How do I create a QR code to configure sync.blue® MOBILE Storage on an iPhone?

1. Generate Access Credentials

1. Create a new connection in the sync.blue® Dashboard. 
2. Select sync.blue® MOBILE Storage as the sync target. 
3. Note the displayed access credentials.

2. Create mobileconfig File

Create a mobileconfig file for iOS (e.g., DEMO.mobileconfig) for the CardDAV configuration and replace the parameters inside (MY-CONTACT-LIST-NAME, MY-MOBILE-STORAGE-API-KEY, MY-MOBILE-STORAGE-PASSWORD) with your own values:

3. Provide the mobileconfig File

Upload the completed .mobileconfig file to a secure web server of your choice so that it can be downloaded by iPhones via a URL such as https://www.mycompany.com/DEMO.mobileconfig.

4. Generate QR Code

Create a QR code using any QR code generator that points to the URL of the .mobileconfig file, for example https://www.mycompany.com/DEMO.mobileconfig.

5. Test Functionality

1. Scan the QR code with the iPhone’s camera app.
2. Open the offered profile installation.
3. Install the profile according to the instructions.
4. Verify that the CardDAV account was successfully set up.
