NetHub

NetHub

NetHub bridges device-side Wi-Fi capability to a selected host interface.

The current solution targets Wi-Fi SoCs such as BL616 / BL618 / BL616CL / BL618DG.

Current Status

Item	Current status
Default interface	SDIO
USB data-path	device-side USB ECM backend implemented
USB control transport	device-side USB ACM transport plumbing implemented
SPI	not implemented
USER virtual channel	default interface is SDIO
Low power	currently BL618DG only
Optional ATModule control solution	available, but not mandatory

Document Guide

Use these documents according to what you need:

Document	Focus
NetHubQuickBringup.md	default interface, main configuration switches, build and flash, SDIO and USB pins
NetHubArchitecture.md	internal layering, public APIs, support matrix, and interface differences
NetHubVirtualChannel.md	USER virtual channel scope, prerequisites, APIs, and limits

Key Points

• SDIO is the current default interface for the in-tree bring-up path.
• USB device-side backend is implemented with ECM + ACM.
• SPI is still a stub and is not ready for bring-up.
• nethub core exposes data-path, control path, and virtual channel facades without directly depending on ATModule.
• The optional ATModule + bflbwifid + bflbwifictrl flow is available, but not mandatory.
