WifiConfig_SetPSK Function

  • Raksts

Header: #include <applibs/wificonfig.h>

Sets the pre-shared key (PSK) for a Wi-Fi network. The PSK is used for networks that are configured with the WifiConfig_Security_Wpa2_Psk security type.

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_SetPSK(int networkId, const char *psk, size_t pskLength);

Parameters

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

  • psk A pointer to the buffer that contains the PSK for the network.

  • pskLength The length of the PSK for the network. This parameter must be less than or equals to WIFICONFIG_WPA2_KEY_MAX_BUFFER_SIZE.

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 psk parameter is NULL.

  • ERANGE: the pskLength parameter is greater than WIFICONFIG_WPA2_KEY_MAX_BUFFER_SIZE.

  • 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.
