Hello Sidi,

what software are you using on the CC26X2? Do you have already software that controls the TRF7970A?

Best regards,

Hello Helfried,

I ported the example from MSP432 (TIDM-NFC-RW Software).

Hello SIDI,

The commands to read a Type 2 tag are handled in the t2t_app.c file.

Your tag needs to be NDEF formatted to be read with that software.

You can use a phone app to format your T2T and then try and read it.
