Nordic Semiconductor has announced S110 SoftDevice v7.0, the next major release of its Bluetooth low energy stack, for the nRF51822 Bluetooth low energy and 2,4 GHz proprietary system-on-chip (SoC) and the nRF51422 ANT and ANT/Bluetooth low energy multiprotocol SoCs. (A SoftDevice is Nordic’s self-contained stack for nRF51 series SoCs that incorporates an RF protocol and its associated management framework.) The S110 SoftDevice v7.0 brings a range of new features including over-the-air device firmware upgrade (OTA-DFU), concurrent peripheral/broadcaster roles, support for concurrent multiprotocol Bluetooth low energy/2.4GHz RF proprietary operation, and compliance with the latest version of Bluetooth wireless technology (Bluetooth v4.1) allowing end products using the S110 SoftDevice to be qualified to the Bluetooth standard. The nRF51 series SoCs’ flash-based architecture and the S110 SoftDevice’s OTA-DFU feature support a flexibility to firmware upgrades that is not possible on alternative static ROM/OTP-based ULP wireless SoCs. Now the nRF51822 and nRF51422 SoCs’ stacks and application firmware can be upgraded quickly and easily using the devices’ own wireless link.
