Also: don't.do.anything.stupid. :D

And detailed info on functions:
https://www.arduino.cc/en/Reference/SD

No source code there but all functions detailed and explained how to use
Because blockly, Im sorry, is just lame

we had open source part UIFlow lib code. in this github :https://github.com/m5stack/UIFlow-Code

Taking into account some lib data security issues, we will not open source all libs for the time being, so you can talk about which libs users want, we will consider if open source these lib.

from m5stack import *
from m5ui import *
from uiflow import *
from ble import blynk

setScreenColor(0x222222)




label0 = M5TextBox(52, 10, "Text", lcd.FONT_Default,0xFFFFFF, rotate=0)
label1 = M5TextBox(46, 49, "Text", lcd.FONT_Default,0xFFFFFF, rotate=0)
circle0 = M5Circle(141, 122, 15, 0xFFFFFF, 0xFFFFFF)

val = None
message = None



blynk.init('fire', 'xxx', blynk.BLE)
while True:
  circle0.setSize(val)
  wait_ms(2)


@blynk.handle_event('connected')
def blynk_write():
  global val, message
  rgb.setColorAll(0xff0000)

  pass



@blynk.handle_event('write v2')
def blynk_write(*args):
  global val, message
  val, message = args[0], args[1]
  label0.setText(str(val))
  label1.setText(str(message))

  pass

Here is the manually adjusted code that connects with blynk.

from m5stack import *
from m5ui import *
from uiflow import *
from ble import blynk
blynk.init('fire', 'xxx', blynk.BLE)
setScreenColor(0x222222)


label0 = M5TextBox(52, 10, "Text", lcd.FONT_Default,0xFFFFFF, rotate=0)
label1 = M5TextBox(46, 49, "Text", lcd.FONT_Default,0xFFFFFF, rotate=0)
circle0 = M5Circle(141, 122, 15, 0xFFFFFF, 0xFFFFFF)

val = None
message = None



@blynk.handle_event('connected')
def blynk_write():
  global val, message
  rgb.setColorAll(0xff0000)

  pass



@blynk.handle_event('write v2')
def blynk_write(*args):
  global val, message
  val, message = args[0], args[1]
  label0.setText(str(val))
  label1.setText(str(message))

  pass

while True:
  circle0.setSize(val)
  wait_ms(2)

In the example above when the message variable is shown using label1.setText(str(message)) it shows the following ['255']. What is the most effective way in micropython to remove the [] and ' ' and convert message variable to an integer. I am using

which outputs this

@blynk.handle_event('write v2')
def blynk_write(*args):
  global val, message
  val, message = args[0], args[1]
  message = str(message.replace("'", '').replace(']', '').replace('[', ''))
  label0.setText(str(val))
  label1.setText(str(message))
  circle0.setSize(int(message))

  pass

but should generate this

@blynk.handle_event('write v2')
def blynk_write(*args):
  global val, message
  val, message = args[0], args[1]
  message = str(message).replace("'", '').replace(']', '').replace('[', '')
  label0.setText(str(val))
  label1.setText(str(message))
  circle0.setSize(int(message))

  pass

edit: sometimes first two. I have to change order for publish third configuration topic
