I tried to read/write the internal mifare card of a 6131 with external softwares & readers.
Nokia told me the keys A & B are FFFFFFFFFFFF on my phone.
- With MifareWnd from Philips Semiconductors, it says "No Card in RF field" when we touch the Pegoda with the phone.
- With a NFC SD Card on a Pocket PC which has a standard application installed to read/write MIFARE, it finds the card but can't print the UID.
- With another application and another reader, it detects a MIFARE 4K card but we can't read/write the data blocks even if we set key A & B.
All three softwares are working with Nokia 3220 and standard MIFARE UL/1K/4K Cards. Is there something special we have to know about the internal Mifare card ? Is it a standard 4K card ? What are the access bits ? Do you know if we can set our own keys instead of using default FFFFFFFFFFFF ? Do you have a software to read/write MIFARE cards with a Pegoda ?
