How RAF aerial minelaying was coordinated

When did the RAF begin minelaying, and how was it coordinated with the Royal Navy?

It began near the RAF's creation; Bomber and Coastal commands laid mines and exchanged locations with the Navy, though sometimes belatedly.

The RAF practised aerial minelaying from near its creation. Bomber Command usually handled larger drops, while Coastal Command could send individual aircraft, and both needed to tell the Royal Navy where fields had been laid. In one example, naval and RAF minefields were reported to the other service only days after each had completed its operation. Coordination mattered to friendly navigation as well as offensive effect.
