Kalipso - Form - Actions - Actions Description - Group RFID - NFC Tag Send Command

Uses the device NFC antenna for sending a command and receiving the answer to HF tags when in close proximity.

Action available for the following operating systems:

Parameters

• Tag Type numeric - The type of tags to write data. It can be one of:

  • 1 - Mifare Classic

  • 2 - Mifare Ultralight

  • 3 - ISO 15693

• Coded numeric - Specifies if the data to write and answer received are coded with ASCII codes enclosed in ‘<’ and ‘>’. This is useful for debugging. It can be one of:

  • 1 - Yes

  • 2 - No

• Command string - The command to send to the tag.

• Target Answer string - The target control or variable to store the command answer.

This action is currently only supported on Android.

A part of Android documentation on the command parameter states:

• Applications must not append the EoD (CRC) to the payload, it will be automatically calculated.

• Applications must only send commands that are complete bytes, for example a SENS_REQ is not possible (these are used to manage tag polling and initialization).

On Android, specifying Tag Type = 0 allows to send a command for any tag type supported by Android.
