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.

Hi Abhijith,

In fact we want to develop a custom walkie-talkie. Only our brand devices can be matched up to 6 devices. No phone or other 3rd party devices will join the network. The topology can be like 1 master + 5 slave (bi-directional audio). I guess BLE is much more efficient such kind of application.

Another question is whether nRF5340 has a significant advantage compared to nrf52840? There is also an ongoing project with NRF52840. If there isn't a big difference then we want to go with nrf52840 to reduce complexity.
