HydraFW HydraNFC v2 guide

HydraNFC Shield v2 must be plugged on the front side of HydraBus! (PowerOff the HydraBus before to plug HydraNFC)

This guide is updated towards firmware release HydraBus v1 HydraNFC Shield v2 firmware v0.1 Beta (HydraFW (HydraBus v1/HydraNFC Shield v2) v0.1-beta-38-g1674a04 2020-08-16)

Read UID of any NFC(ISO14443A, ISO14443B, ISO15693, FELICA) Tag (NFC-A/B/V/F)

• Using console type nfc + Enter to enter NFC mode dedicated to HydraNFC Shield v2.
• Choose the NFC technology to select for scan command using nfc-all (Note: you do not need to repeat this command all the time)
• Example to read Type A Tag (MIFARE Classic MF1ICS50), place the tag on NFC Antenna and type following commands:

NFC> nfc-all
NFC> scan
NFC-A 106-106 kb/s Type=0x00 ATQA=0x0004 SAK=0x08 UID:CD815F76

• Example to read Type B Tag, place the tag on NFC Antenna and type following commands:

NFC> nfc-all
NFC> scan
NFC-B 106-106 kb/s UID:00422099

• Example to read Type V Tag (ST25), place the tag on NFC Antenna and type following commands:

NFC> nfc-all
NFC> scan
NFC-V 26-26 kb/s UID:E00223001886A91D

You can also define options for scan like continuous mode and its period (in millisecond) (default period is 1000ms).

You can also read multiple tags (so far up to 4 on the reader) at same time as the firmware support full anti-collision (thanks to ST RFAL).

Selection of specific NFC technology

You can use nfc-a, nfc-b, nfc-st25tb, nfc-v or nfc-f to select a specific NFC technology to be used with scan command

See help or press Tab for all commands:

Connect, Send APDU data

• connect Connect to a smartcard (ISO 14443 A & B)
• send Send APDU data to a card initialized with the connect command (only ISO 14443 A & B tags) Example usage:

NFCv2> connect
> 26
< 04 00 
> 93 20 
< B9 CC 13 71 17

NFC Emulation ISO 14443A

Emulation ISO 14443A Tag UID

• Example usage for 4 bytes UID:
  • ce uid 01020304 sak 20
  • emul-3a
• Example usage for 7 bytes UID:
  • ce uid 01020304050607 sak 20
  • emul-3a

Emulation ISO 14443A Tag (UID 4 or 7 Bytes), SAK(configurable), NDEF with Data URI

• Example usage 4 bytes UID:
  • ce uid 01020304 sak 20 uri "hydrabus.com"
  • emul-t4t uri
• Example usage 7 bytes UID:
  • ce uid 01020304050607 sak 20 uri "hydrabus.com"
  • emul-t4t uri
