nfc_relay

NFC Relay app for flipper zero, relay NFCA APDU and response between two flipper.

TODO or LIMITATIONS

• TODO
  • configurable UART pin and baudrate (Right now is hardcored using 15/16 aka. C1/C0 and 38400)
    • baudrate bigger than 38400 will case data lost
  • other method for flipper zero to communicate.
• limitations
  • st25r3916 RFAL002 will not emulate 10 bytes NFCID easily
  • furi_hal_nfc_emulate_nfca currently are using hardcoded ATS(Answer-to-Select)

test viedo

Setup in this video are:

• flipper zero with case + wifi dev board(flashed with esp-at, using IO17/IO18 as TX/RX, config with wifi network and pass through internet AT+SAVETRANSLINK=1,"<SERVER_DOMAIN>",7771,"UDP",1005)
• flipper zero naked + m5stickc(also flashed with esp-at, using pin 25 and 26, config with wifi network and pass through internet AT+SAVETRANSLINK=1,"<SERVER_DOMAIN>",7770,"UDP",1005)
• Server on some cloud running socat socat -v -d -d udp-l:7770 udp-l:7771
