S120 nRF51 SoftDevice Specification v2.1
Introduction
1
The S120 SoftDevice is a Bluetooth® low energy (BLE) combined Central and Peripheral protocol stack
solution. That is, 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.
This document contains information about the S120 SoftDevice memory and resource requirements. It also
describes the performance and BLE features of the SoftDevice when configured as a Central. For BLE
features and functionality when configured as a Peripheral, see the S110 SoftDevice Specification.
Note: The SoftDevice features and performance are subject to change between revisions of this
document. See Section 15.2 “Notification of SoftDevice revision updates” on page 53 for more
information. This specification outlines the supported features of a production level
SoftDevice. Alpha and beta versions of the SoftDevice may not support all features. To find
information on any limitations or omissions, see the SoftDevice release notes, which will
contain a detailed summary of the release status.

Product overview

This section provides an overview of the SoftDevice.
SoftDevice
2.1
The SoftDevice is a precompiled and linked binary software implementing a Bluetooth 4.1 low energy
protocol stack for the nRF51 series of chips. See the nRF51 Series Compatibility Matrix for SoftDevice/chip
compatibility information.
The Application Programming Interface (API) is a standard C language set of functions and data types that
give the application complete compiler and linker independence from the SoftDevice implementation.
The SoftDevice enables the application programmer to develop their code as a standard ARM® Cortex™-M0
project without needing to integrate with proprietary chip-vendor software frameworks. This means that
any ARM® Cortex™-M0 compatible toolchain can be used to develop Bluetooth low energy applications with
the SoftDevice.

The SoftDevice can be programmed onto compatible nRF51 Series chips during both development and
production.
Multiprotocol support
2.2
The SoftDevice supports both non-concurrent and fully concurrent multiprotocol implementations. For
non-concurrent operation, a proprietary 2.4 GHz protocol can be implemented in the application program
area and can access all hardware resources when the SoftDevice is disabled. For concurrent multiprotocol
operation, with a proprietary protocol running concurrently with the SoftDevice protocol(s), see Chapter 8
“Concurrent Multiprotocol Timeslot API” on page 20.

Bluetooth low energy protocol stack
3
The Bluetooth 4.1 compliant low energy Host and Controller embedded in the SoftDevice are fully qualified
with multi-role support (Central and Observer or Peripheral and Broadcaster). The API is defined above the
Generic Attribute Protocol (GATT), Generic Access Profile (GAP), and Logical Link Control and Adaptation
Protocol (L2CAP). The SoftDevice allows applications to implement standard Bluetooth low energy profiles
as well as proprietary use case implementations.
The nRF51 Software Development Kit (SDK) complements the BLE protocol stack with Service and Profile
implementations. Single-mode System on Chip (SoC) applications are enabled by the full BLE protocol stack
and nRF51 series integrated circuit (IC).
