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 v22.214.171.124.
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.
