    Description

      We are sending custom messages to a type 4 NFC tag by using QNearFieldTarget::sendCommand.

      The problem is that even though we can see in the output window that the replies are correct, Qt discards them with checksum errors. The code that discards messages is found in QNearFieldTagType4Symbian::decodeResponse. The actual line of code is *if
      ((command.count()> 2)&& (0x00 == command.at(0)))*.

      In our particular case the reply does not satisfy the 0x00 check, while still being valid.
