S140 SoftDevice

Feature-rich Bluetooth Low Energy protocol stack

SoftDevice S140 is a feature-rich Bluetooth® Low Energy protocol stack for the nRF52811, nRF52820, nRF52833 and nRF52840 System-on-Chips (SoCs). It supports up to 20 concurrent links in all roles (Broadcaster, Central, Observer, Peripheral). It is Bluetooth 5.1 qualified and supports the following Bluetooth features: high-throughput 2 Mbps, Long Range, Advertising Extensions 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, L2CAP, and Link Layer. Both GATT Server and Client are supported. The broad feature set also includes Privacy 1.2, LE Data Packet Length Extension, configurable ATT MTU, L2CAP connection-oriented channels and LE Secure Connections.
