Fortunately, USB mode is working for me, so, for now, I'll just use that to play around with my Faces dev kit.

Thanks y'all for the help 🙏🏽

One thing I noticed is that the web IDEs show v1.4.5/v1.4.4 respectively, for CN and SG, but my device is on v1.5.1. Although, I was having this issue with v1.4.5 on the device as well, so maybe that's not the problem.

Is there any other way to debug these kinds of issues?

Was just trying to make sure nothing's wrong with my setup/device etc.

When it fails for me, I just keep trying over and over until it works. Sometimes it takes 3-4 times for me. Also try to hit the refresh button at the bottom left of the UI to see if you get “connected” before uploading your flow to the M5Stack.

@m5stack can someone please comment on the Internet connectivity issue ☝🏼? Is it working for anyone?
Internet access has been working ok for me but I may have been lucky. As there is only one server hosted in china (and one in singapore but we dont know how to switch between them) access can be problematic at certain times of the day as loads of people try to access the server.

Now, I'm able to connect to it from the desktop IDE via USB (when set in USB mode). I had to restart my Mac, though, for things to work.

One problem, however, is that it still doesn't connect to the device in Internet mode, via flow.m5stack.com. After I enter the APIKEY displayed in the device screen, I keep getting the same Upload code failed... error in this mode.

UPDATE 1: Looks like another user, @spoetnic, seems to be reporting a similar issue with the Internet approach (https://forum.m5stack.com/topic/1920/ide-crashes-after-startup-and-webide-cannot-connect-to-device-upload-code-failed-maybe-your-device-is-offline-check-it-and-retry/3), although they're on Windows.

UPDATE 2: So, I updated the firmware to v1.5.1. Still have the same issue. Internet mode refuses to work.

I setup mu-ide and connected to the device in USB mode, got a repl and ran the following commands:

>>> import network

>>> wlan = network.WLAN(network.STA_IF)
I (51991) system_api: Base MAC address is not set, read default base MAC address from BLK0 of EFUSE
I (51991) system_api: Base MAC address is not set, read default base MAC address from BLK0 of EFUSE

>>> wlan.ifconfig()

>>> import urequests
I (431608) modsocket: Initializing

>>> urequests.get('https://www.google.com')
Traceback (most recent call last):

  File "libs/urequests.py", line 117, in get
  File "libs/urequests.py", line 54, in request
IndexError: list index out of range

It's clearly connecting to my WiFi, getting an IP, but unable to make requests.

@lukasmaximus, please help!
