Maximum devices count in BLE

[Fabien Comte]

Hello,

I have a request for a system (powered with a nRF52840) that should manages up to 60 devices.

Is that possible ?

What kind of settings can I expect (connection interval, …) ?

Thank you

Ok I understand, thank you for the answers.

Mesh is not possible in my case because it's a soft real time system (should react in 500 ms 95 % of the time) with batteries so a connection with a timeslot is much more efficient compared to advertising. And connected way use a radio frequency hopping pattern and minimise collisions that interest me for industrial environnements.

"Also, as you say you're managing both ends of the link, does it have to be BLE ... ?"

This is a good point. If you do something proprietary you can establish a link to 60 nodes or more, but you would have to implement something similar to the Bluetooth link layer on your own, which means the software development effort would be much higher (not to mention the testing requirements...).
