The max number of BLE links is stated in the SoftDevice specification.

yes exactly. There is a Wiznet W5500 + nRF52832 based BLE gateway with wired Ethernet and Wifi project posted which is what I am trying to understand how capable this is in terms of how many BLE nodes it can handle and how quickly data can be stored and/or pushed up to some cloud-based network server.

You mean This: https://www.wiznet.io/product-item/w5500/

So, in either case, all the "backhaul" protocol is handled externally from the nRF chip.

Then the nRF has little to do other than the BLE stuff - so shouldn't be a problem ... ?

Rigado uses an NXP iMX6 A7 with MTG based by module so not quite what I am looking to do.i want to use the 52840 M4 with either a cell back haul or wired 10/100 Ethernet via SPI to Ethernet controller chip such as wiznet w5500.

Yes, this should be doable. Rigado uses Nordic chips in it's gateways (see link).

It may be what you want to do - but it isn't inherent in the words themselves.

We are not mind readers - that's why you need to explain what you're thinking of!

Should be doable.

But not a beginner's project.

Use the nrf52840 as a BLE gateway which means wirelessly connect BLE sensor nodes to the Ethernet (IP) either with cellular, WiFi, of wired Ethernet backhaul. I would like to connect up to 20 BLE beacon endpoint nodes.

Use it for what?

Again, that depends upon your requirements!
