3 & 4. Plus PlatformIO as well.

You could use the buzzer to give feedback when the button was pressed. :)

You might be using the wrong key to authenticate to the RFID sectors. See https://stackoverflow.com/questions/56225136/mifare-classic-standard-keys For my Mifare Classic tag, I go lucky with using FFFFFFFFFFFF as key B to access sector 4. Unfortunately they key cannot be changed in the UIFlow block, you have to manually change it in the Python code. For example: label0.setText(str(rfid0.readBlockStr(4, keyB=[0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF])))

Looks like rtc is included in one of the other files from m5stack import * from m5ui import * from uiflow import * setScreenColor(0x111111) rtc.setTime(0, 0, 0, 0, 0, 0)

Hi, I just ran some test and the LED doesn't work if the lithium battery in the base is below 3.8 volts. the microprocessor wont start up and so the M5StickC can't communicate.

OK it works. So for future reference this is what I did: Turn on the unit (mine is an M5StickC with UIFlow 1.6.6 firmware) press the M5 button quickly after that to enter setup mode (my screen shows <code>) side button to get the Setup menu M5 again to select it Switch Mode M5 again side button to select APP side button to select '..' at top M5 to go back to previous menu side button to select Reboot M5 to reboot From now on whenever you turn it on the Stick will run boot.py and then main.py in the /flash directory. If when it's so running you attach the device to a computer via the USB cable, you can interrupt whatever it is doing by starting Thonny and hitting ctrl-F2 (Stop/Restart Backend), which will bring up the MicroPython REPL prompt. Cool.

When I run that command I get: python --version Python 2.7.16 And when I try to import serial, I get the same error as with the esptool script: Python 2.7.16 (default, Jan 27 2020, 04:46:15) [GCC 4.2.1 Compatible Apple LLVM 10.0.1 (clang-1001.0.37.14)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import serial Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named serial So it appears that "pip" is symlinked to my python3 install, but "python" is still linked to the v2.7.16 default mac install. Thanks again for your help, will wait for an update!

Hi. I don't remember exactly, but these drivers should match: https://www.ftdichip.com/Drivers/D2XX.htm

When devices start up, go to setting and set connection mode to USB. Default is set to Wifi/usb.

@zontex Hi, I would also like to follow up on BLE in Core2 UI flow. Any update?

Hello @wadoadi I am glad to hear you got it working. And thanks for reporting back. Happy Stacking! Felix

@zontex thanks to answer, just to have confirm it is "safe" use a LDO to work at 3.3, i'm planning to connect one ENV II unit and at the same grove port A input pin 32 (or 33) of a Core 2. My doubt came from observe ENV unit schematic, where DHT 12 pin have pullup at 5V. Btw i don't have problem to put a LDO, my goal is share both sensors (one M5Stack and another external DS1820

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. Cheers Felix

@adamm Hi Adam, please send me email to roni@m5stack.com and I will personally take care of this issue for you.

@gettys said in UIFlow for M5Paper: When will UIFlow be available for M5Paper? 1.6.7? Hello, We are working on an update which will be released in the next version.

Hello, Could you try with the ssl settings disabled to see if it works? I'm wondering if it's SSL certificate path issues or your AWS server, have you copied the ssl key and certificate to the M5Stack device? make sure you import it in the right directory.

UIFlow firmware 1.6.6.1 Seems to fix this issue, please take a look and let me know if you guys have any more concerns :)
