S113 SoftDevice

Memory-optimized Peripheral-only Bluetooth Low Energy protocol stack

The SoftDevices and associated nRF5 SDK are in maintenance mode, see nRF Connect SDK and nRF5 SDK statement for more info. For new projects, we recommend the nRF Connect SDK using either Zephyr RTOS or Bare Metal (for nRF54L Series).

SoftDevice S113 is a memory-optimized Bluetooth® Low Energy protocol stack for the nRF52805, nRF52810, nRF52811, nRF52820, nRF52832, nRF52833 and nRF52840 System-on-Chips (SoCs). Up to 4 connections as a Peripheral can be run concurrently with a Broadcaster. It is Bluetooth 5.1 qualified and supports the following Bluetooth features: high-throughput 2 Mbps and channel selection algorithm 2 (CSA #2). The number of connections and bandwidth per connection are configurable, offering memory and performance optimization.

It is a complete stack with GAP, GATT, ATT, SM and Link Layer. Both GATT Server and Client are supported. The broad feature set also includes Privacy 1.2, LE Data Packet Length Extension, L2CAP connection-oriented channels, configurable ATT MTU and LE Secure Connections.
