code to read and write NDEF on X-NUCLEO-NFC07A1

[Schuyler]

Can the following code be used to enable the phone to read and write NDEF messages?

I use X-NUCLEO-NFC07A1 and NUCLEO-L476RG

Hi,

calling NDEF_WriteNDEF or NDEF_ReadNDEF before the various initialization cannot work.

I would suggest to have a look to MX_NFC7_Init and to customize it to fit with your needs.

Hi,

I know what you mean and I've been to see it. If I insert NDEF_WriteNDEFand NDEF_ReadNDEF after MX_NFC7_Init such as between/* USER CODE BEGIN 2 */ and /* USER CODE END 2 */, Can I enable the phone to read and write NDEF messages?
