@digiponta thanks for the update.
I had forgotten that some cards are just not compatible

RE: SOLVED: UIFlow cannot currently connect to any M5Stack devices
@sodar have you tried changing the servers in M5Burner?
There are quite a few people trying to access the same server which means someone will be refused a connection and then there is the Great Firewall of China which sometimes causes problems. -

RE: USB mode on the M5Stack Core S3
@windegg The desktop IDE hasn't been updated in a long time and (from what I was told) will not be updated until UIFlow2 reaches a stable (none Alpha test) version.

UIFl0w2?
You need to log into M5Burner with your forum details and when you erase and burn UIFLOW2 firmware you will be asked to register device to your account -
RE: ATOM S3, How to switch to online programming mode?
By pressing the screen on boot or use M5Burner to get into app mode

RE: USB mode on the M5Stack Core S3
@windegg once you have burned the UIFlow2 firmware, you go into uiflows device selector to connect in USB mode however, usb mode only works with certain web browsers

RE: Transferring files from SD card in UIflow or...
@bergkatse unfortunately no as the limit is actually hardware. The S3 versions may be able to but not the older ones as they don’t have the USB mode architecture

RE: ATOM S3, How to switch to online programming mode?
As far as I am aware, the last program should remain in the memory and switching back to app mode should run it again.

RE: M5Dial mising nfc machine module...
It is possible to add library for the NFC function to the Micropython using a program like thonny.

RE: ATOM S3, How to switch to online programming mode?
There is a button press sequence but the easiest is to use M5Burner and change the configuration to programming mode

RE: Screen turned black
@firoozeh one reason a screen will turn black after uploading code is because your code does not contain graphical elements.
When using M5BURNER you must use the correct firmware for the core.
There are three main cores the core, core2 and coreS3. All three have different firmware and for your unit you must erase and use the Core, Go and fire only firmware -
RE: M5 Stack autostart
As long as there is an active power supply it should auto power on.
As to fonts, there is a memory issue with the core2 which meant that in uiflow1 and micropython a lot of fonts had to be removed as they took up needed space required to support units.
UIFlow2 makes an attempt to fix this issue but isn't fully working yet. -
RE: I want to know the correct procedure for accessing files to SD memory.
All this information is out there and has been online for years however,
Plug in card,
Mount card,
read card,
write card,
unmount card,
remove card
The argument mode points to a string beginning with one of the following
sequences (Additional characters may follow these sequences.):``r'' Open text file for reading. The stream is positioned at the
beginning of the file.``r+'' Open for reading and writing. The stream is positioned at the
beginning of the file.``w'' Truncate file to zero length or create text file for writing.
The stream is positioned at the beginning of the file.``w+'' Open for reading and writing. The file is created if it does not
exist, otherwise it is truncated. The stream is positioned at
the beginning of the file.``a'' Open for writing. The file is created if it does not exist. The
stream is positioned at the end of the file. Subsequent writes
to the file will always end up at the then current end of file,
irrespective of any intervening fseek(3) or similar.``a+'' Open for reading and writing. The file is created if it does not
exist. The stream is positioned at the end of the file. Subse-
quent writes to the file will always end up at the then current
end of file, irrespective of any intervening fseek(3) or similar. -
RE: UIFlow2.0 Cannot install on a Core2 Device
@iot_dev Well done getting it working.

RE: M5Stack Dial Wi-fi Configuration
Is the UIFlow display showing the device connected to the network?

RE: M5Stack Dial Wi-fi Configuration
You can use M5Burner to configure the wifi settings of the dial for default use or configure them in code.

RE: UnitV Can it recognize the type of plant?
As @holofloh has already said.
It should be possible but will depend on the training data you feed to the image recognition model.
In theory the model needs 50+ photos of each plant you want it to recognise in order to build the training model. -
RE: CoreS3 virtual buttons
Sorry, that was a mistake I made on earlier available information. and seamed to work with my fat fingers. I have rechecked, corrected and updated the document and its in the process of being re uploaded.

RE: Image+ problem
It's not freezing, It's just very slow to retrieve the image. I have test (and written a guide on getting the image from the forum) and my experience it that it is very slow to retrieve images, sometimes taking up to several minutes.
Also you haven't specified a wifi network to connect to.
