S312SoftDevice

Bluetooth 5 and ANT protocol stack

SoftDevice S312 is a combined Bluetooth 5 and ANT™ protocol stack for the nRF52810 SoC, supporting concurrent operation of the two.

It is a Bluetooth 5 qualified protocol stack that offers up to four connections as a Peripheral concurrently with a Broadcaster. It supports the following Bluetooth 5 features: 2 Mbps and channel selection algorithm #2 (CSA #2). 2 Mbps gives better throughput and energy efficiency, while CSA #2 provides better coexistence between Bluetooth LE devices. The number of connections and bandwidth per connection is configurable, offering memory and performance optimization.

It is a complete Bluetooth LE 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, configurable ATT MTU and LE Secure Connections.

It supports all ANT features and offers a variety of network topologies, including peer-to-peer, star and tree. Up to 15 individual channels are available, with broadcast, acknowledged, or burst transfer communication.
