Function Documentation

bt_mesh_dfu_metadata_comp_hash_get()

int bt_mesh_dfu_metadata_comp_hash_get	(	struct net_buf_simple *	buf,
		uint8_t *	key,
		uint32_t *	hash
	)

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

Compute hash of the Composition Data state.

The format of the Composition Data is defined in MshPRTv1.1: 4.2.2.1.

Parameters

buf	Pointer to buffer holding Composition Data.
key	128-bit key to be used in the hash computation.
hash	Pointer to a memory location to which the hash will be stored.

Returns

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

bt_mesh_dfu_metadata_comp_hash_local_get()

int bt_mesh_dfu_metadata_comp_hash_local_get	(	uint8_t *	key,
		uint32_t *	hash
	)

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

Compute hash of the Composition Data Page 0 of this device.

Parameters

key	128-bit key to be used in the hash computation.
hash	Pointer to a memory location to which the hash will be stored.

Returns

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

bt_mesh_dfu_metadata_decode()

int bt_mesh_dfu_metadata_decode	(	struct net_buf_simple *	buf,
		struct bt_mesh_dfu_metadata *	metadata
	)

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

Decode a firmware metadata from a network buffer.

Parameters

buf	Buffer containing a raw metadata to be decoded.
metadata	Pointer to a metadata structure to be filled.

Returns

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

bt_mesh_dfu_metadata_encode()

int bt_mesh_dfu_metadata_encode	(	const struct bt_mesh_dfu_metadata *	metadata,
		struct net_buf_simple *	buf
	)

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

Encode a firmware metadata into a network buffer.

Parameters

metadata	Firmware metadata to be encoded.
buf	Buffer to store the encoded metadata.

Returns

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