Question about NDEF record

Hi, 

I want to operate reader board in CE mode. 

I posted the question before and I got the resolution from STSW-ST25R016 library.

 

I have more questions about ndef_type_wifi.h file.

Looking at the header file, you support it as below, but I would like to check the value of the macro again. 

Is it correct value?


And is the type after the written version not supported? (ex. wpa3, sae, etc.)

#define NDEF_WIFI_AUTHENTICATION_NONE 0U /*!< WPS No Authentication (Should be 1, but set to 0 for Android native support) */
#define NDEF_WIFI_AUTHENTICATION_WPAPSK 2U /*!< WPS Authentication based on WPAPSK */
#define NDEF_WIFI_AUTHENTICATION_SHARED 3U /*!< WPS Authentication */
#define NDEF_WIFI_AUTHENTICATION_WPA 4U /*!< WPS Authentication based on WPA */
#define NDEF_WIFI_AUTHENTICATION_WPA2 5U /*!< WPS Authentication based on WPA2 */
#define NDEF_WIFI_AUTHENTICATION_WPA2PSK 6U /*!< WPS Authentication based on WPA2PSK */


#define NDEF_WIFI_ENCRYPTION_NONE 0U /*!< WPS No Encryption (Should be 1, but set to 0 for Android native support) */
#define NDEF_WIFI_ENCRYPTION_WEP 2U /*!< WPS Encryption based on WEP */
#define NDEF_WIFI_ENCRYPTION_TKIP 3U /*!< WPS Encryption based on TKIP */
#define NDEF_WIFI_ENCRYPTION_AES 4U /*!< WPS Encryption based on AES */

 

 Best regards,

    Hi eagles64,

    if I am not wrong, the latest version of the "Wi-Fi Protected Setup™ Specification" [1] is v2.0.8 (2020-12-01). It defines various Authentication Types in Table 32 but WPA3 is not covered by this specification. "Wi-Fi Easy Connect™" was introduced by the Wi-Fi Alliance (WFA) as an alternative to Wi-Fi Protected Setup (WPS). See Wi-Fi Easy Connect for more information about the support of "Wi-Fi Easy Connect™" versus WPS in Android and see as well the  "Wi-Fi Easy Connect™ specification" [2] for technical details.

    Basically,  "Wi-Fi Easy Connect™" uses an NDEF URI Record (see §5.4.3 in [2]). URI records are supported in the NDEF library.

    Regarding your question about the NDEF_WIFI_AUTHENTICATION_xxx defines, those macros should not be used to encode the Authentication Type. The authentication field of the ndefTypeWifi structure should use the value from Table 32 in [1].
