@mehdibh, your topic has been moved to a more suitable location on the forum.
Please edit your post, select all code and click the </> button; Next save the post. That way we don't have to look at byte mac[] but it will be properly rendered as byte mac[].
Please take some time to read How to get the best out of this forum.
I take note
thanks for advising
