@Borja-Blasco Generally it is possible to use the Pins of the camera connector. They are connected to the said Pxx pins. Be aware, that P13-P18 are input-only. Using them as output fails.

Me too, same issue. It is possible that Pycom is not aswering on this??

@mia1913 don’t know the details of the interface / library, but at a low level, 7 and 10-byte UUIDs are actually transmitted in several round trips. For a 7-byte UUID, only 3 bytes of the UUID are returned, and the other byte is a special value which means “there’s more”. You then do another request which returns the remaining 4 bytes. No idea how this is/should be handled on the Pyscan, though.

@rskoniec Yes, I tried it, but it did not work. The type of NFC tage I use is Ntag213.
