@TimeDelay I did not manage to make the drivers work with my Intel i9 Mac with sequoia. I am using an old intel i7 with Catalina that works fine

How can I monitor the status of the power connection through the pogo pins on the Bottom2 module? Are there any specific methods or code examples for detecting power presence or absence?

M5.Lcd.setCursor(startX, currentY);
float vinVoltage = M5.Axp.GetVinVoltage();
bool hasUsbPower = (vinVoltage > 4.5);
bool hasBackPower = M5.Axp.isCharging(); // Check if charging via any source
M5.Lcd.setTextColor(WHITE);
M5.Lcd.print(F("USB-C: "));
M5.Lcd.setTextColor(hasUsbPower ? PAL_GREEN : RED);
M5.Lcd.printf("%.1fV", vinVoltage);
currentY += lineSpacing;

M5.Lcd.setCursor(startX, currentY);
M5.Lcd.setTextColor(WHITE);
M5.Lcd.print(F("Back: "));
M5.Lcd.setTextColor(hasBackPower ? PAL_GREEN : RED);
if (hasBackPower && !hasUsbPower) { // Only show back power if it's the source
    M5.Lcd.printf("%.1fV", M5.Axp.GetVBusVoltage());
} else {
    M5.Lcd.print(" --");
}
currentY += lineSpacing;

// Check battery level
M5.Lcd.setCursor(startX, currentY);
float batteryLevel = M5.Axp.GetBatteryLevel();
M5.Lcd.setTextColor(WHITE);
M5.Lcd.print(F("Battery: "));
M5.Lcd.setTextColor(batteryLevel > 20 ? PAL_GREEN : RED);
M5.Lcd.printf("%d%%", (int)batteryLevel);
currentY += lineSpacing;

@ioamas
Does anybody knows how to check if the M5core2 is connected to the bottom2 base power with a code?

@teastain
thank you for your answer and concern.
I did open the bottom by removing the circuits screws.
The problem was that on of battery wires was caught between the board and the plastic and was creating the problem. everything now ok!
Thanks everybody for the help

@felmue
you gave me an idea.
I opened it and checked the contacts- on the inside of the bottom2 - they do not contact the pins of the base. also the board seems elevated in this area. I guess something did not go well in assembling.
Thank you
ioannis

@felmue
I have done all that. power is ok on the pins and they are new, just bought them so I guess contact is good.

@ajb2k3
neither red or green LED light up and also I wrote a small routine to check just to make sure.
It is definitely not charging!

Hello
I am having this problem that the bottom2 battery does not charge from the base. It would charge from the top port on the M5core2 but not from the charging base. Even the charging led does not light when the usb C cable is inserted at the base.
I tried opening a query with M5stack site but they only replied once to check the led and then nothing.
Please help!
Thank you
ioannis

can you give me some instructions how to apply the firmware update. there are no instructions. Have you try it? Is it working
Thank you

@robski
I am not sure about your question - are you asking about the main code or the sound making code?
I have tried a lot of different approaches to get an alarm sound but nothing worked. Last try was with https://github.com/Hagtronics/M5Stack-Core2/tree/main/Sound
but with no success.
I just need any working piece of code that makes a beep sound and I will add it to my main code.

Hello
I am trying for a whole day now to make a simple alarm sound when the temp measured by a sensor pass 85 degrees.
tried all the demo codes but none works.
Only one works with M5unified but it conflicts with my other libs
'''#include <M5Core2.h>
#include <Module_4RELAY.h>
#include <OneWire.h>
#include <DallasTemperature.h>
#include <M5_ACSSR.h>'''
PLEASE HELP anybody just a small piece of code for a alarm sound on the M5core2

@LostInSpace I am quite new to all this so could you post a simple code of making a beep with your library.
thank you
Ioannis

hello
I have similar problems with the AC measure unit.
I cannot even make the M5core2 to see it.
Anybody succeeded maybe with a firmware update or any other method?
Thank you

Hello
I am new to this - just bought a M5core2 and I am trying to connect it to download a simple program.
Do I need an SD card for that.
Thank you
Ioannis
