Demoapp from libnfc-nci does not detect NFC tags with PN7160

[lukas-janik]

Hello,

I'm adding NFC functionality to our product. I'm using NFC2 CLick dev board which has PN7160 on it. [https://www.mikroe.com/nfc-2-click](https://www.mikroe.com/nfc-2-click) .

It is connected using I2C to our ARM SoC. I have built the libnfc-nci repo, branch **NCI2.0_PN7160** with modified GPIO number and I2C dev path macros so that it matches our setup.

I have also enabled debug prints and set correct NXP_TRANSPORT in the libnfc-nxp.conf.

Now, when running the nfcDemoApp poll, it seems that it communicates and basically everything goes OK - on the first run the FW even got updated. The thing is, that no tag is detected. I have tried with attached Type A tag (which my cell phone recognizes).
Excluding changes mentioned above, configuration files are in default state.

What could be the reason? Do I need to tweak RF parameters in the configuration or should it work out of the box?

Thank you in advance,
Lukas

@Tomas_Parizek found a problem with my NXP_EXT_TVDD_CFG_2 configuration in libnfc-nxp.conf.

The value of 9th configuration byte (the byte before the last byte in the configuration array) needs to be set to `0x10` when operating at 3.3V. Both factory test app and nfcDemoApp now works as expected.

NXP_EXT_TVDD_CFG_2={20, 02, 0F, 01, A0, 0E, 0B, 11, 01, C2, B2, 00, B2, 1E, 1F, 00, 10, 0C}

Thank you!

Hello @lukas-janik , 

I see you are using a 3.3V supply as the transmitter power source, right? Could you please check the following settings? 

The RF activation could be "blocked" due to the TXLDO check feature (TXLDO is expecting a 5V supply, but you use 3.3V). 

Please let us know whether this helps.

Hello Tomas,

thanks a lot. Yes, We're using 3.3V supply; the NXP_EXT_TVDD_CFG was set to 0x02.

Will let you know as soon as I'm near the HW.

[Tomas_Parizek]

Hello @lukas-janik , 

Ok understood! 

Please check byte number 9  in the NXP_EXT_TVDD_CFG config. 

For a 3.3V supply, this bit shall be set to 0x10

Unfortunately, changing the 9th byte did not make a change. I have checked the nfcDemoApp output to see that the value really changed to 0x10 but it still does not recognize the tag.

I have also tried to replace the OM27160A1 board with another one to check for HW issue but it behaves the same.

I tried to compare communication pattern of the demo app running on the LPC824 vs nfcDemoApp running on the RPi and noticed that there is broader set of technologies enabled on the nfcDemoApp.  But when I change any of POLLING_TECH_MASK, HOST_LISTEN_TECH_MASK or P2P_LISTEN_TECH_MASK in the libnfc-nci.conf, the communication dump is the same so I suppose that the file is not used.

Following is the communication dump after changing EXT_TVDD_CONFIG:

We can see that you have enabled all polling technologies, including the proprietary ones and those reserved for future use (RFU). 

Can you please keep only Type A enabled and try it out? This can be done in the libnfc-nci.conf. 

Once you change the settings in the libnfc-nci.conf, you need to "push" this file into NFC Controller (PN7160). 

[lukas-janik]

Hello,

thank you for such a deep investigation. In fact reducing technologies is one of first things that I have tried but thought that the libnfc-nci.conf is taken into account for every operation with libnfc-nci library.

Can I push the configuration using nfcDemoApp or do I need some special tool?

[Fabian_R]

Hello sir,

There is no need to use any special tool. The DemoApp you are using is the following project: GitHub - NXPNFCLinux/linux_libnfc-nci: Linux NFC stack for NCI based NXP NFC Controllers

Inside the directory conf, you will find the libnfc-nci.conf file.

In PN7160 Linux porting guide

section 5.1 Installation instructions you will see the steps to rebuild the project with your new configurations.

Hope this information may have been useful

[lukas-janik]

Hello Fabian,

the root cause of the problem with libnfc-nci.conf was, that the GetNumValue() parser from libnfc-nci silently ignored HOST_LISTEN_TECH_MASK, POLLING_TECH_MASK and P2P_LISTEN_TECH_MASK. All these remained default, which is the full technology scope, including proprietary technologies.

The app now continues further, but still not quite where I wanted to be:

These are last lines of the communication dump with updated technology settings:

I have set all the HOST_LISTEN_TECH_MASK, POLLING_TECH_MASK and P2P_LISTEN_TECH_MASK to 0x01.

In 2103050200018001 It can be seen, that there are only 2 technologies selected - NFC_A_PASSIVE_POLL_MODE and NFC_A_PASSIVE_LISTEN_MODE.

Followed by response 41030100 which should mean NCI_STATUS_OK.

The demoApp then sends RF_DISCOVER_MAP_CMD with 0 mapping configurations and aborts.

Right now I'm investigating whether this is caused by some mis-configuration, or a bug in the nfcDemoApp.

[Fabian_R]

Hello sir,

Thank you for letting us know of this issue. I will share this with the respective team.

This is correct, you are setting core set config with 2103050200018001 correctly.

In UM11495, section 10.1.1 RF Discovery State Machine after every RF SET state, it is sending a RF DEACTIVATE CMD in order to start a new state.

Please keep in mind that the demo is only showing it's features.

Would you mind sharing if the tag has been detected yet?

[lukas-janik]

Hello Fabian,

the tag still was not detected, the application Aborts right after sending the DEACTIVATE CMD.

[lukas-janik]

The default value for both NXP_EXT_TVDD_CFG_1 and NXP_EXT_TVDD_CFG_2 byte #9 is 0x01 so I suppose this is most probably the issue

Not sure if I manage to test it on the HW today, but it sounds very promising. Thank you!

[Fabian_R]

Hello sir,

Thank you very much for contacting us.

Regarding this issue. I believe you should not need any additional adjustments since the SPI example doesn't mentions it requires additional RF settings.

Since PN7160 is a controller that doesn’t allow any SW internal changes, the Reader should correctly detect and communicate with the Reader. Also, since this is an evaluation board's RF settings sent should be correctly configured for the practical demonstration. Have you contacted MikroE for this?

Please keep in mind that our support is limited to our NXP Evaluation Kit.

[lukas-janik]

Hello Fabian, thank you for prompt response.

I have also tried with OM27160A1HN EVK with same results. 

Is there anything that I could check? VDD and VBAT is both connected to 3V3 supply. I tried to change NXP_EXT_TVDD_CFG to 0x1 but nothing changed.

[Fabian_R]

Hello sir,

We do provide the examples for a list of MCUs and MPUs from NXP unfortunately, the support for non-NXP hosts is limited. Could you please clarify that you are receiving the expected responses from the PN7160.

In UM11495, section 8.4 Whole sequence to prepare the PN7160 operation. There is a Figure where is shown the Initialization sequence.

Please share the logs with our evaluation kit please.

[lukas-janik]

Hello Fabian,

I'm not sure if I understand the first paragraph - my host MPU is RPi CM4, it is connected to the PN7160 EVK via standard I2C@400 kHz and GPIO pins. Based on nfcDemoApp verbose output and capture from logic analyzer I suppose that the communication is OK.

I haven't found section 8.4 in UM11495 https://www.nxp.com/docs/en/user-manual/UM11495.pdf . Which Figure do you mean?

Logs with log level 0x3 are attached below.

Thank you,
Lukas

[Fabian_R]

Hello sir,

Yes, I believe from the I2C layer, the connection doesn't show any errors.

I'm not sure if you have, but as mentioned in section 8.2 of PN7160 Linux porting guide you could run the NFC Factory test app, you could test if you can turn on the RF.

Also, in section 5.3 Configuration files from PN7160 Linux porting guide there are a number of log levels to be configured.

Sorry, from the User Manual I was referring to section 6.3 Whole sequence to prepare the PN7160 operation as you can see from your log you do get some of the command responses but, is possible that there is an issue with your porting possibly the transport layer driver isn't correctly interfacing with the TL firmware. By running the Factory test app will give us a better idea of where the problem is.

[lukas-janik]

Hello Fabian and sorry for the late reply.
