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.

What do you mean by "data"? what kind of data do you want to stream? Should the device stream the data to a computer or a phone, or another kind of device? Also what speed/throughput do you need?

No I just want to observe the data packet transmission on a sniffer. So, I don't exactly care what data it is. I want a commercial device which will streams data to any device it wants. I also don't care about the speed as long as it transfers data for a long time.

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.

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.
