Hey guys, your are my last hope. 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? i think I'm going mad about all this stuff.... Please help me....
