NRF52832+PN532 NFC Write Tag Function

[Quark]

We are developing a product using NRF52832+PN532 as an external NFC reader/writer over Bluethooth. We have tried the adafruit_tag_reader example on NRF52DK which works well. However, when we try to write an NDEF message to a tag with adafruit_pn532_ndef_uri_tag2_write() or adafruit_pn532_tag2_page_write(), nothing happened. Is there an example for how to use the writing funcitons? Meanwhile, does these writing functions also work on Type4 tag as its name is tag2? Thank you!

Unfortunately I am not aware of any example. The only thing I can say for sure is that t2t write procedures differ from t4t write procedures, so you need to use them properly. Not sure what tag you are using to test on and whether it support writing, for instance out t2t nfc stack does not handle write commands. You should be able to check if tag supports writing by reading its capability container.
