Example Firmware Packages
These images were copied from the Nordic nRF5 SDK version 14.2.0.
An entire device firmware can be broken down into three images, each of which can be update separately:
- Soft Device
- Bootloader
- Application
Each package can have up to two images in it, the first of which is one of the following:
- Soft Device
- Bootloader
- Soft Device and Bootloader
The second image can then be an application image.

This package contains a single bootloader image which allows further updates from boot.
softdevice_bootloader_secure_ble_s132.zip
This package contains a single image contaning both a soft device and a bootloader.
