@wjcarpenter Standby voltage. the stick doesn't truly power off and there is always a small voltage present in the stick which is why the battery always runs out.
The voltage increasing with a cable plugged in is normal and thank you for pointing out this function.

@kenneth123 Just tried and logged in with no issues.

@Slarck You should always Erase first because of this. never just burn only.
Thats the reason for the big red erase button being there!

@yuyun2000 Did you Erase existing firmware first?

@jbruggem Your first post shows that

1. you haven't configured Arduino to configure code for the M5Stack Core2 which uses a different core and pin config to a base esp32.
2. The example you are using is not an M5Stack demo,
3. Arduino is missing Libraries.

All these errors point back to not have the M5Stack Core2 board type selected.

@Slarck My pleasure.
Alas Last years attempt failed as everyone was too busy and this year I'm in the process of replacing my workshop along with with other sheds But I will announce the 2025 version again in September. on all social media channels this year.

@jeremyn3 You need to follow the instructions on the CoreMP135 product page.

@Boomvalt Xcode is OSX's dev environment and is needed for some low level functions needed for hardware programming even if you are not directly using it.

@KC5JIM Disconnected usually means that UIFLOW2 has lost connection to the server.
Have you erased the old firmware before burning the latest updated version for UIFlow2 for the AWS?

@Boomvalt No must always erase first to remove the previous firmware and config.
Once the erase process is done then you will be asked to bind (you may need to erase the old Atom3 from UIFLOW2 account first) then you can burn a clean update.

@liujinyou Did you burn the correct version of UIFlow for your specific cardputer?
Did you erase the cardputer first before downloading and burning the latest cardputer UIFlow2 version?

@nnazar EZData was only designed for testing MQTT services.
I recommend getting something like the CoreMP135 or the CM4 stack, and building your own private dedicated MQTT server on that.

@gantini The sensor is a capacitive sensor and so the higher the reading the lower the moisture level.
These are superior to the resistive sensors that rot easy but work the same way.

@twigs said in Using M5Stack for Custom Signage Displays – Need Advice:

Hey everyone, I’ve been exploring M5Stack modules for a custom signage controller project—curious if anyone here has experience using UIFlow or MicroPython for real-time display updates?"
"Also open to suggestions on the best units for LED or TFT screen integrations—appreciate any tips!

For a start, Micropython is not a realtime language, it is an interpreted language.

The biggest issue for signage is that of memory and ram, the bigger the sign, the more the memory is required.

@m1cr0lab said in Unable to connect with M5Burner:

@robski @ajb2k3
Thank you for your answers.

I reinstalled M5Burner...

But when I went to the online UIFlow 2.0 application, I realized that, like an idiot, I was using my username instead of my email address to log in.

Now everything works normally. 🙂

Sorry for the blunder... but I'm guessing I'm not the last person this will happen to 😁

Cheers,
Steph

ROFL,
I think most of us have done that at some point!

@m1cr0lab try deleting M5burner and reinstalling, failing that it could be an issue with the server

@zakk3456 doesn’t need to be selected from the device software list?

@Shanks-0
Port B is generally a no as one of the pins is normally input only

@GeorgeR Have you tried emailing M5Stack?

@StefanM5 said in M2StickC Plus2 UIFlow:

Ich konnte UiFlow auf mein M5 brennen und mit M5Burner wird er gefunden. Aber mit UiFlow für Windows 11 sagt er das mein M5 ist nicht online. Wo ist der Fehler ??

Haben Sie sich bei Ihrem Konto angemeldet und das Gerät während des Brennvorgangs an Ihr Konto gebunden?
