Working with NFC tags on MangOH Yellow

mangOH Yellow
1

Hi all,

I am trying to read from to a NFC Tag using the MangOH Yellow. The documentation is limited and I am assuming that only emulate or write capability is currently supported since that is the only one referenced under Observations… it’s called “/NtagDhubIf/writeNDEF” Is this a correct assumption?
The problem is that I cannot get either to work. Please can anyone point me in the right direction. Is the read or write supposed to happen via an observation?
I am using the “NXP MIFARE Ultralight - NTAG215” type tags and is ultimately interested in only reading the tag values.

Thanks
Theo

Hi @theodorjahnke,
It seems to me you are trying the use case of reading from an external ntag. Currently, on mangOH Yellow we have the
https://www.nxp.com/docs/en/data-sheet/NT3H2111_2211.pdf on-board
and the functionality is described in:
https://github.com/mangOH/mangOH/tree/master/apps/ntag.

The NtagDhubIf is used to read/write to the on-board ntag as described there. If you wish to read from an external tag you will need incorporate the NTAG Reader stack vs. the i2c on-board tag stack we used. Let me know if you have any further questions. Hope this helps.
