Hello @huanfai

looking at the soucre code for UIFlow2 device firmware I think authentication keys are fixed to default values. See here and here.

In ohter words I don't think the RFID blocks in UIFlow2 can handle anything different than default authentication keys.

Thanks
Felix

I got it!!

Sorry, the trouble was very simple!... If you want, the solution is below:

@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!

Hello @oracle_sod

ok, I see, the DFRobot version has an UART interface. M5ExtIO2 GPIOs can be set to multiple modes (input, output, ADC, servo, neopixel and PWM) but I am afraid none of these modes can be used for an UART connection.

According to the wiki page RX is used to select the mode, this could be achieved via M5ExtIO GPIO set as output.

However the TX line sends data with 9600 Baud, which I doubt M5ExtIO2 can handle.

That said, what is the reason you don't connect all three Ultrasound units directly to the M5Core? That would require 6 GPIOs.

And if you could live with the fact that all three Ultrasound units use the same mode you could get away with only 4 GPIOs, 1 GPIO to select the mode for all three units, and 1 GPIO for each unit to receive the UART data.

Thanks
Felix

@felmue Hello , Your code worked perfectly. I really appreciate the time and effort you put into helping me—it means a lot! Thank you!

@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?

UIFlow2 is good, but lots of old devices isn't supported. Even in UIFlow1, some devices still can't be used. I don't know why.

@NiktoI you need to use m5burner to erase the firmware to burn new firmware.
You also need to put the cardputer into firmware mode.

@Paulskpt I remember I had similar with CoreMP135 when uiflow2 firmware was loaded in to it, it won't display email and account status on display but..but it was connected and visible as online in web uiflow2 in device list

@oracle_sod and your code is.....

@felmue

Thanks Felix. I've added the same delay as in your code and that has fixed my issue. I still have an error in the terminal if I have it connected to my PC but at least the app is functioning now and I can restart my M5 Paper straight into the app.

Thanks very much for your help.

In most programming languages, you can print strings on new lines using escape sequences or built-in functions. In Python, use \n like print("Hello\nWorld"). In JavaScript, console.log("Hello\nWorld") works. Some languages support multiple arguments, like print("Hello", "World", sep="\n") in Python. This method ensures cleaner and structured output.

@ajb2k3 said in NTP in UIFLOW2?:

@kuriko UIFlow2 has blocks available for UTP control but as UIFlow is built on micropython, NTP is available in the background code functions.

Any possibility giving me some guidelines how to do this?

Public Profiles: Visible to all users, allowing others to see your projects, contributions, and activity. Great for networking and showcasing work.

Private Profiles: Restricted visibility, keeping your projects and activity hidden unless shared directly. Ideal for personal or confidential work.

@PaulSchulz Same here, maybe they forgot or a workaround can be to get rtc time and add 30 min to display correct time, hope its updated soon
