Enabling NFC on SE050ARDF2 board

[Shivangi]

Hello NXP community and support team,

I've been working on porting middleware for the SE050ARDF2 with an STM32 MCU. So far, I've successfully managed to port the middleware, and the "get info" example works perfectly fine. Additionally, I've tested functionalities like writing user IDs and some other functionality.

However, I've hit a roadblock when it comes to enabling NFC detection with the SE050. I'm currently seeking guidance on how to enable NFC in the SE050 and how to perform testing to ensure it's functioning as expected.

I have checked the link given below get the steps for NFC enable in SE050 but not getting clear idea about commands.

Can you please provide step-by-step instructions regarding enabling NFC on the SE050 and conducting relevant tests?

Thank you in advance for your support!

Hi @Kan_Li ,

Thank you for the reply.

Can I use the mobile phone as a NFC reader instead of the one you suggested Identive CLOUD 3700F reader ?

BTW, only 1 interface can be selected to communicate with the host, since you are using SE050F2 with MCU like STM32, I2C interface should be selected by default, so it is not possible to enable the NFC interface at the same time. 

So to enable the NFC, I need to disable the I2C communication from STM32. Is my understanding correct ??
Is there any video or tutorial available to work with NFC ? Can you please share link of the same ?

Thanks,
Shivangi

Hi @Shivangi ,

Yes, NFC mobile phone can also be used for that purpose, but you have to design the app by yourself.

To enable NFC, disable the I2C communication from the host controller is not enough, you have to remove the power as well, and let the RF field from the NFC device to power the SE instead.

Hope that make sense,

Have a great day,
Kan

Hi @Shivangi ,

You may refer to the following for details.

1. Board settings: To configure the SE050ARD board using NFC interface, please refer to 4.4 in https://www.nxp.com/docs/en/application-note/AN12395.pdf .

2 . MW configuration: Please refer to  https://www.nxp.com/docs/en/application-note/AN12398.pdf to set up the MW to work on PC. and please also note to select PCSC as the com port.

Since you are using SE050ARDF2, platformSCP should also be enabled. Please refer to chapter 6 in https://www.nxp.com/docs/en/application-note/AN12398.pdf for details.

3. You have to connect a NFC reader such as Identive CLOUD 3700F reader(https://www.nxp.com/products/rfid-nfc/nfc-hf/connected-nfc-tags/ntag-ic-iplus-i-explorer-kit-with-nf... ) with the PC, and put the SE050ARDF2 board on the reader to run any demo out of the MW.

BTW, only 1 interface can be selected to communicate with the host, since you are using SE050F2 with MCU like STM32, I2C interface should be selected by default, so it is not possible to enable the NFC interface at the same time. 

Hope that makes sense,

Have a great day,
Kan
