How to use Fitrockr Live Streaming

Set up user

Each Garmin device that should be live streamed requires a user in Fitrockr.

To set up a user, go to the Fitrockr Control Center (Web App) and select Users from the left-side navigation.

Create user. If user details (e.g. height, weight, etc.) are unknown, use average dummy values. 

After user account is created, select the user and click on the QR-Code icon.

Start live streaming

(1) Download the “Fitrockr Live” app from the Play Store onto an Android smartphone or Android tablet.  

(2) Start the Fitrockr Live app and scan the QR Code of the user that should be associated with the Garmin device.

(3) Pair the Garmin device. 

(4) After pairing, the Garmin device will immediately start live-streaming its data to the Fitrockr Live app. By default, data is not sent to the Fitrockr server.

(5) Click on “Sending” to start data transmission to the Fitrockr server. This will make the data stream accessible in the Fitrockr Control Center (Web App) as well as via the Fitrockr API.  

Fitrockr Live app will continue to stream data even if the app is minimised or completely closed.  

The app requires an active Bluetooth connection to stream data. If Bluetooth connection breaks up, data stream will stop and automatically reestablished once the Bluetooth connection is active again.

If you want to view the live data stream in the Fitrockr Control Center, follow below steps:

(1) Go to the Fitrockr Control Center

(2) Enter your login and password

(3) Navigate to Live > Dashboard

(4) Click on “Select a track” (make sure that your data stream is set to “Sending” in der Fitrockr Live app)

(5) Data stream appears in the browser. 

(6) Click record if live stream data should be saved.

A recorded live data stream can be downloaded and its data analysed. The live data stream is not saved to the database as raw data elements. This means that the data cannot be analysed in Reports and Exports like data synchronized via the Fitrockr Hub app.
