How do I test my NT3H1101 pass-through mode?

Hi, everbody, I'm York,engineer from Taiwan.

We'are designing a NFC module, choose MCU as Rensas RL78,
and connect to NT3H1101 supplied by Taiwan Woodstone Technologies Inc.
Now MCU is able to communicate with NT3H1101 either Read/Write by I2C.

And cell phone with NFC can read the value I write in from NT3H1101.
Then we want to use pass-through mode, and get problem.

We can adjust the NC_REG, FD_ON, FD_OFF, SRAM Read/Write,
but we don't know how to make a RF testing tool to test pass-through mode with MCU.
Agency in Taiwan said Android APP: NTAG I2C Demoboard has pass-through function for test.
but I can't figure out how this APP to use, then I google it,
and...there's a demoboard for APP to use?

Is APP: NTAG I2C Demoboard, can used for testing pass-through mode
to my MCU, without Demoboards for NFC connected tag chips by NXP? Including Transfer/Receiver.

And How do I control it?
If not, how do I make RF's transferring/receiving to test pass-through mode with MCU?

Many problem, look forward to your reply.

嗨,大家好,我是台灣的工程師,York:

我們在設計一款NFC模組,MCU選擇了Rensas RL78,

然後與台灣宏友科技股份有限公司提供的NT3H1101模組連接,

目前可以由MCU用I2C與NT3H1101溝通了,讀寫都可以,
有NFC手機也能從NT3H1101中讀到我寫入的值。

接著我們想研究pass-through mode,卻遇到了問題。

我們可以調整NT3H1101的NC_REG、FD_ON、FD_OFF,也可以讀寫SRAM,

但我們不知道怎麼控制RF端的pass-through mode 測試。

台灣代理商說下載Android的APP:NTAG I2C Demoboard 裡面有pass-through功能,
但我不太能理解這個APP如何使用,並且上網查循,
這個APP似乎還要跟Demoboards for NFC一起使用?

請問APP:NTAG I2C Demoboard能在我沒有使用Demoboard、只使用自己的MCU下,
測試pass-through mode嗎?包括送與收。
而我要如何控制呢?
如果不行的話,我該怎麼製造RF端的收送,來測試我的pass-through mode呢?

以上問題,盼求解答。

徬徨的 York

Maybe a bit late for your project right now, but for everyone else looking for the same answer:

To test Pass Through mode you need to read from NFC on the SRAM address, not the EEPROM NDEF area. Most Apps out there only read & write standard NDEF in the EEPROM area.

I use the Android APP "NFC Tools", go to tab "OTHER" and select "Advanced NFC commands".

Here you can specify the ISO standard and enter any NFC command + parameters in HEX. The app will calculate the CRC when sending. So to read the pass through area you simply use the READ command and specify the SRAM block address such as: 30h FCh to read the last 16 bytes in the SRAM (block FCh).

Hello,

The demo board is the following: OM5569-NT322E | NTAG I2C plus Explorer Kit | NFC | NXP 

There is also source code for the mcu implemented in this explorer kit which might help you to take it as a reference for your custom implementation. For this, please refer to the board's firmware source files available in the documents and software tab.

Hope that helps!

BR,

Ivan.
