PN7642 SDK example Ex8_HCE_T4T does FAILS on iPhone with reader app

ingenutec — Wed, 28 Feb 2024 17:28:09 GMT

I'm using the OM27642EVK and the latest public SDK (2.12.5). I created the HCE_T4T Freertos example in my MCUXpresso workspace.

When I run the example, my iPhone (15 Pro) will read the sample tag when I present it with the home screen visible (background reading). However, if I launch a reader app (e.g. NXP TagInfo) and attempt to read the tag, it never completes.

With Android (Pixel 6a) it works in both background read mode AND foreground read mode (with NXP TagInfo).

Do you have any log file for this issue?

The project itself, unmodified, has no logs. I'll add some...

I can reproduce your issue on my side, it is still under investigation.
