5

How many devices can we connect to the Bluetooth 5 and can get info about the total no. of Bluetooth within that signal?

Which devices can help to do it.

For classic Bluetooth the limitation is 7 connections and this has been the case since before Bluetooth 5 was released. For Bluetooth Low Energy (BLE), there is no limitation on the number of connections, and that is purely dependant on the hardware's/stack's capabilities. The Bluetooth specification does not put a limit on the number of connections for BLE, and therefore the theoretical maximum depends on Bluetooth-related timings (namely connection interval and connection supervision timeout).

For a more detailed answer about the number of connections. please see the link below:- https://stackoverflow.com/a/39174115/2215147

I hope this helps.

    Where did you get 2 billion connections from? That's impossible since they all need one connection event at least every 32 seconds. But you can't fit those many packets in the air during that time. – Emil Jan 25 '18 at 13:20

    I've misplaced the 2 billion connections comment, that should've been before the Bluetooth-related timings restriction. 2 billion comes from the fact that a BLE packet's Access Address is 32 bits, therefore 2^31 = ~2billion, but you're right, this is not possible because of the connection supervision timeout. I have modified my comment to reflect that. – Youssif Saeed Jan 30 '18 at 10:11
