An iOS and macOS library for performing Over-The-Air Device Firmware Updates on Nordic Semiconductor nRF5x Bluetooth SoCs.
What is iOS DFU Library?
Nordic Semiconductor's iOS DFU Library is a Swift library that enables Over-The-Air Device Firmware Updates (OTA-DFU) for nRF5x Series Bluetooth SoCs from iOS and macOS devices. It solves the problem of wirelessly updating firmware on embedded devices in the field, allowing developers to fix bugs and add features post-deployment. The library handles BLE communication, bootloader switching, and firmware transfer securely and reliably.
iOS and macOS developers building applications that manage or update firmware on Nordic Semiconductor nRF5x-based Bluetooth devices, such as IoT products, wearables, or embedded systems.
Developers choose this library because it is the official, tested solution from Nordic Semiconductor, ensuring compatibility with all nRF5x DFU bootloader versions. It simplifies complex BLE update procedures, supports both Legacy and Secure DFU, and integrates easily with standard iOS dependency managers.
