Hi again

I would recommend you to check out this blogpost we made about LE Audio a while back

Hi Urvisha

I'm just checking in with the one of the audio expert regarding your question. Could you elabroata a bit more regarding the requirement to bitrate/quality?

Hello,

Thank you for your quick support.

[quote userid="122502" url="~/f/nordic-q-a/103140/is-it-possible-to-transfer-audio-signal-on-ble-using-nrf52/443306"]If you are interested in audio you should instead look at:

Using the nRF5340 can I achieved my application goal to transfer/ received live audio signal?

As I mention earlier in my application we require half duplex communication means at a time device in receive mode or in transmit mode.

Please give your suggestion as soon as possible.

Thank & Regards,

Urvisha Andani

Hi,

It's possible, but I don't recommend it. The latency would be quite high, so depended on the use case it might not be a good idea. to quote a collauge in a similar case

Hello,

We have done some attempts in the past, for instance to transmit audio commands from a nRF52 to a peer device. These were short audio commands that could go into a search field of for instance google.com. This was done on a thingy 52:

Have in mind though this was many years ago, and the tools used are outdated, though you may still find some of it useful if you want to take a look at it.

Have in mind two things: The latency will be very high, so there is no chance of any real-time streaming. This also means that you only can transmit short audio snippets, not continouse audio this way.

Sure, Actually in my project i want to transfer the live audio signal over BLE using nrf52832/nrf5240.

So my question is is it possible or not? If yes then can you please provide some example of it?

Is the plan to use BLE Audio or audio over BLE?

I am planing to send/recive the live audio signal over BLE.

As for the sdk I recommend nRF Connect SDK

We also have the nRF5340 Audio https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/introduction.html

Is the plan to use BLE Audio or audio over BLE?
