WifiConfig_SetSSID Function

Header: #include <applibs/wificonfig.h>

Sets the SSID for a Wi-Fi network.

The setting is effective immediately but won't persist across device reboots unless the WifiConfig_PersistConfig function is called after this function.

static int WifiConfig_SetSSID(int networkId, const uint8_t *ssid, size_t ssidLength);

Parameters

• networkId The ID of the network to configure. WifiConfig_AddNetwork returns the network ID.

• ssid A pointer to a byte array that contains the new SSID. The character encoding is not specified.

• ssidLength The number of bytes in the ssid parameter. Must be less than or equal to WIFICONFIG_SSID_MAX_LENGTH.

Errors

Returns -1 if an error is encountered and sets errno to the error value.

• EACCES: the application manifest doesn't include the WifiConfig capability.

• EFAULT: the ssid parameter is NULL.

• ERANGE: the ssidLength parameter is greater than WIFICONFIG_SSID_MAX_LENGTH.

• EAGAIN: the Wi-Fi device isn't ready.

• ENETDOWN: the Wi-Fi network interface is unavailable.

• EINVAL: the networkId parameter is invalid.

• ENODEV: the networkId parameter doesn't match any of the IDs of the stored networks.

Any other errno may also be specified; such errors aren't deterministic and the same behavior might not be retained through system updates.

Return value

Returns 0 for success, or -1 for failure, in which case errno is set to the error value.

Application manifest requirements

The application manifest must include the WifiConfig capability.
