I missed "android:digits" before, now it worked.Maybe you missed a necessary attribute either.
This is my code:
<com.alimuzaffar.lib.pin.PinEntryEditText
android:id="@+id/code_edit"
style="@style/Roboto_Regular_18_black"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="24dp"
android:cursorVisible="false"
android:digits="0123456789ABCDEF"
android:inputType="text"
android:maxLength="6"
android:textIsSelectable="false"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="@id/promt"
app:pinBackgroundDrawable="@drawable/pin_background"
app:pinBackgroundIsSquare="true" />
