iButton problem

[dorasu]

Hello,

I am try to use iButton instead of RFID. RFID can send charater(eg.00FF2561), but iButton send unknown symbols. So, Do I need to change RFID code for iButton?

Please help me

Thanks in advance

If you use the DS19xx I-button it transmits the unique serial number on the button via one wire connection.

It's main purpose is access control.

Are you sure the iButton uses the same protocol as your reader?

Hi Mike,

I guess different protocols will not be the problem when reading.

The RFID chip transmits an RF signal to be converted.

The I-button is read directly via one wire connection.

There are contactless iButtons that behave like RFID devices. See **broken link removed**.

Hello,

Yes. It is same protocol as RFID reader. I only receive unknown symbols (e.g.,ˆÿžçþ„ÿ), but I can receive RFID number (e.g., 00FF2590).

How to get ibutton number as RFID?

Thanks
