Solved it, it returns the result in Dec, and not in Hex, don't know if there is a way to convert DEC to HEX

A) Even I am facing the same red "Connect Fail" error message every time I try to subscribe. I am using an M5Core Grey and cloudMQTT as a server. My intention is to send data from one M5 to another. The publish statement doesn't give the error whereas the subscribe gives an error every time. Can someone please help me with this?
B) Also, can anyone tell me how can I subscribe to my M5 from cloudmqtt so that I can know if atleast publish works or not?

Hello,

meanwhile it is possible to use the block "analog read pin (34)" from the blockpack "Easy I/O".
So I was able to bild the probram from user M5DOCS just with UIFLOW.

Unfortunally it just shows Numbers between 450 and 600 or so. And it dows not react to any sounds.

This is the python code of the blockly program:

=====
from m5stack import *
from m5ui import *
from uiflow import *
from easyIO import *

setScreenColor(0x222222)

label0 = M5TextBox(122, 84, "Text", lcd.FONT_DejaVu24,0xFFFFFF, rotate=0)

What did I do wrong?

@lukasmaximus

Thanks for the tip. I hadn't thought of that. I thought I would have to construct my own block.

Peter

@fmentiplay the left top hand corner is the UIFlow firmware version. in the "Check update" option. is the Desktop IDE software version . they are diffrence

@ecasti ok. the desktop IDE will update the demo program in next version

@world101 Thanx! After making new topics and setting them to QoS=0, and retain=0, it finally works with many MQTT subscriptions on both M5Stack and M5Stick-C! (1.4.4 and 1.4.5)

(PS! Just changing the old topics that had retain back to no retain, did not work, had to make new ones.)

@m5stack That worked! Thank you!

It seems there may be compatibility issues since uiflow firmware version 1.4.0 http://forum.m5stack.com/topic/1388/gps-data try to downgrade your firmware and retry your code

great job

Thanks so much I totally overlooked the plus sign and I was searching for a block in the map blocks. I’m grateful for you answering my question.

@m5stickfreakler Ok, I will tell the engineer these problem. Thank you

@world101 said in Speaker beep and Wait:

If you want additional testing help, you’ll need to post exactly what your entire flow/program looks like, including connections and Units. Obviously there is something unique in your setup that I don’t have, because it’s working for me.

from m5stack import *
from m5ui import *
from uiflow import *

@timerSch.event('timer1')
def ttimer1():
speaker.sing(220, 1/16)
pass

timerSch.run('timer1', 1000, 0x00)

--> It works if I download it to the device
--> It does not work if I run it from UIFlow

@m5stack
Yes Heart rate sensor, sorry for my typo error.
I will test it with arduino ide

@jpilarski

I agree this would be a good feature to have on uiFlow. Specifically, which block are you referring to on Adafruit MakeCode? Is it the "run in parallel" block?

However, from a MicroPython perspective, multithreading doesn't seem to be complete yet, according to this link. "This module is highly experimental and its API is not yet fully settled and not yet described in this documentation."
