How does the app connect via Bluetooth to the device when out of range?

Here’s how the eSafe app works:

Bluetooth Pairing (Initial Setup): During the initial setup, you’ll need to be within Bluetooth range to pair the app with your key safe. This step establishes the connection between the app and the device.

Accessing the Key Safe Outside Bluetooth Range: After pairing, you can still access your key safe remotely, even when you're outside Bluetooth range. The app allows you to request one-time passcodes or offline codes, which are securely stored within the eSafe itself.

Retrieving and Using the Code: When you're outside Bluetooth range, the app can retrieve the stored code and send it to you. You can then provide this code to anyone who needs to access the eSafe. The user will simply need to manually enter the code into the device to gain access, without needing an active Bluetooth connection. 

In summary, after the initial Bluetooth pairing, the app can still generate and send access codes remotely, making it easy to manage access even when you’re far away.
