Throughput over mesh is significantly lower compared to normal BLE connections, that is correct. If you only have 3 devices in your network I don't think mesh is the best option.

I mean those devices are going to communicate frequently and the data packet is big. Isn't that the mesh communicates relying on advertisement and thus the data throughput is quite small?

In what way(s) do you think a Mesh is not "active" ?

Thank you very much.

The devices would communicate actively and thus I think mesh can't manage it.

Does it have to be specifically Bluetooth?

Have you considered Mesh?

Hi Duncan

You can do this with the S132, yes, as it supports both peripheral and central links running concurrently.

The easiest way would be to make one device connect to the other two devices as a central, one device needs to connect to the other two devices as a peripheral, and the last device needs to connect to one device as peripheral and one as central.

Then they should all have a connection with each of the other two devices.

We don't really have any examples for this use case, but the ble_app_hrs_rscs_relay example might be a good place to start.
This example sets up 2 central links and one peripheral link on a single nRF52 device, making it somewhat similar to your use case.

Best regards
