I have an app using ACR122U and NTAG203. I have no problem to read or write NDEF messages with ACR122U.
My clients are expanding and I'd like to change all platforms to use Prox-SU.
I acquired a Prox-SU to test. Almost all works well except when reading NTAG203.
With NTAG203, the Prox-SU is identifing my tag as MIFARE Ultralight. So, I am able to read only until page (block) 0x0F according to documentation of Prox-SU. But I have data saved above of page 0x0F because my tag is really a NTAG203 (41 pages in total).
When I use ACR122U reader, I have no problem to read or write to this tag and I can read beyond page 0x0F.
I have been searching for support, but it has been too hard to find technical support from Gemalto.
Is it possible to use NTAG203 with Prox-SU to read pages above 0x0F?
