I'm trying to use a pair of rc531 boards to bridge between the card and reader, and analyze character streams passing between them. There is an app called NFC SPY can easily control 2 android phones to bridge between the card and the reader. I want to know what (cos) commands to set the 531 to behave just output any streams converted from NFC 14443B physical signal without to to identify any card number or Device ID or any poking into the stream. Attached is the NFC SPY bridge data stream result
