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.

well there isn't a device which streams data to 'any device it wants' because most devices need data in a particular format or at particular times depending on the profiles and services they support.

Nothing stops you using two nordic kits to write such a thing. Make your own service which has one characteristic, doesn't matter what, write a central which connects to it and sets up notifications, then have the peripheral update that characteristic via notification constantly. You now have a stream of data.

Not quite sure what you're hoping to see on the sniffer in that case, but that would be a stream of data.
