It is indeed possible to stream mono audio between 2 SOCs (nRF51 or nRF52 SoCs). I prefer the nRF52 series as it has the BTLE 2 Mbps mode which doubles the on air bandwidth, but mono audio works quite well even with BTLE 1 Mbps mode.

We have examples for Mono audio in the Smart Remote 3 reference design. However we do not have examples for stereo audio.

Our customers have however been able to achieve stereo streaming so this is indeed possible and this has been done using the nRF51 series.

One of the key challenges that you need to address will be Left and Right synchronization, which make stereo streaming a bit more complex than mono streaming. Unfortunately we do not have an out of the box solution for this.

If you need more support on your design, you can reach out on our one-on-one support forum called Nordicsemi Mypage.

@sam , I dedicate You this song, please playback it after you finish Your system.

Answering your question - yes, in general it is POSSIBLE. But the quality... it is other question that needs answers you don't want to provide.

If you don't want to answer technical issues fine I have other soc and tech for implementation.

Phrases like "shity answer", "you dumb", "shut your mouth" are not acceptable. Be polite.

I haven't comment anything wrong i mentioned board I mentioned application.so this two things are enough for explanation.

@sam Your behavior is not acceptable. Endnode was just trying to help you, and has actually given you a good answer. If you are not happy with it, you need to provide more information, and answer his questions. I highly recommend that you change your attitude.

For your information nrf51422 using all protocols

And you wanna teaching me protocols for your information I am master in electronics and computer science so please shut your mouth

You need to be much more specific to tell you if some HW supports it. What bandwidth, what range, what reliability you expect, what will be on both sides of the wireless link etc.

And I think your not from technical team so don't give shity answer if you don't know. My question is correct you dumb don't try to be over smart I have ask about hardware support not code so chill

sam — Mon, 17 Apr 2017 21:45:57 GMT

Don't worry about coding just tell me whether hardware support it

Hi Sam,

I'm afraid your description is pretty vague. Note that there is no audio-transfer protocol defined for Bluetooth Low Energy (yet) and so no Nordic chip is meant for such applications. However BLE might achieve (with some assumptions like low-noise environment = good link) bandwidths which might be OK for some Low/Mid res audio application. Then you are giving us a choice between 5-year-old nRF51 chip and not-yet-available nRF52840 ignoring other options like nRF52832. In the end answer will largely depends on how good you are with embedded programming (C) because application you are talking about requires lot of custom code and skills.

Cheers Jan
