Can Bluetooth Preferences keep a Mac awake?

It would appear that corrupted Bluetooth preferences may be responsible for keeping a Mac in a constant state of insomnia.

Adrian Mace ( discovered that his 13" M2 MacBook Pro was suffering from excessive insomnia, where it would continually wake every 6 seconds for 6 seconds. The reason given is "SMC.OutboxNotEmpty smc.70070000 wifibt bluetooth-pcie/" which I believe to be "Bluetooth".

Adrian uses a bunch of Bluetooth devices, but typically if these cause a wake, they cause a full wake, not an Insomnia wake. So Adrian did some research and found an article on "Tom's Guide" for resetting the Bluetooth Preferences

After which Adrian's Mac has been sleeping a lot better.
