Can you see if the following changes fixes the issue?</p> <p><a href="https://devzone.nordicsemi.com/cfs-file/__key/support-attachments/beef5d1b77644c448dabff31668f3a47-3e531fd6d8a648c09a2b0729c8eaf0d5/hal_5F00_nfc_5F00_t2t.c.diff">devzone.nordicsemi.com/.../hal_5F00_nfc_5F00_t2t.c.diff</a></p> <p>(The same issue is also present for type 4 tags, and the fix is similar in&nbsp;<code>hal_nfc_t4t.c</code> instead).</p><div style="clear:both;"></div>
