Does your mobile phone or tablet show a new wifi station that you can access?
Edit: change the dropdown box from station to acc-point then try again. if you run a wifi scan on a device you will now find a new esp device.
try to use m5 burner, then erase or load new firmware thru it, i do have one core unit which suddenly stopped to display anything on lcd screen, i can connect to it, load projects but nothing is showing up on screen except backlight is on.
Thanks @teastain,
i try it since few days, but i can't find any information how i must connect the Motor Modul.
I use this one: Link
Have you an idea how i must connect ENA (for PWM), IN1 and IN2 with the M5stack core and set the motor speed with PWM?
My M5 Stick CPlus 1.1 keeps rebooting. I uploaded a program called laserline. It looks like the program is working but it wont stay on. The battery showed low when I first turned it on before the upload. and when I unplug it it will power down after about five min but won't come back on. Tanks in advance. flashG
@Powersoft
Hello, after contacting M5Stack support the problem is probably the flash chip, M5Stack is replacing my M5Paper.
I had performed this upload test at slow speed but without improvement. Thanks for your help
@sodoku Thanks. I just got an email that the M5's are back in stock... Digikey still showing backordered though. Guess i'll have to order from M5 directly.
Hello @ckuehnel
Without opening M5CoreInk you probably cannot measure battery voltage with a multimeter. However you can use GPIO35 to read the battery voltage. Check out float getBatVoltage() here.
BTW: I've opened my M5CoreInk today and added some photos to my page (link below). Measuring power consumption in light sleep, deep sleep and shutdown will be next.

I stumbled on this restriction again, and dug a bit deeper in the issue.
It appears that the hardware is not limiting the baudrate, but the M5Stack library. More specifically, M5.begin();
Luckily, you can skip the UART init, and do it yourself like this:
M5.begin(true,true,false);
Serial.begin(2000000);
Serial.flush();
And now it works for 2000000 baud.
Hello @AndyT
hmm, strange, if anything I'd expected the M5Stack Gray to work with low brightness level and the M5Stack Black to not behave due to the fact that the M5Stack Gray has additional hardware (e.g. IMU) consuming power to keep the device powered on.
That said, I suspect the IP5306 switching off due to too light load. Try to add the following statement before going into deep sleep. It should prevent the IP5306 from shutting down under light load.
M5.Power.setPowerBoostKeepOn(true);
Happy Stacking!

@sparkinman
Check that:
You have added the M5Core2 library and are doing #include <M5Core2.h> and not using M5Stack.h. Until they merge it my Pull Request and release a new version, my version is more like it will be, better documented and has graphical buttons. (Simply clone it or get the zip file and unpack so that M5Core2 is a subdir of your Arduino libraries dir.)
In Arduino Preferences, you have added https://m5stack.oss-cn-shenzhen.aliyuncs.com/resource/arduino/package_m5stack_index.json as an "Additional Board Manager URL"
Make sure you then select M5Stack-core2 from the "Tools / Board / M5Stack-Arduino" menu.
If this is all good, then you should be able to run one of the examples from the "File / Examples / M5Core2" menu.
Hello @veryalien
Sorry to hear about your troubles.
I looked into the factory test program today and got it to compile and running after enabling PSRAM, the above mentioned fix in SetLDOVoltage() and some cleanup of the old Wire vs Wire1 fight that seems to come back every now and then. I wished the developers could make up their mind and always use Wire for internal I2C devices. Oh well.
The factory test code does something interesting regarding vibration motor voltage. During the startup sequence it is first set to 2 volts, then the motor is quickly turned on and off again and then later on it is set to 3.3 volts (not sure why though). When testing the vibration motor from within the settings menu the latter voltage is used.

@efried said in Snap in fixture?:
I can't find such in the webshop.

thanks
This isn't an M5Stack product, that is a user created free to download addon that needs 3D Printing.
