typedef enum bt_mesh_dfu_iter(* bt_mesh_dfu_img_cb_t) (struct bt_mesh_dfu_cli *cli, struct bt_mesh_msg_ctx *ctx, uint8_t idx, uint8_t total, const struct bt_mesh_dfu_img *img, void *cb_data)

#include <zephyr/bluetooth/mesh/dfu_cli.h>

DFU image callback.

The image callback is called for every DFU image on the Target node when calling bt_mesh_dfu_cli_imgs_get.

Parameters

cli	Firmware Update Client model instance.
ctx	Message context of the received message.
idx	Image index.
total	Total number of images on the Target node.
img	Image information for the given image index.
cb_data	Callback data.

Return values

BT_MESH_DFU_ITER_STOP	Stop iterating through the image list and return from bt_mesh_dfu_cli_imgs_get.
BT_MESH_DFU_ITER_CONTINUE	Continue iterating through the image list if any images remain.

Function Documentation

◆ bt_mesh_dfu_cli_apply()

int bt_mesh_dfu_cli_apply ( struct bt_mesh_dfu_cli * cli )

#include <zephyr/bluetooth/mesh/dfu_cli.h>

Apply the completed DFU transfer.

A transfer can only be applied after it has ended successfully. The Firmware Update Client's applied callback is called at the end of the apply procedure.

Parameters

cli	Firmware Update Client model instance.

Returns: 0 on success, or (negative) error code otherwise.

◆ bt_mesh_dfu_cli_cancel()

int bt_mesh_dfu_cli_cancel	(	struct bt_mesh_dfu_cli *	cli,
		struct bt_mesh_msg_ctx *	ctx
	)

#include <zephyr/bluetooth/mesh/dfu_cli.h>

Cancel a DFU transfer.

Will cancel the ongoing DFU transfer, or the transfer on a specific Target node if ctx is valid.

Parameters

cli	Firmware Update Client model instance.
ctx	Message context, or NULL to cancel the ongoing DFU transfer.

Returns: 0 on success, or (negative) error code otherwise.

◆ bt_mesh_dfu_cli_confirm()

int bt_mesh_dfu_cli_confirm ( struct bt_mesh_dfu_cli * cli )

#include <zephyr/bluetooth/mesh/dfu_cli.h>

Confirm that the active transfer has been applied on the Target nodes.

A transfer can only be confirmed after it has been applied. The Firmware Update Client's confirmed callback is called at the end of the confirm procedure.

Target nodes that have reported the effect as BT_MESH_DFU_EFFECT_UNPROV are expected to not respond to the query, and will fail if they do.

Parameters

cli	Firmware Update Client model instance.

Returns: 0 on success, or (negative) error code otherwise.

◆ bt_mesh_dfu_cli_imgs_get()

int bt_mesh_dfu_cli_imgs_get	(	struct bt_mesh_dfu_cli *	cli,
		struct bt_mesh_msg_ctx *	ctx,
		bt_mesh_dfu_img_cb_t	cb,
		void *	cb_data,
		uint8_t	max_count
	)

#include <zephyr/bluetooth/mesh/dfu_cli.h>

Perform a DFU image list request.

Requests the full list of DFU images on a Target node, and iterates through them, calling the cb for every image.

The DFU image list request can be used to determine which image index the Target node holds its different firmwares in.

Waits for a response until the procedure timeout expires.

Parameters

cli	Firmware Update Client model instance.
ctx	Message context.
cb	Callback to call for each image index.
cb_data	Callback data to pass to `cb`.
max_count	Max number of images to return.

Returns: 0 on success, or (negative) error code otherwise.

◆ bt_mesh_dfu_cli_is_busy()

bool bt_mesh_dfu_cli_is_busy ( struct bt_mesh_dfu_cli * cli )

#include <zephyr/bluetooth/mesh/dfu_cli.h>

Check whether a DFU transfer is in progress.

Parameters

cli	Firmware Update Client model instance.

Returns: true if the BLOB Transfer Client is currently participating in a transfer, false otherwise.

◆ bt_mesh_dfu_cli_metadata_check()

int bt_mesh_dfu_cli_metadata_check	(	struct bt_mesh_dfu_cli *	cli,
		struct bt_mesh_msg_ctx *	ctx,
		uint8_t	img_idx,
		const struct bt_mesh_dfu_slot *	slot,
		struct bt_mesh_dfu_metadata_status *	rsp
	)

#include <zephyr/bluetooth/mesh/dfu_cli.h>

Perform a metadata check for the given DFU image slot.

The metadata check procedure allows the Firmware Update Client to check if a Target node will accept a transfer of this DFU image slot, and what the effect would be.

Waits for a response until the procedure timeout expires.

Parameters

cli	Firmware Update Client model instance.
ctx	Message context.
img_idx	Target node's image index to check.
slot	DFU image slot to check for.
rsp	Metadata status response buffer.

Returns: 0 on success, or (negative) error code otherwise.

uint8_t bt_mesh_dfu_cli_progress ( struct bt_mesh_dfu_cli * cli )

#include <zephyr/bluetooth/mesh/dfu_cli.h>

Get progress as a percentage of completion.

Parameters

cli	Firmware Update Client model instance.

Returns: The progress of the current transfer in percent, or 0 if no transfer is active.

◆ bt_mesh_dfu_cli_resume()

int bt_mesh_dfu_cli_resume ( struct bt_mesh_dfu_cli * cli )

#include <zephyr/bluetooth/mesh/dfu_cli.h>

Resume the suspended transfer.

Parameters

cli	Firmware Update Client instance.

Returns: 0 on success, or (negative) error code otherwise.

◆ bt_mesh_dfu_cli_send()

int bt_mesh_dfu_cli_send	(	struct bt_mesh_dfu_cli *	cli,
		const struct bt_mesh_blob_cli_inputs *	inputs,
		const struct bt_mesh_blob_io *	io,
		const struct bt_mesh_dfu_cli_xfer *	xfer
	)

#include <zephyr/bluetooth/mesh/dfu_cli.h>

Start distributing a DFU.

Starts distribution of the firmware in the given slot to the list of DFU Target nodes in ctx. The transfer runs in the background, and its end is signalled through the bt_mesh_dfu_cli_cb::ended callback.

Note: The BLOB Transfer Client transfer inputs targets list must point to a list of bt_mesh_dfu_target nodes.

Parameters

cli	Firmware Update Client model instance.
inputs	BLOB Transfer Client transfer inputs.
io	BLOB stream to read BLOB from.
xfer	Firmware Update Client transfer parameters.

Returns: 0 on success, or (negative) error code otherwise.

	)

#include <zephyr/bluetooth/mesh/dfu_cli.h>

Get the status of a Target node.

cli	Firmware Update Client model instance.
ctx	Message context.
rsp	Response data buffer.

Returns: 0 on success, or (negative) error code otherwise.

◆ bt_mesh_dfu_cli_suspend()

#include <zephyr/bluetooth/mesh/dfu_cli.h>

Suspend a DFU transfer.

Parameters

cli	Firmware Update Client instance.

Returns: 0 on success, or (negative) error code otherwise.

◆ bt_mesh_dfu_cli_timeout_get()

int32_t bt_mesh_dfu_cli_timeout_get ( void )

#include <zephyr/bluetooth/mesh/dfu_cli.h>

Get the current procedure timeout value.

Returns: The configured procedure timeout.

◆ bt_mesh_dfu_cli_timeout_set()

void bt_mesh_dfu_cli_timeout_set ( int32_t timeout )

#include <zephyr/bluetooth/mesh/dfu_cli.h>

Set the procedure timeout value.

Parameters

timeout The new procedure timeout.
