Thank you, Christoph. I made a mistake while dividing the patch. I will be careful. I will merge with the code that uses the function and put it on the next patch. And as you mentioned, it is duplicated with the configuration of bio's data payload. I will improve this by reflecting your proposal. Best regards, Jinyoung.
