Function Documentation

wifi_credentials_delete_all()

int wifi_credentials_delete_all

(

void

)

#include <zephyr/net/wifi_credentials.h>

Deletes all stored Wi-Fi credentials.

This function deletes all Wi-Fi credentials that have been stored in the system. It is typically used when you want to clear all saved networks.

Returns

0 on successful, otherwise a negative error code

wifi_credentials_delete_by_ssid()

int wifi_credentials_delete_by_ssid	(	const char *	ssid,
		size_t	ssid_len )

#include <zephyr/net/wifi_credentials.h>

Delete credentials for given SSID.

Parameters

[in]	ssid	SSID to look for
[in]	ssid_len	length of SSID

Returns

-ENOENT if No network with this SSID was found.

0 on success, otherwise a negative error code

wifi_credentials_for_each_ssid()

void wifi_credentials_for_each_ssid	(	wifi_credentials_ssid_cb	cb,
		void *	cb_arg )

#include <zephyr/net/wifi_credentials.h>

Call callback for each registered SSID.

Parameters

cb	callback
cb_arg	argument for callback function

wifi_credentials_get_by_ssid_personal()

int wifi_credentials_get_by_ssid_personal	(	const char *	ssid,
		size_t	ssid_len,
		enum wifi_security_type *	type,
		uint8_t *	bssid_buf,
		size_t	bssid_buf_len,
		char *	password_buf,
		size_t	password_buf_len,
		size_t *	password_len,
		uint32_t *	flags,
		uint8_t *	channel,
		uint32_t *	timeout )

#include <zephyr/net/wifi_credentials.h>

Get credentials for given SSID.

Parameters

[in]	ssid	SSID to look for

[in]	password_buf_len	length of password_buf
[out]	password_len	length of password
[out]	flags	flags
[out]	channel	channel
[out]	timeout	timeout

Returns

0 Success.

-ENOENT No network with this SSID was found.

-EINVAL A required buffer was NULL or invalid SSID length.

-EPROTO The network with this SSID is not a personal network.

wifi_credentials_get_by_ssid_personal_struct()

int wifi_credentials_get_by_ssid_personal_struct	(	const char *	ssid,
		size_t	ssid_len,
		struct wifi_credentials_personal *	buf )

#include <zephyr/net/wifi_credentials.h>

Get credentials for given SSID by struct.

Parameters

[in]	ssid	SSID to look for
[in]	ssid_len	length of SSID

wifi_credentials_is_empty()

bool wifi_credentials_is_empty

(

void

)

#include <zephyr/net/wifi_credentials.h>

Check if credentials storage is empty.

Returns

true if credential storage is empty, otherwise false

wifi_credentials_set_personal()

int wifi_credentials_set_personal	(	const char *	ssid,
		size_t	ssid_len,
		enum wifi_security_type	type,
		const uint8_t *	bssid,
		size_t	bssid_len,
