Maybe you haven't (quite) got the UUID right somewhere?

What is the Central actually seeing?

What happens if you just use a basic Central with no filtering ... ?

The whole point of standards like Bluetooth is that this stuff does not depend on particular devices.

The nRF52840 as Central just sees Bluetooth packets; it neither knows nor cares whether they come from a phone or a PC or another nRF chip - The behaviour is identical, as specified in the BLE standards.

Again, that has nothing to do with Nordic.

You will have to study the developer documentation for whatever mobile OS(es) you're using - Android, iOS, or whatever.

eg,

https://developer.android.com/guide/topics/connectivity/bluetooth-le

https://developer.apple.com/bluetooth/

You will need to go to a mobile OS developer forum for mobile OS development support.

It depends on the phone - not all phones have the capability.

It probably also depends on the version of the phone's OS.

On Android (I know nothing about iOS), nRF Connect can act as a peripheral - if the phone supports it.

As Andy says, this has nothing to do with Nordic - you need the developer support resources for the mobile OS in question...

The softdevice supports up to 20 peripheral/central links simultaneously.

so that i can connect more mobile to one central instead of more number of boards

You will probably get more help in iOS or Android forums, as your question isn't really about Nordic products or Bluetooth in general.

But anyway, I would like to know why you would want to do that? (phone as peripheral)
