Detailed Description

MCUmgr SMP client API.

Typedef Documentation

smp_client_res_fn

typedef int(* smp_client_res_fn) (struct net_buf *nb, void *user_data)

#include <zephyr/mgmt/mcumgr/smp/smp_client.h>

Response callback for SMP send.

Parameters

nb	net_buf for response
user_data	same user data that was provided as part of the request

Returns

0 on success.

mcumgr_err_t code on failure.

Function Documentation

smp_client_buf_allocation()

struct net_buf * smp_client_buf_allocation	(	struct smp_client_object *	smp_client,
		uint16_t	group,
		uint8_t	command_id,
		uint8_t	op,
		enum smp_mcumgr_version_t	version
	)

#include <zephyr/mgmt/mcumgr/smp/smp_client.h>

Allocate buffer and initialize with SMP header.

Parameters

smp_client	SMP client object
group	SMP group id
command_id	SMP command id
op	SMP operation type
version	SMP MCUmgr version

Returns

A newly-allocated buffer net_buf on success

NULL on failure.

smp_client_buf_free()

void smp_client_buf_free

(

struct net_buf *

nb

)

#include <zephyr/mgmt/mcumgr/smp/smp_client.h>

Free a SMP client buffer.

Parameters

nb	The net_buf to free.

smp_client_object_init()

int smp_client_object_init	(	struct smp_client_object *	smp_client,
		int	smp_type
	)

#include <zephyr/mgmt/mcumgr/smp/smp_client.h>

Initialize a SMP client object.

Parameters

smp_client	The Client to construct.
smp_type	SMP transport type for discovering transport object

Returns

0 if successful

mcumgr_err_t code on failure

smp_client_send_cmd()

int smp_client_send_cmd	(	struct smp_client_object *	smp_client,
		struct net_buf *	nb,
		smp_client_res_fn	cb,
		void *	user_data,
		int	timeout_in_sec
	)

#include <zephyr/mgmt/mcumgr/smp/smp_client.h>

SMP client data send request.

Parameters

smp_client	SMP client object
nb	net_buf packet for send
cb	Callback for response handler
user_data	user defined data pointer which will be returned back to response callback
timeout_in_sec	Timeout in seconds for send process. Client will retry transport based CONFIG_SMP_CMD_RETRY_TIME

Returns

0 on success.

mcumgr_err_t code on failure.

smp_client_single_response()

int smp_client_single_response	(	struct net_buf *	nb,
		const struct smp_hdr *	res_hdr
	)

#include <zephyr/mgmt/mcumgr/smp/smp_client.h>

SMP client response handler.

Parameters

nb	response net_buf
res_hdr	Parsed SMP header

Returns

0 on success.

mcumgr_err_t code on failure.
