I think there are some problem in releasing device. Generally Bad File Descriptor comes if socket does not get closed properly. Actually rfcomm takes some time to set free device. try to put some sleep time in between release and again bind. Even binding at hci layer is longer then rfcomm layer. But can u tell me how did u send file to your handset. or ur testing it with pc to pc. hcidump will also be useful.

ur code seems to be fine. I think there are some problem in releasing device. Generally Bad File Descriptor comes if socket does not get closed properly. Actually rfcomm takes some time to set free device. try to put some sleep time in between release and again bind. Even binding at hci layer is longer then rfcomm layer. But can u tell me how did u send file to your handset. or ur testing it with pc to pc.

hcidump will also be useful.

hi vikas ,
            Really great to get i reply from you. I was trying to write a program that can send file to my nokia phone. I was looking for a api that can create a character device which can be passed to ioctl. To do so what i am doing right now is

i)              char cmdBuf[256];
                sprintf(cmdBuf,"mknod %s c 216 %d",tempBuf,dev);
                if (system(cmdBuf) != 0 )
                {
                    fprintf(stderr,"\nError in executng mknod\n");
                    exit(1);
                }

ii) And then
err = ioctl(ctl, RFCOMMCREATEDEV, &req);

iii) For releasing the device i am doing :-
err = ioctl(ctl, RFCOMMRELEASEDEV, &req);

These things are working fine for a single run but after 2 run (keeping the above 3 in while(1) block) ; while releasing the device , ioctl gives error bad file descriptor. Please tell me what i am doing wrong.

regards
siddhant
