S112 SoftDevice

Memory-optimized Bluetooth 5 protocol stack with dual peripheral and broadcaster roles

Nordic Semiconductor’s S112 v5.1 is a memory-optimized Bluetooth® 5 protocol stack for building high-performance Bluetooth Low Energy applications on the nRF52810 multi-protocol SoC. S112 occupies approx. 100kB of flash memory and thus enables more sophisticated applications that require fewer connections when in operation. S112 supports the following Bluetooth LE roles in concurrent operation:

  • Peripheral x 2
  • Broadcaster x 1
  • Observer x 1


S112 v5.1 is a highly featured, qualified Bluetooth 5 protocol stack that can significantly improve your application’s performance with its support for the following:

  • Bluetooth 5: 2Mbps datarate
  • Bluetooth 5: Channel Selection Algorithm #2
  • Configurable ATT MTU
  • LE Secure Connections
  • Link Layer Ping
  • Privacy 1.2


The S112 is delivered as a pre-qualified binary file available for download from Nordic Semiconductor. As a pre-qualified binary file it is independent of application development and allows for a much simpler, safer development process when making Bluetooth LE applications.
