Using BLE for Data Streaming

[kapilv]

Does there exist any commercial device in market that uses BLE for data streaming? Is it feasible? Are there any API's to develop such a product?

Actually I just wanted to observe the data packet transmission through a sniffer. But I cannot find commercial devices which use BLE for data streaming. I have a Fitbit but the data transfer is quite small and its not streaming data continously. I want some device like wireless mouse or audio earphone that can stream data over BLE over longer periods of time. Are there any such commercial devices available.

Sorry for the confusion. By "any device" I meant atleast one device. It should be streaming BLE data to some device which is able to recover the data and display it somehow(better if the data is audio).

I would like to stream data between two devices then cut-off the power to one device and see how the other one reacts by observing its packet on a packet sniffer. If the devices are commercially available that would be great.
