Hi all
I'm trying to use the NT3H2211 to write a dynamic UUID to the EEPROM of the NT3H2211 using an Arduino so that it can be read over NFC using a smartphone. Somehow whenever I communicate with the NT3H over i2c the NFC stops working. The NTAG i2c Demo reports the memory as "Locked" and TagWriter also returns an error. As soon as I stop communicating over i2c and restart the device I can read the (unchanged) content again.
Is there any documentation or example code that could help me implement my use case? What I want to do is write a simple NDEF record to the NFC chip over I2C using an Arduino. I have already tried using a library like GitHub - ameltech/sme-nt3h1x01-library: Library for SmartEverything NT3H1X01 Near Field Communicatio... but only the device id reading worked. I had no success writing an NDEF record.
Thanks for your help!
Best regards
Max
Hello,
We do not have an arduino example, nonetheless,s you can use one of available examples with the NXP's MCUs as a base for your development.
Could you please check this post ? There you will find the instructions of how to get the examples for our SDKs
Hope this helps
