Thanks for the explanation. It is a pity, when the MCU runs on battery, there is no monitoring that would allow the user to take action when the battery comes close to the threshold value.

After 157 views and No answer, I conclude that nobnody has an answer ;-)... Poor reactivity of this forum ;-(

Core 2 being able to be programmed with UI Flow 1 and UI Flow 2 and as the battery follow up exists in UI Flow2, I conclude that it is missing for now in UI Flow2 and hopefully M5 stack will provide it.

I mean UIFlow 2

Thanks a lot, but as the title indicates is there a battery follow up of Core S3 in UI Flow ?

Hi there

I am starting to experiment with Core S3 . I could not find the Power block available in UI Flow 1 that allows to follow battery remaining capacity, battery voltage and possibly battery current.
The block should be under hardware but there is nothing like that to add.
I am missing something or is this block just not yet implemented ?
Thanks a lot for your comments

You may disregard this post. I changed for another USB cable and was able to recover COM3

Hi there,

I am facing a silly issue. My Core 2 runs a programme that uploads Temp data to a cloud server.
The program runs in autostart mode, after having finalized it in Run mode, I uploaded it.
I would like to burn the firmware again to start a new project

The issue is that the COM port does not show up when I connect the device to my computer.
I suspect that the program is monopolizing the COM port. I have been tryng several attempts : remove the Unit to have the program crash, shut down the program.. No success.

Could you give me advice on how to recover my COM port ?
Thanks for your suggestions

Thanks a lot ! It can be completed and it avoids to start from scratch

Hi everybody,

Is there a table comparing the various products that M5 stack sells.
I only found this web page
https://shop.m5stack.com/blogs/news/m5stack-core-category-overview

but it does not answer my questions, all of the controllers are in the same section and I need to open the details to figure out that M5 core basic has a 150 mAh battery while M5 Core Go has a 500mAh one, that the Core products have the same screen size but non touch version while the Core 2 has a touche screen..
It would be very handy to have all of these features in a unique table..
Maybe it exists but I did not find it. Any sharing on this topic will be appreciated

Hi Adie,

Two comments.
The accuracy of any timer at the 1/100th second level is difficult to assess. You would need a reference timer and connect the start and stop signal both to this timer and to the M5stack /ESP32 based on timer
Absence of a sytem clock. Actually there is one M5 Core 2, its RTC but it reports only seconds, minutes, hours, days.. On the other entry level Core models, there is none but you can add an RTC units that will provide the functionality
