ST25DV16 reading issue

[plawat]

We programmed the ST25DV16 tag using the antenna and the GUI using the ST25R3919B. However, when we use the android apps to read the ST25DV16 tag its not getting read. The android apps read all the other tags of 13.56 mHz available in the market, but not ST25DV16 tag.

We are also able to charge the small battery of 24mAh connected to the ST25DV16 tag using the ST25R3919B as poller.

This tag is read using the GUI and the EVK of ST. How to make it work and be read by the android phone?

Hello, 

Can you please give some precisions on "The android apps read all the other tags of 13.56 mHz available in the market, but not ST25DV16 tag."?

- Does the application report the presence of the tag?

- What do you do to try to read the tag in the app?

- What is the content of the tag's memory ? (is there a NDEF? What is the CC File value ?)

- What version of Android are you using ?

Best regards.
