Enumeration Type Documentation

◆ conn_mgr_if_flag

enum conn_mgr_if_flag

#include <include/zephyr/net/conn_mgr_connectivity.h>

Per-iface connectivity flags.

Enumerator

CONN_MGR_IF_PERSISTENT

Persistent.

When set, indicates that the connectivity implementation bound to this iface should attempt to persist connectivity by automatically reconnecting after connection loss.

CONN_MGR_IF_NO_AUTO_CONNECT

No auto-connect.

When set, conn_mgr will not automatically attempt to connect this iface when it reaches admin-up.

CONN_MGR_IF_NO_AUTO_DOWN

No auto-down.

When set, conn_mgr will not automatically take the iface admin-down when it stops trying to connect, even if CONFIG_NET_CONNECTION_MANAGER_AUTO_IF_DOWN is enabled.

Function Documentation

◆ conn_mgr_if_connect()

int conn_mgr_if_connect ( struct net_if * iface )

#include <include/zephyr/net/conn_mgr_connectivity.h>

Connect interface.

If the provided iface has been bound to a connectivity implementation, initiate network connect/association.

Automatically takes the iface admin-up (by calling net_if_up) if it isn't already.

Non-Blocking.

Parameters

iface Pointer to network interface

Return values

0	on success.
-ESHUTDOWN	if the iface is not admin-up.
-ENOTSUP	if the iface does not have a connectivity implementation.
implementation-specific	status code otherwise.

◆ conn_mgr_if_disconnect()

int conn_mgr_if_disconnect ( struct net_if * iface )

#include <include/zephyr/net/conn_mgr_connectivity.h>

Disconnect interface.

If the provided iface has been bound to a connectivity implementation, disconnect/disassociate it from the network, and cancel any pending attempts to connect/associate.

Does nothing if the iface is currently admin-down.

Parameters

iface Pointer to network interface

Return values

0	on success.
-ENOTSUP	if the iface does not have a connectivity implementation.
implementation-specific	status code otherwise.

◆ conn_mgr_if_get_flag()

bool conn_mgr_if_get_flag	(	struct net_if *	iface,
		enum conn_mgr_if_flag	flag
	)

#include <include/zephyr/net/conn_mgr_connectivity.h>

Check the value of connectivity flags.

If the provided iface is bound to a connectivity implementation, retrieves the value of the specified connectivity flag associated with that iface.

Parameters

iface	- Pointer to the network interface to check.
flag	- The flag to check.

Returns: True if the flag is set, otherwise False. Also returns False if the provided iface is not bound to a connectivity implementation, or the requested flag doesn't exist.

◆ conn_mgr_if_get_opt()

int conn_mgr_if_get_opt	(	struct net_if *	iface,
		int	optname,
		void *	optval,
		size_t *	optlen
	)

#include <include/zephyr/net/conn_mgr_connectivity.h>

Get implementation-specific connectivity options.

If the provided iface has been bound to a connectivity implementation that supports it, retrieves implementation-specific connectivity options related to the iface.

Parameters

iface	Pointer to the network interface.
optname	Integer value representing the option to set. The meaning of values is up to the conn_mgr_conn_api implementation. Some settings may be shared by multiple ifaces.
optval	Pointer to where the retrieved value should be stored.
optlen	Pointer to length (in bytes) of the destination buffer available for storing the retrieved value. If the available space is less than what is needed, -ENOBUFS is returned. If the available space is invalid, -EINVAL is returned.

optlen will always be set to the total number of bytes written, regardless of whether an error is returned, even if zero bytes were written.

Return values

0	if successful.
-ENOTSUP	if conn_mgr_if_get_opt is not implemented by the iface.
-ENOBUFS	if retrieval buffer is too small.
-EINVAL	if invalid retrieval buffer length is provided, or if NULL optval or optlen pointer provided.
-ENOPROTOOPT	if the optname is not recognized.
implementation-specific	error code otherwise.

◆ conn_mgr_if_get_timeout()

int conn_mgr_if_get_timeout ( struct net_if * iface )

#include <include/zephyr/net/conn_mgr_connectivity.h>

Get the connectivity timeout for an iface.

If the provided iface is bound to a connectivity implementation, retrieves the timeout setting in seconds for it.

Parameters

iface - Pointer to the iface to check.

Returns: int - The connectivity timeout value (in seconds) if it could be retrieved, otherwise CONN_MGR_IF_NO_TIMEOUT.

◆ conn_mgr_if_is_bound()

bool conn_mgr_if_is_bound ( struct net_if * iface )

#include <include/zephyr/net/conn_mgr_connectivity.h>

Check whether the provided network interface supports connectivity / has been bound to a connectivity implementation.

Parameters

iface Pointer to the iface to check.

Return values

true	if connectivity is supported (a connectivity implementation has been bound).
false	otherwise.

◆ conn_mgr_if_set_flag()

int conn_mgr_if_set_flag	(	struct net_if *	iface,
		enum conn_mgr_if_flag	flag,
		bool	value
	)

#include <include/zephyr/net/conn_mgr_connectivity.h>

Set the value of a connectivity flags.

If the provided iface is bound to a connectivity implementation, sets the value of the specified connectivity flag associated with that iface.

Parameters

iface	- Pointer to the network interface to modify.
flag	- The flag to set.
value	- Whether the flag should be enabled or disabled.

Return values

0	on success.
-EINVAL	if the flag does not exist.
-ENOTSUP	if the provided iface is not bound to a connectivity implementation.

◆ conn_mgr_if_set_opt()

int conn_mgr_if_set_opt	(	struct net_if *	iface,
		int	optname,
		const void *	optval,
		size_t	optlen
	)

#include <include/zephyr/net/conn_mgr_connectivity.h>

Set implementation-specific connectivity options.

If the provided iface has been bound to a connectivity implementation that supports it, implementation-specific connectivity options related to the iface.

Parameters

iface	Pointer to the network interface.
optname	Integer value representing the option to set. The meaning of values is up to the conn_mgr_conn_api implementation. Some settings may affect multiple ifaces.
optval	Pointer to the value to be assigned to the option.
optlen	Length (in bytes) of the value to be assigned to the option.

Return values

0	if successful.
-ENOTSUP	if conn_mgr_if_set_opt not implemented by the iface.
-ENOBUFS	if optlen is too long.
-EINVAL	if NULL optval pointer provided.
-ENOPROTOOPT	if the optname is not recognized.
implementation-specific	error code otherwise.

◆ conn_mgr_if_set_timeout()

int conn_mgr_if_set_timeout	(	struct net_if *	iface,
		int	timeout
	)

#include <include/zephyr/net/conn_mgr_connectivity.h>

Set the connectivity timeout for an iface.

If the provided iface is bound to a connectivity implementation, sets the timeout setting in seconds for it.

Parameters

iface	- Pointer to the network interface to modify.
timeout	- The timeout value to set (in seconds). Pass CONN_MGR_IF_NO_TIMEOUT to disable the timeout.

Return values

0	on success.
-ENOTSUP	if the provided iface is not bound to a connectivity implementation.
