RF430FRL152H option flag

Other Parts Discussed in Thread: RF430FRL152H

Is there a table with the flags in a ISO15693 command, which are supported by the RF430FRL152H?

It seems that it does not support the option flag for a "Read Single Block" Command, but I could not find any information about this in the documentation.

best regards,

Martin

    Martin -
    you are referring to the use of the option flag biti n the request flags byte when using the optional command "Read Single Block", which results in the transponder returning the contents of the block and the security status of that block.

    should work - are you using the device in 4 byte or 8 byte block mode? which block address(es) are you attempting to read?

    I'm using it in the 8 Byte mode and the RF430FRL152H answers with 9 Bytes (without CRC). But it should be 10 Bytes with 1 Byte Flags + 1 Byte security status + 8 Bytes Data . I tried to read the Firmware System Control Register (Block 0xFF) and the Firmware Version Register (Block 0xFB). Are they handled differently ?

    regards,

    Yes "Firmware System Control Register (Block 0xFF) and the Firmware Version Register (Block 0xFB)." are handled differently.  They are only responded to with read/write single block command and no options are serviced. These blocks also cannot be locked.

    Regarding which ISO15693 commands are supported, they are listed below:

    inventory (1-slot and 16-slot, AFI flag not supported)
    read single block (option flag supported)
    read multiple block (option flag supported, max 3 blocks in 8-byte mode, 6 in 4-byte mode)
    select command
    write single block (no options supported)
    write multiple blocks (no options supported)
    lock block command
    stay quite command
    reset to ready command
    get system info
