This way you do not use the local friend code from the UDS library.</p><p>Even on the same device, this data will have a different value every time the application starts, so it cannot be used to identify devices after the application has started. If there is any change to the node ID in UDS communication and DLP communication, the <SPAN class="argument">scrambledLocalFriendCode</SPAN> changes even on the same device.
