Engineering build of S120 and an updated nRF51 SDK will available as a download for existing customers of nRF51822.
   
The S120 is an 8-link central role Bluetooth low energy SoftDevice for the nRF51822 SoC. The solution includes all Bluetooth low energy protocol layers up to and including GATT/GAP.  The S120 supports multi-link central and observer roles, GATT server and client, and event driven, asynchronous and thread safe GATT/GAP and L2CAP APIs. S120 offers the capability to support eight simultaneous links for Bluetooth low energy hubs that are not smartphones or tablets.   
   
S120 is complemented by the nRF51 Wireless Charging SDK and includes services/profiles for a Rezence Power Transmitting Unit (PTU), Power Receiving Unit (PRU) and state machine examples.

The solution offers a wide range of Bluetooth low energy services/profile plus complete examples to simplify and speed up application development. The current nRF51 SDK takes advantage of the nRF51 series flash-based architecture and offers developers a wide range of features and examples such as Over-the-Air Device Firmware Upgrade (OTA DFU). S120 together with the nRF51 Wireless Charging SDK provides a solution for the Out-of-Band (OOB) signaling part of a Rezence charge pad. With the support for 8-link concurrent link, a charge pad based on nRF51822 can support simultaneous charging of up to eight devices.   
   
Rezence, which was developed by the Alliance for Wireless Power (A4WP), is a wireless power transfer technology and specification based on the principles of magnetic resonance. The technology can turn almost any surface into a wireless charging surface capable of powering any Rezence enabled mobile device.
