Multiple BLE Audio Source Devices Outputting to a BLE Audio Sink Device

[John]

Hello,

I am exploring different Bluetooth LE audio options and I have a question about capabilities.

• Is it possible to connect to multiple Bluetooth LE audio source devices (microphones) to 1 central device?
• Can the central output all of the audio source streams to a singular Bluetooth LE audio sink device?

I don't know if syncing all of the devices will be an issue.

Hi

Unfortunately it is still a bit early days for LE Audio. The full profile specification is not yet released by the Bluetooth SIG, and as such we don't have support for it in our Bluetooth stacks or examples.

Is it possible to connect to multiple Bluetooth LE audio source devices (microphones) to 1 central device?

Theoretically this is possible, but it is not a primary use case for LE Audio.
The problem of this use case is that the different audio sources will not be synchronized, so you might have timing conflicts between them on the central device leading to packet loss. 

Can the central output all of the audio source streams to a singular Bluetooth LE audio sink device?

This is possible, yes. 

Please note that I am just talking about what the specification allows, since we don't yet have an implementation.

Best regards

Do you have a timeline when Nordic will be supporting LE Audio and when there would be a dev kit available?

Hi 

We don't have a set release date for this yet, but it should be ready some time next year. 

If LE Audio is important to you I suggest you discuss this with one of our sales representatives. If you don't have any sales contacts in Nordic just let me know, and I will put you in touch with one of our regional sales managers. 

Best regards
Torbjørn
