Trouble Writing NDEF Text via I2C on B-L475E-IOT01A2 (M24SR64-Y)

Hello everyone,

I have the B-L475E-IOT01A2 board equipped with the M24SR64-Y, connected on the I2C2 bus. I managed to write URI, SMS, and email records, and even successfully wrote NDEF text via a mobile application. However, I haven't been able to write NDEF text via I2C.

Is there any guide or example available that could help me resolve this issue?

Thanks in advance for your help!

Hello,

You might want to refer to the following application note that gives recommendation on how to write to M24SR based on the I2C interface

AN4420_Rev1.book

and specifically, Appendix C
