You can open the debugger via the debug icon on right side of the view canvas toolbar.

Debugger location

To connect your device with the debugger, open the SAP AppGyver preview app. There, you'll find the toggle switch to connect the debugger. After a few seconds, the connection should be established and you can start debugging your app.


If you are experiencing problems, try connecting both the computer running debugger and the device(s) running the Preview app to the same local network (e.g. same WiFi)!


In the 'Connect' tab you can see all currently connected devices to the debugger. You can choose between those, and view additional identifying information through a drop-down menu.
