How to remote debug a QML application

[themts]

Hi guys,

how can I debug QML on a remote running device?
I tried to use the -qmljsdebugger=port:1234 parameter, but without any luck.
It works as long as I run it on the same machine but how can I connect to remotely running instance?
I don't see any host parameter in qtcreator?

Can someone explain how it works internally?
How does the host (qtcreator) communicate with the application? TCP, UDP ?
