I can write a program to send SMS messages by using Nokia PC Connectivity SDK2 + DLR-3P cable + 6210. It is OK and very stable.
But,when I using the IrDA interface to instead the DLR-3P interface,
My computer can detect the phone and the Nokia Connection Manager also can detect the phone but my program can not send any SMS message and I will receive a error code : 7935 (unknow error).
Can anyone tell me how to solve this problem?
