Mate I think you are overcomplicating this something fierce. It runs in the background. It logs all encounters by either advertising its presence (Peripheral mode) or scanning for devices (Central Mode). They alternate between these states. When two devices encounters it's logged on both sides. That device is blacklisted for a few cycles to avoid constantly logging it. The 15 minutes 1.5m conditions are applied on the reporting side after it is uploaded. No conscious effort. Kinda like how your email client pings you when you receive an email. When was the last time you had to consciously think for an email to come into your mailbox?
