Which app version are you using? Is it iOS or Android?
When you go into the lock settings page, “auto-lock, alarm settings and volume” will be greyed out, this means bluetooth is not connected. Once the settings are enabled, it means your bluetooth is connected.
Once bluetooth is connected, you can calibrate the door.
By the way, we are working a test Wyze Lock firmware that will try to resolve some user’s constant recalibration issue. I will reach out when I have more information.
