PN7160 interfacing with ESP32 S3 MCU

Chri-sy — Wed, 26 Nov 2025 14:48:57 GMT

I have developed an NFC reader based on the PN7160 and have not been able to progress with the firmware and make it work. I am interfacing it to ESP32 S3 MCU as the host controller. I have been using the attached material as reference but with no success:

The code seems to work fine but I could not read an NFC tag despite placing it above the antenna. See attached log

I am writing this to request support on getting the PN7160 to work with ESP32 S3. Thank you

Hello @Chri-sy, Good Day!

Unfortunately matters related to the use of third party hosts and modules are out of our support scope. However, I would suggest taking a look at section 11.2 of the PN7160 Data Sheet to get further details on the functional description of the I2C interface, and ensure a proper addressing of the device is taking place.

You could try basing your implementation on the available "PN7160 NXP-NCI MCUXpresso Example Project" which you can find at the product page. Please refer to the NXP-NCI2.0 MCUXpresso examples guide in which you will find a detailed description on how to use the examples with tools like MCUXpresso IDE , but it could be a good starting point.

I would also suggest referring to the manufacturer of the module to see if there is any software example available for the device.

My best regards,
Daniel
