card emulation with PN7150

Tadashi_1 — Wed, 06 Nov 2024 08:17:49 GMT

Hello,

I would like to implement card emulation using the PN7150.

Since we are programming without an OS like Linux on the microcontroller,

we are directly sending NCI commands from the microcontroller to the PN7150 without using an API.

Commands sent:

CORE_RESET_CMD

CORE_INIT_CMD

RF_DISCOVER_MAP_CMD

Only the following payload is set:

04: PROTOCOL_ISO_DEP

03: RF protocol is mapped to both Listen and Poll for RF interface.

02: ISO-DEP RF Interface

STATUS_OK is returned.

CORE_SET_CONFIG_CMD

The following parameters are set in the payload:

{30, 01, 01} = {LA_BIT_FRAME_SDD, L=1 byte, Param=01}

{31, 01, 03} = {LA_PLATFORM_CONFIG, L=1 byte, Param=03}

{32, 01, 20} = {LA_SEL_INFO, L=1 byte, Param=20}

{33, 04, 01, 02, 03, 04} = {LA_NFCID1, L=4 bytes, "01, 02, 03, 04"}

STATUS_OK is returned.

RF_DISCOVER_CMD

The following parameters are set in the payload:

0x01, 0x80, 0x01

Using 0x80, NFC_A_PASSIVE_LISTEN_MODE is requested.

After these command communications, when I bring a smartphone running the TagInfo app close, an RF_FIELD_INFO_NTF(0x01) is received, but immediately after that, an RF_FIELD_INFO_NTF(0x00) is received.

According to an RF checker, the signal seems to be emitted.

Afterward, RF_INTF_ACTIVATED_NTF does not arrive.

From these observations, it appears that card emulation is not being activated.

Could anyone please help me understand what might be causing the card emulation to fail to activate?

Hello sir,

We don't recommend the use of PN7150 for new designs, if you are in an early stage of development please explore the possibility of using PN7160 for a new design since, the support for PN7150 is very limited.

Regarding your issue, have you tried our PN7150 example (SW4325) this is an example that provides the possibility of emulate a T4T and, can be read by the TagInfo App.

For further information please take a look at AN11990

Hello Sir,

Thank you for your response.
Then I will consider using the PN7160.
Could you please provide the datasheet and sample code for the PN7160 to replace the PN7150's AN11990 and sample code?
Additionally, although I assume it may be mentioned in the datasheet, could you let me know the most recommended combination of microcontroller board and NFC controller board?

Best Regards,

Tadashi

Hello sir,

The application note for running the software can be found in the following link:

I can also be found in the PN7160 link, scrolling down to the Documentation section and looking for AN13288

The software can be found in the PN710 site but, in the Software section as SW6705

The recommended MCUs are mentioned in AN13288 but they are: LPC82x, LPC55S6x and i.MX RT1170.

Hello,

Based on AN13288, I have purchased the following items:

- OM13071 LPCXpresso824-MAX board
- NFC controller board (OM27160A1HN)
- Arduino interface board (OM29110ARD-B)

Following the instructions in Section 2.1 (LPC82x) of AN13288, I completed the hardware setup, ensuring the above three components are correctly connected.

As per Section 3 (SW setup), I installed MCUXpresso IDE and imported the project.

Following the instructions, "Click on the 'dark blue bug' icon to build the project," I selected NXP-NCI2.0_LCP82x_examples<RWandCE_Debug> in the Project Explorer and clicked on the dark blue bug icon.

However, the following Error(A) appeared below.
Then appeard Error(B).

What steps should I take to resolve these errors (A) and (B), to successfully build the project to start debugging?

Hello,

Could you please clarify that you have installed the LPC82x SDK? This has to be downloaded in the following site: https://mcuxpresso.nxp.com/en/select by searching the board's name: LPCXpresso824MAX

The full guide is in the following link: https://www.nxp.com/webapp/Download?colCode=UM10830

My recommendation would be to please test the board by flashing one of the examples from the SDK and then, follow AN13288.

In case the issue is still persistent, please make sure you are using the latest MCUXpresso and, NCI-example software version from the PN7160 site.

Dear Fabian,

The issue has been resolved, and it has been confirmed that the evaluation board connects to the PC via VCOM.

It seems that the settings in MCUXpresso IDE were not configured correctly. After tinkering with various options in the Debug Configuration screen, the connection suddenly started working. However, since I was randomly trying different things, I can't pinpoint which specific change fixed the issue.

For now, I have confirmed that the evaluation board operates in card emulation mode. I am currently analyzing the sample code to better understand it so that I can port it to another microcontroller and make it work.

Thank you for your support.

Best Regards

Hello sir,
I would be great to know what might the issue be.
But at least it has been resolved, we will check it also from our side to discard any problems in our configurations and software.
Thank you very much for letting us know this.
