S120 SoftDevice

The S120 SoftDevice is a Bluetooth® Low Energy (BLE) combined central and peripheral protocol stack solution, which means that the SoftDevice can be initialized to run either as a central protocol stack or as a peripheral protocol stack. When initialized as a Central, it supports up to eight simultaneous central role connections and an Observer. When initialized as a Peripheral, is supports a peripheral connection and a concurrent Broadcaster. The SoftDevice integrates a low energy controller and host, and provides a full and flexible Application Programming Interface (API) for building Bluetooth Low Energy System on Chip (SoC) solutions.
