 Hi All,

I am doing file transfer using blueooth. During file transfer some
times the transfer progress bar on GUI stops on both side(sending and
receiving side) and stays forever in that state.

I tried to get logs from hcidump, there it displays traffic while
transferring but after that progress bar stops hcidump stops
displaying traffic.!

can I get any clue for this behavior and at what layer I need to
debug.

Thanks
