Add Content-Type with IoTcloud.Azure (import IoT_Hub)

JanNew — Invalid Date

When i use the library and send message to IoT_hub the custom body is Base64 encoded when i use a message route to Cosmos DB. Is it possible to add system properties to the azure object?

I see people adding the Content-Type and Content-Encoding utf-8 would solve the issue...

azure = IoT_Hub(connection_string='HostName=.azure-devices.net;DeviceId=myCore2;SharedAccessKey=< right>')
azure.start()

azure.publish_D2C_message(msgJSON)

Micropython Support for M5Stack Core2 + LAN W5500 Module

felmue — Invalid Date

Hello @AdamMillionP

having two devices using the same IP address is never a good thing in any network.

The other thing which needs to be different between clients is the MQTT client id as it is used by the Mosquitto broker to distinguish between clients.

Thanks

ESPNOW and wifiCfg

fbritop — Invalid Date

I have a Core2 which connects to internet as a Station.
Also I'm using espnow to connect to nearby ESP01 relays.

I cannot figure out how to enable ESPNOW as AP, and Wifi connection for internet throught a router as a STATION.

If I config the STATION, when I configure next he ESPNOW, Wifi STATION disconnects. If I connect first (init) the ESPNOW, then the WiFi STATION, ESPNOW does not work.

I know that ESP can work at the same time as an AP and STA, but here I cannot figure out how to do both at the same time with MicroPython

Here I connect to my Wifi

Here I init the ESPNOW

I cannot figure how to run both modes at the same time, which I´m sure ESP32 is capable

atom motion control servos independently or simultaneously, access each channel

teastain — Invalid Date

Yes, you would send position or speed values to each channel.

There should be an example in the documents.

If I misunderstand let me know and I will research further.

Arduino IDE, no problem, and I’m sure it is facilitated in UIFlow.

atom motion with micropython

Hello @thop

in UIFlow online check out Base - Motion. On the Python tab you'll see how to use it with MicroPython.

Solved - lcd.xxx() don't work

Peter — Invalid Date

I have accessed the M5Stick C Plus display in Micropyton with lcd.print() in the past. Suddenly this does not work anymore.
from m5stack import *
from m5ui import *
from uiflow import *
lcd.clear()
Traceback (most recent call last):
File "", line 1, in
NameError: name 'lcd' isn't defined
Can someone explain me how to use the internal M5Stack Micropython commands again.
As IDE I use Thonny.

After a restart of Thonny, it works again.

m5list on Core2

WoeTan — Invalid Date

Hi there.

I am trying to use the m5list on the Core2.
I am using the following Micropython code

(Sorry, I did not get to post as a 'real' code snippet)

from m5stack_ui import M5List
lGraph = M5List(0,0)
h1 = lGraph.add_label('PT1')
h2 = lGraph.add_label('PT2')
lGraph.get_sel_label_index()

Depending on what is selected, I could retrieve the selection with

lGraph.get_sel_label_index()

So, I get 0 or 1.
So far so good.
When nothing is selected, that means the display was touched somewhere not within the list or when the list was created and it was not clicked on a list item, then the function does not return any thing and blocks the Core2 until a manual reset occurs.
Could you please help me to avoid this behaviour?
Thank you

Core2 with Visual Studio Code

@kiwilogan I found that updating VSC and uninstalling and re-installing the M5Stack extension made that magic "Add M5Stack" button appear.

M5stickC and Plus MicroPython Screen Driver

JackH — Invalid Date

Hi,

Where can I find the MicroPython screen driver for M5stickC and Plus?
I need numpy/ulab so I am using this firmware with good success.

Problem is, the only access to the screen I can get easily is via low-level ST7735 access, which only allows for the tiniest of characters in portrait mode only. Where is the LCD driver for MicroPython, with similar functionality to that in UIFlow?

Thanks!

MtStickC accuweather.com mini weather station

robalstona — Invalid Date

Yes, you must replace for example read temperature block with block which reads temperature from hat you use. Ewentually adds new block lcd.print for printing pressure and humidity with appropriate blocks reading data from these sensors But problems may be with icon and weather description, because the weather description and icon number corresponding to the current weather is downloaded from the accuweather.com website. some fun and testing with font type, coordinates and colors and it will work

Code only works from Visual Studio

Given that I can now see the console, I determined that it throws OSError if the http GET fails. Which is a weird error to throw, but OK. So I put that in my except: clause, and it's humming away!

M5atom Matrix library (micropython)

robalstona — Invalid Date

@conrad i use uPyCraft to transfer files to atom. You can also connect uPycraft with atom and use REPL (something like command shell) to use interactive micropython command interpreter). With UiFlow it is possible but you must first transfer libraries to /apps folder in flash memory and use advanced->execute->execute code to run appropriate commands, ewentually write raw code in Python tab. In this option code probably properly run only when you download it to device (not run with play button).

If i find some free time then i create custom block to scroll text using recently added Hardwares->Rgb->set atom matrixblock, but i must do some experiments with it.

Глюки в Cloud. Невозможно сохранить файлы.

k4m454k — Invalid Date

Добрый день. Есть у меня Fire с постоянным кодингом под него с помощью cloud.m5stack.com.
Мало-мальски с глюками бороться научился и спокойно заливаю код.

Но приехал ко мне ещё один Fire и там сразу проблема.
Добавил я его в свой аккаунт cloud, но любая запись падает с ошибкой. Будь то сохранение измененного main.py, или загрузка нового файла, всё падает с ошибкой.
Грубо говоря, написал я в main.py свой код, нажал "загрузить и запустить", а он заливает main.py который по умолчанию.
При этом, в этом же аккаунте у меня висит мой первый Fire, где всё работает и сохраняется.
Что за дичь? Куда копать?
