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

press and hold red button then slide it out

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

@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

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

yes Uiflow 2.0 web needs Uiflow 2.0 firmware inside controller.

@markram14

Does UIFLOW supports Modbus TCP - i'm trying to read Modbus device (meter) on my network by using M5GO on wifi?

does your stick loads ok with latest M5Burner firmware? Is user demo from M5Burner works? I can confirm that arduino M5stickCplus2 examples do work as had them in recently. Display, IR, Rtc, Battery, IMU, I've used Arduino 2.3.2, be sure you pick M5Stick Plus2

@csjung74 said in Tab5 screen don't display anything with UiFlow 2.0:

@robski

It is happening on just 2 Tab5s that I bought a week ago.
And I flashed all versions of UiFlow2 firmware onto these 2 devices. But I found the same issue on display of Tab5.
But, If flashing Tab5 User Demo f/w onto these devices, then these devices are displaying normally.

But, It isn't happening on the Tab5 that I bought about 2 month ago.
(Of course I used same f/w version and flashing method.)

so you have 3 Tab5s all 3 with same uiflow2 version burned in via M5Burner and then loading same project to all 3 Tab5s 1 is ok (oldest) and 2 are behiving bad . But then also all 3 Tab5s are ok with M5 demo project

from M5Docs:
ENV Pro Unit is an environmental sensor that utilizes the BME688 sensor solution, supporting the measurement of various environmental parameters such as
volatile organic compounds (VOCs),
indoor air quality (IAQ),
temperature, humidity,
and atmospheric pressure.

in simple terms you can't mix diff types(colours) of connectors on same device port,

Run - doesn't flash your code to device memory - also uses wifi settings made in M5burner
Download - flashes your code so it is in device after reboot - if you need wifi then such blocks must be in the code too as device will not be visible for uiflow2 after reboot without wifi blocks

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
