Currently I do have a working X-NUCLEO-NFC03A1 demo board connected to a microcontrollerm, using the ST NFC libarary here https://github.com/stm32duino/X-NUCLEO-NFC03A1
I can read and write a NFC Type 2 tag without any problems.
Now I'm trying to get it to work to detect an Android device (Nexus 5X) in host-based card emulation mode (HCE details here https://developer.android.com/guide/topics/connectivity/nfc/hce#java - it should emulate a type 4A tag).
But I'm not even able to receive a response to the REQA command send by the ISO14443A_REQA() function from the library, when scanning for NFC Type 4A Tags!
Do I have to change something in the library to get it to work with an Android device?
I also tried the WUPA (0x52) command instead of REQA but same result.
