Upstream status

Baton-C is developed in its own repository and proposed to the Zephyr project as an optional module: a separate repository, listed in submanifests/optional.yml of Zephyr, with its samples and tests inside the module and no dependency of Zephyr on it. That is the integration mode Zephyr's external component process provides for a library that no Zephyr subsystem depends on. A new module needs an RFC issue and the approval of the Technical Steering Committee.

Step	Status
Zephyr module in Baton-C (zephyr/), CI with twister	Done, in review in the Baton-C repository
Baton-C v1.1.0 release with the module	Planned
Bring-up on the M2S010 MKR Kit, measurements	In progress
RFC "New External Source Code" issue in Zephyr	Planned after the hardware results
Pull request adding Baton-C to submanifests/optional.yml	Planned with the RFC
Target Zephyr release	4.6 (LTS, planned for April 2027)

Zephyr releases follow a six-month cycle; Zephyr 4.5 is in its stabilization phase, in which no new features are merged, so the earliest release that can include the module is 4.6.
