NFC Create Ndef Message

Kalipso - Form - Actions - Actions Description - Group RFID - NFC Create Ndef Message

Creates or adds a new NDEF record to an existing message. You must create an NDEF Message to be able to wright into an NFC Tag or Device.

Action available for the following operating systems:

Parameters

• Option numeric - Specifies whether to create a new message or add a record to an existing one. It can be one of:

  • 1 - Create new Message - Creates a new NDEF message with a single record.

  • 2 - Add Record to Existing Message - Adds a new NDEF record to an existing NDEF message specified in the Source NDEF Message parameter.

• Source NDEF Message string - NDEF message to add the new record to. When adding a record to an existing NDEF message, this parameter receives the existing NDEF message to add the new record to.

For this last parameter you must take into account that it is only available if Option is set to 2 - Create new Message.

• Target for NDEF Message string - The control or variable that will receive the new NDEF message.

• Record Type - The type of record to be created. It can be one of:

  • Raw Data - Allows you to manually specify the content of the NDEF elements.

    • TNF numeric - Specifies the Type Name Field of the Record. It can be one of:

      • 0 - Empty - Indicates no type, id, or payload is associated with this NDEF Record. This record type is useful on newly formatted cards since every NDEF tag must have at least one NDEF Record.

      • 1 - Well known - Indicates the type field uses the RTD type name format. This type name is used to store any record defined by a Record Type Definition (RTD), such as storing RTD Text, RTD URIs, etc., and is one of the mostly frequently used and useful record types.

      • 2 - MIME Media - Indicates the payload is an intermediate or final chunk of a chunked NDEF Record.

      • 3 - Absolute URI - Indicates the type field contains a value that follows the absolute-URI BNF construct defined by RFC 3986 .

      • 4 - External Type - Indicates the type field contains a value that follows the RTD external name specification.

      • 5 - Unknown - Indicates the payload type is unknown.

      • 6 - Unchanged - Indicates the payload is an intermediate or final chunk of a chunked NDEF Record.

      • 7 - Reserved - Reserved by the NFC Forum for future use.

    • Type string - The type of the record.

    • Payload string - The content of the record. This is saved without any encoding done by Kalipso. Encode with StringToUTF8() for example if you need to pass Unicode text, or other type of encoding.

    • ID string (optional) - The content of the record.

  • URI - Creates an Uniform Resource Identifier record.

    • Uri string - The URI value for this record.

    • ID string (optional) - The ID of the record.

  • Text - Creates a Text record.

    • Language code string - Language code for this record (en, pt, …).

    • Text string - Text content for this record.

    • ID string (optional) - The ID of the record.

  • MIME - Creates a MIME record.

    • Data string - The mime data content for this record.

    • ID string (optional) - The ID of the record.

  • Smart Poster - Creates a Smart Poster record.

    • Message string - The smart poster message. This can be an NDEF message previously created with another call to this action.

    • ID string (optional) - The ID of the record.

  • External - Creates an External Type record, normally used to pass application specific data.

    • Domain string - The domain for this external type record.

    • Type string - The type of data for this external type record.

    • Data string - The data content for this record. This is saved without any encoding done by Kalipso. Encode with StringToUTF8() for example if you need to pass Unicode text, or other type of encoding.

    • ID string (optional) The ID of the record.

NFC uses NDEF messages to transmit information/data. An NDEF message is composed of one or more NDEF records. You can use this action to create an NDEF message without having to manually implement the NDEF message format, but you can manually build an NDEF message in Kalipso if you want to.

Uniform Resource Identifier (URI) is a string of characters used to identify a resource.
