@tspycher
AFAIK: this are very simple transmitter/receiver modules. No protocol, no encryption, no guarantee for transmit/receive the correct data. You have to make your own protocol and data integrity functions.

Try to send something out from UART (not faster than 10kbps) and receive it on the other side. Be aware that disturbance could be possible as 433.92MHz is used in a wide range of applications like wireless thermometers, garage door opener, car keys, wireless doorbells, wireless power switches...

As you get the raw pulses out of the receiver it should be possible to receive and decode data from e.g. the thermometer oder switches. There are several protocol descriptions in the web.

If you want to send simple data from one to the other device, ESPnow could be the better option.

The CoreMP135 is a nice little device and made a good impression when I first tested it.

The file system of the debian image is quite small.

Is there a way to increase the size of the root partition? The usual way with "fdisk" and "resize2fs" doesn't work. The system no longer boots.

Is there a limit to the size of the FS?

It would be great if future images had a larger ROOT.

The ATOMIC SPK Base (NS4168) with UIFlow2 is compatible with various example projects for robotics and IoT. You can find UIFlow2 examples on the official Atomic Pi documentation or their GitHub repository for ready-to-use sample codes.

@ScheduleDisplay
Connecting to always ON USB Power will permanent charge your battery and hold it at fully charged level. Not the best state to store a lithium battery over longer time. Best will be to remove it (or at least disconnect).

@felmue Hi, felix i got it working finally. The issue is, on platformIO the library Arduinomodbus library and ArduinoRS485 library are the arduino ones and not the m5stack ones which is why i was getting error.
A fix to this was to just replace the internal files of library to the m5stack ones from github.
Thank you for the help.

The UnitV/StickV (K210) Devices are serial devices. You need the MaixPy IDE to program and preview. The UnitV2 Devices are small Linux Computers and have a USB- and WiFi Network interface.

Hello @Pajdzian

I measure about 62 mA charging current (at the battery) when using M5Launcher and the same amount when running Cardputer UIFlow2 or Demo firmware (the one preloaded).

So I am curious: what other firmware did give you a slower charging rate?

Thanks
Felix

Hi @scoobysnax

I also searched far and wide for a connector for the bat.

I used these: https://www.diyelectronics.co.za/store/connectors/1831-molex-125-2-pin-male-and-female-connector-cable-pair.html

So Molex PicoBlade 1.25 2-Pin is another term you can search for.

@PhilB79 said in M5CoreS3: "ERROR Device type unknown" when trying to connect both CoreS3 and CoreS3 SE to Server.:

@teastain
UIflow 2 / Select device / RED dot next to the CoreS3 graphic. Same applies to CoreS3

silly question but you are logged in to Uiflow2 with same login credentials as in M5Burner (bind)

@aitech Dont' throw that sensor away yet.
There is an error in the ENV_Pro demo code:
Line 51 should read Wire.begin();
After changing that it worked fine for me.
The interface address for the sensor is actually defined on line 57.
Pretty impressive sensor.

@ddhard I was thinking of using https://shop.m5stack.com/products/esp32-ethernet-unit-with-poe
in terms of space.
programming with UIFlow or Arduino IDE but I didn't see the esp32-ethernet-unit-with-poe controller in the UIFLOW list.

Even when connecting the M5Dial to USB while holding the rear boot button, only one COM port is displayed.
It’s unusual if two ports are not displayed, right?

@kdshawee87

Is there a possibility that it is conflicting with the Arduino macro?
#define min(a,b) ((a)<(b)?(a):(b))
This is a rough way of writing it, but in the header
#include <M5EPD.h> #include <Settimino.h> #undef min
Will it compile if I undef it?
However, in this case, the standard min cannot be used in this file.

@NVERD

I have burned my camera with the latest firmware (1.1.0) and the the long press on the side to get access to the config does not work by me either. But if I burn it with version 1.0.0 the long press works:
ab6e1815-ac1a-44af-b7bd-215ecdd804ad-image.png

However, if you can see an IP on the serial interface you have probably connected the camera to a network with a DHCP and you should be able to stream if your PC is connected to the same network.

But note that the urls are:
http://<CAM_IP>/stream for v 1.0.0.
and
http://<CAM_IP>/ for v 1.1.0.
