ST25 NFC/RFID tags and readers

Resolved! When attempting to write to the mailbox, by calling getReaderInterface() vs writeMailboxMessage() TAG_NOT_IN_THE_FIELD is returned (even though it definitely is)

We have a problem, we are trying to upload a new firmware version over NFC, using the mailbox. Our bootloader is tight on space, so we came up with a simple protocol for it; When attempting to write to the mailbox by calling mNfcTag.writeMailboxMessa...
