Do current BLE modules support v4.1 or 4.2 of Bluetooth?

I'm a new at BLE. So, as I know from bluetooth spec v 4.1 there is a opportunity to establish multiple connections to the same peripheral device from several central devices. Does any Nordic BLE module support this functionality? What vendors does this function support?

Hi

Nordic's latest BLE protocol stacks (the SoftDevices) support BLE V4.2. The SoftDevice S132 is for nRF52 and the S130 is for nRF51. If you have a look at the Multilink scheduling chapters you will find that the S13x SoftDevices supports

"...up to three connections as a central, up to one connection as a peripheral, an advertiser or broadcaster and an Observer or Scanner simultaneously."

Thanks for your answer! But one thing is not so clear.

"...up to three connections as a central, up to one connection as a peripheral, an advertiser or broadcaster and an Observer or Scanner simultaneously."

But what if I want to have only 3 peripheral connection simultaneously and no one from others types. Is it possible? I mean can I connect to one peripheral device from several central devices? To correspond to this condition

• A peripheral can be connected to multiple centrals.

Edit: Pål has a better answer.

It's ok but nevertheless there is described that multiple peripheral connections are possible. So, it's possible and it works but there are different networks. Is it right?
