Android SDK: readMailboxMessage() questions

Hi, I have a few questions about the use of the Android SDK for the ST24DV tags.


1) readMailboxMessage(0,0) allways returns a first byte which is zero. This zero-first byte seems to come from the tag itself, but I did not find any reference in the datasheet.


2) readMailboxMessage(0,1) where argument one is the mailbox adress, and argument two is the amount of bytes to read, never returns anything and the asyncrounous thread in which the function is calles terminates. Why is this?


3) fastReadMailboxMessage() and fastWriteMailboxMessage sho the same behavoir as the function call in 2). Is it possible, that these fast operation modes are not supported by my hardware (Huawei Mate 7)?


Any help would be very appreciated.

Yours, Andreas
