Nordic Semiconductor S130 SoftDevice Bluetooth Smart protocol stack

Nordic Semiconductor has launched the S130 SoftDevice - a Bluetooth Smart protocol stack which allows the development of Nordic nRF51 Series SoC-based advanced wearable Bluetooth Smart hub network topologies that don’t always need a smartphone present to operate. The Bluetooth 4.1 compliant protocol stack includes all Bluetooth Smart protocol layers up to and including GATT/GAP.

The product supports multilink central, peripheral, observer and broadcaster roles, GATT server and client, and event-driven, asynchronous and thread-safe GATT/GAP and L2CAP APIs. Other features include an over-the-air device firmware upgrade (OTA-DFU) capability that leverages the Nordic nRF51 Series SoCs’ flash architecture for in-the-field product firmware updates. It is a suitable choice for Bluetooth Smart hubs that are not smartphones or tablets.

The product is delivered as a SoftDevice for Nordic’s nRF51 Series ICs and, as such, it is a pre-compiled binary with no link time dependencies to application code.
