<![CDATA[CoreS3 not working with UiFlow]]>Since Alpha update 20 Ive not been able to upload a UiFlow sketch.
The CoreS3 button is permanently Red to the left of the Run button.
I also tried the Burn button and that keeps timing out.

I hadn't seen IAMLIUBO's comment about USB mode until after I posted this comment. I am able to connect to my Atom and download programs now through the terminal.

I'm running UIFlow Alpha 22 and also was able to burn that firmware to my Atom. Am I to understand that this is paper weight until this is resolved? I'm in the US.

We have done some tests, found that in Europe may have network connection problems, because we do not currently deployed servers in Europe, we will make improvements in the near future, for the time being you can use USB mode for development, you can watch this video: link

I had email contact with M5stack and they recommended using the webburner. Not sure if that is the reason it works now, but I can program the device wireless from Uiflow2 with no problems. CoreS3 and Uiflow2 seem to work in the Nordic countries now.

Can we get some timeline for when this connectivity issue will be resolved for those of us not fortunate enough to live in China? At the moment the cores3 is a very beautiful looking paperweight on my desk, it has no use at all without UIFlow2.0 working.

With the crazy geopolitics we have these days, relying on a connection to a server in China to program your microcontroller sounds potentially a little too risky for my liking, I'm sure other companies in the West would feel the same.

There is light at the end of the tunnel in that a device may be coming which will host a private offline server

Ive never used it. There are only two choices listed, as far as I remember.

Or run servers in different locations so people have a choice?

I assumed I was an idiot and did not know how to use UIFlow 2.0. Turns out it was was a server issue all along. The error messaging needs to be improved so first-timers know if they are doing something wrong or there are server issues.

Why does M5stack need to have a device registered on a far away server, just to program it for personal use?

Why isnt there a simple "use it without registering it internationally" mode? I cant think of any other hobbyist platform - Rapberry Pi, Feather, Microbit, Arduino, Beaglebone, Lilypad, Circuit Python, Fez/Gadgeteer, TI-Launchpad, Teensy, NXP-LPCXpresso, Arm-MBed, Parallax, ST-Nucleo, WIO, XIAO, Particle, Sparkfun-Thing - that has that requirement.

Is there a reason?

Thanks I tried that still no success.
Every time I try download a program a Loading... popup message appears in the top right of the screen
Then a message either Execute Program Failed (from the Run button)
or Download Program Failed (from the Download button)
I can flash the demo software no problem.
I can flash the UiFlow from the burner app
and I get the uiflow menu
I cant download any uiflow program to the device.
I've tried logging out and logging back in
I'm just trying to save a simple ui with the background set to blue.
Every time I tried to download the uiflow program it gives the same timeout message.
I've tried holding the bottom button down until the green light comes on.
And saving first before sending.
I think its the fact the red button to the left of Run is never being changed from Red unless I logout then it says select device.
When I log back in and choose the device it goes to red again.

This all happened when uiflow 19 was updated.
Ive tried installing 19 again, and 20 and 21 but still not working.
Ive tried erasing the flash from uiflow and from burner.

Its really frustrating.

Hi, sorry for this happening, could you tell me your location or country? I think there has some network issuse, we need do some test and check.

Click the red button to open device selector, then click on any devices in there and delete them by clicking on them

Try deleting the coreS3 in UIFlow and then repairing in M5Burner.
