Hello @felmue,
you are right, the top of M5Core2 and the AWS are identical. But the bottom is the challenge: The ground of the AWS shields the antenna. -> Yes, I tried the AWS version without the AWS M5GO2 bottom attached.
I tried this too:
@m5stack thank you for your answer.
This solution is just as trival as to go closer to the router. Unfortunately I cann't go closer and I cann't increase the transmit power. Can I connect an antenne to the "M5Stack Core2 ESP32 IoT Development Kit for AWS IoT EduKit"?
Hello,
I bought two "M5Stack Core2 ESP32 IoT Development Kit for AWS IoT EduKit" and two "M5Stack Core2 ESP32 IoT Development Kit".
Today I noticed that the AWS version did not receive the wifi as well. Both AWS version didn't work at my desk, but both non-AWS worked fine.
I got the errors at startup:
Wifi missing. Status=6
I (7634) wifi:new:<11,0>, old:<1,0>, ap:<255,255>, sta:<11,0>, prof:1

....
If I go two meters nearer to the AP both AWS worked fine, too.
Have anyone an idea what I can you do (without that I go closer to the AP) ?
Hello,
where could I find a good example of a moving face with eyes, nose and mouth for the m5stack?
Hello,
I use a lot of own libraries to control my home. Last library was a small extension of Adafruit_NeoPixel to show some status information.
I tested with four libraries (M5Core2.h, Wifi.h, Adafruit_NeoPixel.h and my lib) with a small test program with Arduino IDE and it worked fine. I used 16*16 led ws2812.
Then a changed back to my ESP-IDF and use the some libraries and some more stuff. If I started to switch some less on my WS2812 in green color, it worked 4 or 5 times without problems. At the next one switching event I got a problem on the second half of the leds:
Some switch the color from green to blue
Some led switch incorrect on
The first 100 to 120 leds all always correct. I think it is a interrupt problem, but in then Adafruit_NeoPixel.h interrupts stopped. I double-checked if this part worked:
// NRF52 may use PWM + DMA (if available), may not need to disable interrupt
#if !( defined(NRF52) || defined(NRF52_SERIES) )
noInterrupts(); // Need 100% focus on instruction timing
#endif
I also stop interrupts im my library for the critical part, but it didn't work. My unfounded suspicion is a unstoppable interrupt in M5Core2.h or similar.
Do anyone have an idea?
Hello,
in past I used some M5Stack modules at M5Stack and now I like to migrate to M5Core2. The challenge ist the different bus system.

Who has experience with using an M5Stack module on an M5Core2?
Hello @Rop,
thank you for your help. Do you test it with M5Core2-enviroment?
I generated a "FreeSerif34pt7b" from you website and compilation of my
program was ok.
If I started the M5Core2 and I used the new font to see the time, for example 08:29,
I saw 00 88 :: 22 99 in the first line und a second line with the top of the characters.
It seemed, that the length of the characters in the font was not okay.
Hello,
I need a big font for my application, in the factory example the EVA font is used.
I like to use a font like "Font72rle".
First step is to include the new font:
#include <Fonts/Font72rle.h>
How can I use the new font?
The function setFreeFont didn't work for me.
Hi @brus,
thank you for providing your repro. In the meantime I've put together my own version and I'm waiting for the official version of m5stack.
Hi @felmue,
I started M5Core2-Factory test, disconnected USB and go away. About 5 hours later I came back and tried to switch on M5Core. Nothing happened.
I connected USB, flashed the M5Core2 with the factory test program and everything worked fine.
At the last day I used my RTC-library with alarm functions and more and it worked continuously.
Cheers
