Alternative to BLE Mesh - a star topology?

Hi,

With the S140 SoftDevice running on the nRF52840 you are able to run 20 concurrent BLE connections. That means that the nRF52840 can have e.g. 10 peripherals connections and 10 central connections at the same time, or 1 central connection and 19 peripherals connections. It's not a proprietary protocol, it's still BLE. How the decives should connect to each other is up to you, so you can configure the topology as you want. We have a Youtube video illustrating this here.

Was the person actually referring to an existing product, or just suggesting that you develop something proprietary yourself?

Does it have to be BLE?

nRF52840 also supports IEEE 802.15.4 - there are many things based on that ...

Or you can go entirely proprietary ...

There's also https://github.com/NordicPlayground/nRF51-ble-bcast-mesh - which, I think, was a proprietary BLE mesh before the SIG released its formal BLE Mesh standard.
