The S120 softdevice, which is a Central capable of 8 concurrent links, plus scanning, is now available for everyone with an nRF51822 kit of some kind, on the download tab of this page: https://www.nordicsemi.com/eng/Products/Bluetooth-R-low-energy/nRF51822/(language)/eng-GB

are you going to implement the Central softdevice? i am having some doubts about the S20 softdevice, by using this one can we able to connect to the multiple slaves at a time?

When receiving advertisements, there isn't any limitation in the specification as such on how many devices you can receive advertisements from.

At some point in time, the advertising devices will however consume all the time on-air, meaning that there will not be room for any more advertisements packets, but the number of devices triggering this will be extremely dependent on advertising intervals and amount of data in the packets. In general, the number of devices will however be very high.

For completeness, the specification limits a Peripheral device to be connected to only one Central at a time. It does however not set any limits for the number of devices you can be connected to as a Central, but this will most often be limited by the implementation. Currently, we don't have any Central softdevice.
