Where can I find the log of bluetooth enable and disable

**Problem** I have Samsung Note 20 and a Samsung Watch. The watch wakes me up every morning between 4:42 and 4:43 am. This is independent of the time zone. It happens in NZ and Malaysia. It happens even though I have "Do Not Disturb" on a time schedule. I notice that the phone even disconnects from the car, while I am still sitting in the car (with it on). It also disconnects from the car and watch when the phone is showing on an advert on an app. This happens often, maybe it's related to the ad that's being played. **Information** The notification is Phone disconnected. I have this notification on, to remind me if I forget my phone. **Assumption** I assume that bluetooth has been turned off or disabled. **Question** Where can I find the logs on bluetooth enable and disable, so that I can discover what process is responsible?
