed, what i sent, the other didn't anserw anyway...

Why the h*** am I not possible to sent the hex datas to the cell phone?
Is there a speacial bluetooth protokoll or comport, which I have to use?
If yes, how can it be used or opened?

Please help me....
