Audio Streaming on nRF52

[JakeSprenger]

Hi,

The project I am working on involves streaming 8 audio streams (16 channels of data), and I was hoping to use the nRF52 for this purpose. Does anyone have any ideas on the best way to implement this? I recognize that BLE is not the best for this application, however, I see that other audio-streaming applications have been done with this board. 

So, my question is: what is the best way to stream large amounts of data in real time, using an nRF52?

Thanks in advance for the advice.

What kind of audio - mono/stereo? sample rate? sample size?

I intend to be using Stereo audio. I've checked the other forum threads, yet none of them had suggestions for the best way to implement this.

You may or may not have heard that Bluetooth is in the making of BLE audio, but at this point this is not available. The specification is not finished.

Until then, if you want to transfer audio over BLE, I guess it is a matter of throughput. The maximum throughput is 1.3MBPS (bit not bytes) payload divided between all BLE links. Then you have latency vs throughput, and the fact that it is not possible to discard packets, so if a packet is lost, it will be retransmitted.

BR,
