Hi Samo,
In the tests I have made, the content is read and don't need to tap again the tag. Check if the static method
com.sirit.nfc.Hardware.NFCRequestEnabledADD(true);
is called in the constructor of your MIDlet. Otherwise, I may not work properly.
Yes, the "JSR257 with Extensions - BenQ Integration Guide-02d.pdf" is the manual of Sirit and comes with the SDK. If you have not received, just ask me and we are going to send a copy as soon as possible.
Best regards,
Jose
