Hello,
With the Core GRAY i had the feature to upload compiled .bin program files via SD card with the LovyanLauncher and select from menu. Because the GRAY is no longer available i want to move to Core2. But i do not find a solution for uploading program with SD card. Sadly the LovyanLauncher is discontinued as seen here and will not be updated for Core2.
Is there any other tool to do this with Core2? Thank you for any response.
Regards Patrick

Thank you Felix for the quick answer. I confess did not looked in the M5 source. So its more a feature than a bug.
My problem was, that i am communicating with other hardware where i can not easily change the baudrate to 115200. Must touch the M5Stack lib for that.
A property for baudrate value would be nice.
Still do not understand why the problem was only since the esp32 release to 1.0.5 and not earlier.

Hello,
I would like to report an issue with M5Stack Core GRAY/BASIC.
If you have installed esp32 board lib v1.0.5 and run code like above, you will find that the statement Serial.begin() has a conflict with the statement M5.begin(). You will never get into the loop.
With esp32 1.0.4 and lower it is ok.
The strange thing is that when i remove Serial.begin() it works and still prints with 115200 baud.
I do not know wether the issue is in the lib esp32 or m5stack.
Regards Patrick

Here is an example:
/******************************************************************************/
#include <M5Stack.h>

int i = 0;

void setup(void) {
Serial.begin(115200); // comment this line if esp32 lib 1.0.5 is installed!

M5.begin();
M5.Power.begin();
M5.Lcd.setCursor(10, 20, 4);
M5.Lcd.setTextColor(TFT_YELLOW);
M5.Lcd.setTextSize(1);
M5.Lcd.print("Hello World!");
delay(2000);
M5.Lcd.clear(TFT_BLACK);
}

void loop() {
M5.Lcd.setCursor(10, 20, 4);
M5.Lcd.fillRect(10, 20, 100, 19, TFT_BLACK);
M5.Lcd.println(i);

Serial.println(i);
i++;
delay(1000);
}
/******************************************************************************/

Find the bug:
"for(int i=0; i>=100; i++) {"

How do i print these characters to LCD? I own the M5stack Grey.
With other Arduino LCD's i did "\xEF" to print 'ö'. But with M5 LCD it did not work.
Is there a document showing wich characters are supported in the LCD font?
