You could also try other reading/writing example code in the library.
It also supports reading flexible tag. We tested flexible tags of Mifare 1 S50 and Ultralight. The reading distance is up to 5cm.
You could find those flexible tags here.
P2P NFC
Currently we are still developing the software. The P2P NFC communication between two PN532 modules is only supported by I2C
mode. Please download this library.
Note, while testing this library, please remove the libraries in the testing above (or other PN532 libraries) to other folders.
Otherwise they might conflict.
Here we need two Arduino boards to test this function. Basically we will program one NFC module as Initiator, and the other as
Target.
