Hi Siddhant,

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.
