Packet sniffer with USB Dongle hanging issue

Hi all,

for long time I am using packet sniffer with cc2540 USB dongle 

but most of the times whenever I try to connect to slave device from master

my packet sniffer gets hang and it occurs most of the time.

I think the issue is with cc2540 dongle firmware which fails most of the time

when most of the packets being exchanged between master and slave

and during connection establishment between the two

TI kindly suggest solution for the same

Regards,
