How many devices are supported in a Bluetooth mesh by nRF52840 and nRF52833?

Hi,

How many devices can be meshed in Bluetooth? I see that both NRF52840 and NRF52833 support Bluetooth 5.3. As I know normally v5.3 supports up to 7 devices. Is it same for NRF52840/NRF52833 or less?

We want to mesh 4 devices as a standard + 2 devices optional in an audio project. All devices will talk to each other. We are goingto develop an intercom system from scratch.

Sorry I couldn't find the edit button of my last comment. There is no handle button. Let me explain the project. I would like to share it as a private but it is easier to explain. It is already a signed project so no matter to share generic info.

People who do extreme sports have their own headset. When a group of people comes together (as a team or a support unit) in an event they will pair their devices among the group. Group members can be change in any event.

The topology is that the team leader can hear all and cross talk with others, however other members can hear and talk only with the leader.

If that topology is impossible, then we can think that everyone in the group can hear and talk each other at same time.

There won't be a push button to talk in both topology.
