ICODE SLIX2 Commands

ICODE SLIX2 Commands

Sept 18, 2025

The ptxNativeTag_T5T API comes with some basic commands implemented, like read/write/lock single block and multiple blocks. There are many more ICODE SLIX commands however, which are not included in the SDK. There is a non-official example implementation of these commands using the non-OS IOT Reader SDK. The example can easily be applied to the OS and POS SDKs as well.

Example 1

This example supports the following commands:

  • Get Random Number - 0xB2 

  • Set Password - 0xB3 

  • Write Password - 0xB4 

  • Protect Page - 0xB6 

  • Enable Privacy - 0xBA 

  • Read Inventory - 0xA0 

  • Get System Information - 0xAB 

The project is made for the RA2E1 Evaluation Board and the example application includes a command line interface. For this a serial emulator software is required, like Tera Term.

1. Set up the UART pins of the RA2E1 EVB

2. Add SLIX2 DEMO in project setting

3. Set Transmit to CR+LF and enable "Local echo" in Terminal settings of Tera Term

4. Open the emulator and approach a tag to the antenna

5. For Set password (write) settings, enter b3 -> 02 -> password 4byte as shown below (initial value is “0000”)

6. For single block write, enter 21 -> block number to change value -> data to enter (4byte) in that order

Command Examples with SPI MOSI:

 

This approach is more integrated, it involves making changes to the ptxNativeTag_T5TSetCommandHeader()  function in ptxNativeTag_T5T.c  and to the ptxNativeTag_T5T_t  structure in ptxNativeTag_T5T.h .

Example 2

This example contains only 3 commands (Get Random Number, Set Password and Protect Page) and the project uses the SDK's RA4M2 reference implementation (EK-RA4M2 Evaluation Board). This approach involves no changes to core SDK functions or structures. The example application executes the commands in order once a T5T tag is activated, then exits the application loop. Output is printed to UART (pin 112 TX, pin 113 RX). Command parameters can be changed in ptx_IOT_RD_Main.c .

Get Random Number command using UID:

Random number received: 0x3F61

Set Password command using UID:

  • Flags: 0x22 (Address Mode, High Data Rate)

  • Command: 0xB3

  • IC Mfg code: 0x04

  • UID: 0xE0040150D7BA5662

  • Password identifier: 0x01 (Read)

  • XOR password calculated from random number and password: 0x3E613E61

Protect Page command using UID:

  • Flags: 0x22 (Address Mode, High Data Rate)

  • Command: 0xB6

  • IC Mfg code: 0x04

  • UID: 0xE0040150D7BA5662

  • Protection pointer address: 0x14

  • Extended protection status: 0x01 (page L is read protected)
