S110 SoftDevice v7.0, the next major release of Nordic Semiconductor’s Bluetooth low energy stack, is now available 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 latest revision 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/2,4 GHz RF proprietary operation, and compliance with the latest version of Bluetooth wireless technology (Bluetooth v4.1) allowing end products to be qualified to the Bluetooth standard.
During concurrent protocol handling, Bluetooth low energy operates from the S110 SoftDevice itself while the 2,4 GHz proprietary protocol runs from the application space. The S110 SoftDevice manages all radio scheduling through application programming interfaces (API).
The nRF51 SoCs’ Flash-based architecture and the S110 SoftDevice’s OTA-DFU feature open up a flexibility for 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.
The OTA-DFU feature allows complete application and protocol stack upgrades and is not limited to just partial updates and patching. When using it, firmware upgrades can be delivered in a variety of ways depending on the chip’s use case. Nordic provides an iOS or Android smartphone app that demonstrates this flexibility.
