Hallo Saurabh, > What is the significance of this : > >>I just looked through my code and found that I also explicitly disabled >>ISO 14443-4 activation (before polling) using this command: >> FF00000003D41224
See page 9 of the reader API manual: "Some Type A Tags may support both ISO14443-3 Type A and ISO14443-4 Type A operating modes. For example, JCOP30 supports MIFARE 1K emulation (ISO14443-3) and ISO14443-4. If the reader sends a RATS command to the tag, the ISO14443-4 mode will be activated, or the tag remains in MIFARE 1K emulation mode (ISO14443-3). It is up to the application to decide which operating mode to be activated. By default, the reader will perform automatic ISO14443-4 activation if the tag supports ISO14443-4. * To disable automatic ISO14443-4 activation: FF 00 00 00 03 D4 12 24 * To Enable automatic ISO14443-4 activation: FF 00 00 00 03 D4 12 34" So you need to disable ISO 14443-4 activation *before* you start the anti-collision sequence. Once the RATS command is sent, the SmartMX will not accept raw MIFARE classic commands anymore. br Michael -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
