Nordic SoftDevices are Bluetooth protocol stacks that are pre-compiled binaries without runtime dependencies. This allows developers to design their applications interaction with the SoftDevice such that they experience predictable and reliable operation.
A stable hardware helper
In essence, a SoftDevice can be viewed similar to a hardware peripheral from a developer's point of view with clear interfaces and predictable behaviour. Because SoftDevices are complete and qualified when we deliver them, they are unaffected by the ‘develop and
compile’ cycle of application development and always remain stable.
The nRF5 SDK for nRF52 and nRF51 Series and the range of SoftDevices are designed to work together seamlessly, offering you as a developer an easy-to-use solution for building wireless applications.
Tested and proven in countless applications, Nordic SoftDevices come as part of the nRF5 Software Development Kit (nRF5 SDK) or can also be downloaded separately.
