nfc - NFC Interaction

Interact with DUT using NFC. Requires a supported NFC interface adapter device.

nfc ntag-detect - Detect and identify NFC tags.

Checks if an NFC NTAG is present at the adapter and reads its UID. Fails if no tag is detected.

Usage:

- command: nfc ntag-detect
  [extractKey: <uid>]
  [retry: <retryCount>]

Argument	Description
uid	The NTAG UID value can be extracted as a User Key (optional)
retryCount	Number of times to retry the test step (optional)

Use nfc ntag-detect to confirm tag presence (and capture its UID) before or after an nfc write step. For example, this can be used to verify a tag was placed on the fixture, or to read back a UID for the report.

nfc write - Write NFC tag data.

Encode one or more NDEF records and write the resulting NDEF message to the tag presented at the NFC adapter.

Usage:

- command: nfc write <TAGTYPE> <payload>...
  [retry: <retryCount>]

Argument	Description
tagtype	Tag type (`NTAG203`, `NTAG213` or `NTAG216`). Required argument; writing auto-detects the presented NDEF tag rather than branching on this value.
payload	One or more NDEF records to write. Currently only `text:<string>` (an NDEF Text record, language `en`) is supported. Other prefixes are rejected.
retryCount	Number of times to retry the test step (optional)

Each payload argument becomes one NDEF record in the message written to the tag, in the order given.
