NFC

Record (NFC)

The NFC Record class specifies the custom data to be sent via NFC. This section describes the methods you may need to use BLE.setCustomData().

setTnf();

// PROTOTYPE
void setTnf(Tnf tnf)

The valid values for Record::Tnf are:

• TNF_EMPTY (0x00)
• TNF_WELL_KNOWN (0x01)
• TNF_MIME_MEDIA (0x02)
• TNF_ABSOLUTE_URI (0x03)
• TNF_EXTERNAL_TYPE (0x04)
• TNF_UNKNOWN (0x05)
• TNF_UNCHANGED (0x06)
• TNF_RESERVED (0x07)

setType()

Set the type field in the NFC record.

// PROTOTYPE
size_t setType(const void* type, uint8_t numBytes);

setId()

The ID field is optional in NFC. If you are using the ID, call this method to set the value. It will automatically set the IL field in the header.

// PROTOTYPE
size_t setId(const void* id, uint8_t numBytes);

setPayload()

Appends to the NFC record payload.

// PROTOTYPE
size_t setPayload(const void* payload, size_t numBytes);

Returns the number of bytes added (numBytes).
