@mearsuit i see this error from some time but projects are working ok

@mnhj have you tried something simple first to start with it ?

@nalom1 this 5v and ground there is to supply sensors/units but voltage levels for gpio are 3.3

press and hold red button then slide it out

@hanktttop said in Cardputer COM Not Working:

@ajb2k3 Yes, I tested the first time this was suggested. In fact, the first cable I was using was just for charging a portable gaming console. Then I tried a few more, inclund cables for smartphones, external drives, etc. And I tested then on their specific devices, everything normal.

No idea why the cheapest one worked on cardputer, though.

I'm glad you have it working now...mark this cable up as Cardputer saver cable

yes Uiflow 2.0 web needs Uiflow 2.0 firmware inside controller.

@spectrad have you tried with the M5Stack example here?

he doesn't have M5Stack controller, only M5Stack sensor trying to read back to Arduino NANO so not esp32 board.

usually when you press "burn" in M5Burner there is red button "erase" thats even without M5 module being detected, before com port selection

@hanktttop said in Cardputer COM Not Working:

New cable, same error. In fact, I just tested it on Fedora 39 (fresh installed), I still haven't been able to put the device in download mode. Maybe I'm forgetting a drive, which makes the device "recognize" the computer as a charger. Still, I reinstalled them all again, with no result.

I have M5Dial with StampS3 at the back...had to remove sticker to see and feel when "boot" button is pressed and hold before usb is plugged in - its almost hard to sense way different from pressing reset button where you can hear click.
With my Dial when say com13 was unresponsive then going in to boot mode made com12 to be available so in short words diff com for programming and different for boot mode - thats my experience with StampS3 from my M5Dial - i had it few times in some unresponsive mode.

is it happening on all 3 all just one?
is it same when fresh firmware loaded too?

you can disable sound and adjust timer, 60s for reset is default it does flash black like many ink displays

general rule for RS485 bus is the same baudrate and parity on all slave devices and each device with different slave ID, max 32 devices on one chain

so You can't log in to old account and unregister device in uiflow2?

I don't think you can bind device in to different account when it's binded already to different account.

Its all based on its MAC address not what firmware or project is loaded to it

@tom-test1 have you tried to use "Thonny" to see and edit files?

see my test on M5Tough with battery

@h12616 you are correct not all M5 devices support M5UI - its not me btw its @kirill271099

@kirill271099 said in ImportError: no module named 'm5ui':

У меня есть проблема, я обновил прошивку на устройстве cardputer, но вылезла ошибка ImportError: no module named 'm5ui', хотя этот модуль используется в документации. В чем может быть проблема?

what firmware ver you updated your cardputer to?

@h12616 - cardputer

@literakl so are you able to display current time and battery level at all...forget about sleep option for now
