<![CDATA[Offline mode in UIflow (StickC Plus2)]]>I'm new into M5Stack world.
I received the stick with a demo program. So I used M5burner to install UIflow. My first surprise was that M5burner decided to use WiFi instead of ttyACM0 to download the firmware.
Once completed, I used Configure to set StartMode to USB.
I downloaded UIflow-IDE and installed it on Linux host.
I boot the stick and set mode to USB and then I start IUflow-IDE. The status bar display "ttyACM0". After a few seconds the status bar display "Disconnected" in red and a message box show: "Upload code failed, maybe your device is offline ...".

Sometimes, on the console, I see:
"[Error: Error Ressource temporarily unavailable. Cannot lock port]
I checked and I have the appropriate privileges to use (r/w) the serial port.

Questions:

'offline' in the messageBox. What does it refer to?
Is it possible to use UIflow with WiFi?
How can I fix my problem?

Thanks for any help
