@felmue Thank you very much for your reply.

Hello,
I have understand that the M5 stack paper can wakeup from the shutdown mode by long pressing the side button but sometimes it is not feasible.

Is it possible to configure M5 stack paper in a way that:

1. It will wake up from short press of the side button?
2. It will wake up using Port A, B or C by connecting the external button? e.g this button from M5

Hello,
I am facing the same issue and not able to display the images on to the M5 Paper. I have tried both canvas.drawPngFile(SPIFFS, "/smiley.png", 0, 0);
and canvas.drawJpgFile(SPIFFS, "/smiley.jpg", 0, 0); but no luck.
I already included #include "SPIFFS.h" and initialized SPIFF using M5.begin(true, true, true, true, false);. The png and jpg files are inside the data folder. SPIFFS.open("/smiley.png") is able to open the file however it is not printing any file content on the console.

I think it is required to format the SPIFFS for the first time, as mentioned here so I followed these steps but ESP32 Sketch data upload is not appearing in arduino 2.0.

However I am able to display the png image using canvas.drawPngUrl("http://imageUrl"); but it is taking more time and quite slow.

Could you please help me in understanding what I am doing wrong?

Hello,
I Got the GFX font header file (by converting the Roboto.ttf file). Loaded the font file using canvas.setFreeFont(&Roboto_Medium50pt7b) and then display the text using canvas.printf(textString.c_str());.
It is working fine and display the text properly but when I am giving some special characters äöü then they are not appearing on M5stack paper.
Can someone please guide me what I am doing wrong? Am I missing something?

Thanks

@felmue Hello Felix.
Thank you very much for your help.
I get it working using the hour field with some little changes.

@felmue Hello Felix.
Is it possible to provide me the working code snippet with longer than 4 hours sleep duration?

Or

Can you please check if there is any problem with the code snippet I posted earlier?

Thanks

@felmue Hello Felix.

1. I also already had delay (10) before M5.shutdown();
   Do I2CEnable need to be TRUE in M5 initialization? to use I2C commands?
   I have it False in M5 initialization call M5.begin(true, false, true, true, false);, could this be a problem?
   However, it is working fine if the sleep duration is less than 4 hours

2. M5Paper has 100% battery, I can restart it manually by pressing the side button. The battery is showing as 100%

@felmue I tried longer sleep duration of 9 hours and unfortunately the device didn't wakeup.
Is it possible that M5.RTC.setAlarmIRQ(wakeupDate, wakeupTime); also has a limitaiton of max 4 hours of sleep duration?
