Distributor model
A distributor node receives or stores the image and manages distribution through the mesh to multiple targets.
Bluetooth Mesh FOTA
Fleet-scale firmware distribution architecture.
Target model
Target nodes validate metadata, receive block/chunk data, verify integrity, and apply the image according to rollout policy.
Hybrid deployment
Use mesh for orchestration and staging while keeping direct OTA available where speed is more important than one-to-many distribution.
From Lighting Fast OTA to Lighting Fast Mesh FOTA
The direct OTA metadata, versioning, integrity model, and activation policy can be preserved while the transport becomes mesh-native.
Mapping
- Control metadata stays
- Data packets become blocks/chunks
- Missing-packet recovery becomes block/chunk recovery
- Final completion becomes distributed verify/apply state
