Memory-optimized Peripheral-only Bluetooth Low Energy protocol stack
The S113 SoftDevice is a Bluetooth® Low Energy peripheral protocol stack solution. It supports up to four peripheral connections with an additional broadcaster role running concurrently. The S113 SoftDevice integrates a Bluetooth Low Energy Controller and Host, and provides a full and flexible API for building Bluetooth Low Energy Nordic nRF52 System on Chip solutions.
SoftDevice S113 is a memory-optimized Bluetooth® Low Energy protocol stack for the Nordic nRF52805, nRF52810, nRF52811, nRF52820, nRF52832, nRF52833 and nRF52840 System-on-Chips (SoCs). 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.
