Smartphone Sync (single-sync) with Fitrockr Sync app


Setup - Join-Code

Pre-requisite to sync with the Fitrockr Sync app is a Fitrockr user account. Create a user account and generate the personal join-code of the user that should be connected with the Garmin device.

Share join-code with the user to connect smartphone with Garmin device.

(20) sync the Garmin device once before starting data collection. This will apply all necessary configurations to the Garmin device. 

The device is now ready to collect data.

The device will attempt to synchronize automatically in the background.    

Check the settings

Project settings will be transferred to the device whenever it is synchronized. It is recommended to check whether settings got successfully transferred at initial device setup. To do so, check settings in the Fitrockr app under Settings navigation item or in the Fitrockr Control Center under Device when editing a user. 

If device settings are wrong, sync again until device settings have been correctly updated.

Blank out device screen

Project settings allow to blank out device screens. This setting will be transferred during a synchronization. If device screen still allows to swipe through the data after synchronization, restart the app / phone and sync again.

Background synchronization

Garmin devices have a built-in logic when to attempt a background sync. This is event-based rather than time-based. This means that background syncs are happening irregularly. We therefore advise to set up a sync alert to remind users to manually sync if background sync repeatedly fails. 

Set up a sync alert

It is highly recommended to set up a sync alert. In the Fitrockr Control Center, select Manage > Alerts and set up an alert if device is not synced every 2 days. Set up a trigger to send a push notification to participants that fail to do so. This will remind participant to manually sync if background sync was not properly running.
