the current consumption issue of NFC,NCS V3.2.1

[joey]

HI

I previously used the NFC feature in SDK version 3.0.0, which had an abnormal current issue after each trigger. After applying a patch from the forum, this problem was resolved. Now, in the release notes for SDK version 3.2.1, it is stated that this issue has been fixed.

When I tested the record_text example, the NFC current consumption was normal. However, when using the writable_ndef_msg example, I noticed that compared to the patched firmware in version 3.0.0, the NFC responsiveness has decreased—sometimes it fails to wake up, and after waking, abnormal current consumption still occurs. Why is this happening?

Hi

I see you're working on an nRF54L15 PDK v0.8.1. This is a preview DK with an engineering revision of the SoC, so it's not guaranteed that it is working at the level of a finished product. Do you have a v1.x.x version of the DK where you can recreate this as well to confirm this is not just an engineering revision issue? 

Note that I have let the developers know about this, so we will look into this on our end as well. I will keep you updated when I hear back from them.

Best regards,

Simon
