NFC HCE - no events at all

Galaxy Watch for Tizen
1

Hi,

In here: Near Field Communication (NFC) | Tizen Docs

There is a mention for HCE (Host-based Card Emulation).

This interests me, however the documentation is far from clear:

I tried to use “nfc_manager_set_hce_event_cb”, but no event is being received at all, when I approach my watch to a NFC-reader device.

Also tried calling “nfc_se_set_preferred_handler”, doesn’t make any change.

I only want to know how can I request my watch to “pretend” it’s a normal card with UID of AA:BB:CC:DD.
How can I do that?

Please help me with this topic. Almost nothing is available online. :frowning:

Hello,
Can you please share the NFC reader details?

I tested it with various readers (ZKTeco QR500), but the easiest is a Galaxy Phone with some application (MIFARE Classic Tool, or TagInfo by NXP).

All reports the UID of the watch, but I can’t figure out on how can I make the watch to report a desired custom UID.

Was this ever resolved?

No. And Tizen watch unfortunately died.

Im on WearOS watches now (Galaxy Watch6) but all watches after Active2 looks dummy. Active2 was best looking watch Samsung ever made.
