just FYI, the relevant source code can be found at: https://android.googlesource.com/platform/packages/apps/Nfc/+/android-5.0.2_r1/src/com/android/nfc/NfcWifiProtectedSetup.java

If you put your payload through http://www.string-functions.com/hex-string.aspx you can decode the information.

The source code says:

/*
 * ID into configuration record for SSID and Network Key in hex.
 * Obtained from WFA Wifi Simple Configuration Technical Specification v2.0.2.1.
 */

Unfortunately the relevant document is only downloadable if you pay 99$ to the wifi alliance, but I guess you can just take the google code and develop your app accordingly.
