Preface: Modules vs. Targets

In the context of a system devices are called a modules. This differs from the Bosch IoT Rollouts terminology where target is used to address not only a device, but also a complete system and particular parts of a device. Additionally: Modules can have a target representation if they are updatable, but can also exist only within the system as not-updatable modules.

System repository

• System management: Manage systems consisting of a gateway and multiple updatable and non-updatable modules.

• System identification: Algorithm and options on how a system is identified by a set of modules.

• System lifecycle: Handle creation of systems and modifications on the set of modules within the system.

Recipe management

• Recipe lifecycle: Differentiates between draft, release-candidate (limited access for testing), released and retired.

• 4-eyes principle: Require an additional approval for releaseing recipes.

• Signatures: Detect undesired modifications of released recipes.

• Recipe file: Customizable recipe transformation to a format which is understood by the system's gateway - default transformation/example:

  • SWUpdate: sw-description (JSON)

System update management

• Recipe match: Identify the latest matching recipe for a specific system.

• Flexibility: Enable online and offline update scenarios.

• Update history: Track the latest known state of a system and the included modules, as well as not successful operations.

• Compliance: Concepts to support the delivery release-notes and retrieval of user consent

Interfaces

• Graphical user interface for managing systems and recipes.

• HTTP/REST APIs (with Swagger documentation), in particular:
  

  • a user-facing API for managing and listing content,

  • a device facing API exposing recipes and software to be installed on systems.

Authentication

• Bosch.IdM integration

• Bosch IoT Rollouts Auth - OAuth2 clients

• Bosch User Hub + Single Key ID

Scaling

• Build on and with the robust foundation of Bosch IoT Rollouts

• Scales from 1 to millions of devices

• Worldwide distribution of update (except countries where legal restrictions apply).
