The Atomic QRCode2 Base (SKU: A133-B) typically draws a working current of around 174.18 mA at 5V when connected to an Atom-Lite. Your observation of 170 mA is within the expected range, so this behavior is normal.
However, if the device is heating up significantly, you can try the following to reduce power consumption:

Use Pulse Mode: Ensure you are using the TRIGGER_MODE_PULSE mode to minimize continuous power draw.
Adjust Lighting: Reduce the brightness of the fill light (set_fill_light_brightness) or turn it off when not needed (FILL_LIGHT_OFF).
Limit Continuous Operation: Avoid prolonged continuous scanning by using shorter decode delays (set_decode_delay).

If the issue persists, check for firmware updates or ensure proper ventilation around the device.

To create custom buttons using touch coordinates and visual elements (like rectangles or images) in UIFlow 2 for your Paper S3 (SKU: C139), you can follow these steps:

Use Touch Coordinates:

The Paper S3 has a touchscreen, and you can detect touch events by checking the coordinates where the screen is touched.
Example code snippet in MicroPython:import M5
from M5 import Widgets

def on_touch(x, y):
if 100 <= x <= 200 and 100 <= y <= 200: # Define your button area
print("Button pressed!")

M5.begin()
Widgets.fillScreen(0x222222)
label = Widgets.Label("Touch the screen", 50, 50, 1.0, 0xffffff, 0x222222, Widgets.FONTS.DejaVu24)

while True:
if M5.Touch.getTouch():
x, y = M5.Touch.getX(), M5.Touch.getY()
on_touch(x, y)
M5.update()

Visual Elements:

You can draw rectangles or images to represent buttons on the screen.
Example to draw a rectangle as a button:import M5
from M5 import Widgets

M5.begin()
Widgets.fillScreen(0x222222)
button = Widgets.Rectangle(100, 100, 100, 50, 0x00ff00, 0x222222) # Green rectangle

while True:
if M5.Touch.getTouch():
x, y = M5.Touch.getX(), M5.Touch.getY()
if 100 <= x <= 200 and 100 <= y <= 150: # Check if touch is within the rectangle
print("Button pressed!")
M5.update()

Images as Buttons:

You can also use images as buttons by loading an image and checking if the touch coordinates fall within the image bounds.

Additional Notes:

The above examples are simplified. You may need to adjust the coordinates and logic based on your specific requirements.
For more advanced features, refer to the Paper S3 documentation.

@Jose-Manuel The error you're encountering (getaddrinfo() returns 202) typically indicates a DNS resolution issue, meaning the M5Tough is unable to resolve the hostname uiflow2.m5stack.com. Here are some steps to troubleshoot and resolve the issue:

1. Check Network Connection

Ensure the M5Tough is connected to a stable Wi-Fi network.
Verify the Wi-Fi credentials (SSID and password) are correctly configured.

2. Verify DNS Settings

If the device is unable to resolve the hostname, try using a different DNS server (e.g., Google's DNS: 8.8.8.8 or 8.8.4.4).
You can configure this in the Wi-Fi settings or DHCP settings of your router.

3. Test Connectivity

Use a tool like ping or nslookup to check if the hostname uiflow2.m5stack.com is resolvable from another device on the same network.

4. MQTT Configuration

Ensure the MQTT broker settings (hostname, port, client ID, etc.) are correctly configured in your code.
If the broker requires authentication, verify the username and password.

5. Firmware Update

Ensure the M5Tough is running the latest firmware. Outdated firmware might have bugs related to network connectivity.

6. Debugging

Add debug prints in your code to check the Wi-Fi and MQTT connection status before attempting to send messages.
Example:print("Wi-Fi connected:", wifi.isconnected())
print("MQTT connected:", mqtt.isconnected())

7. Alternative MQTT Broker

Temporarily switch to a public MQTT broker (e.g., test.mosquitto.org) to rule out issues with the uiflow2.m5stack.com server.

Example Code for MQTT Connection (MicroPython)
from umqtt.simple import MQTTClient
import network

Wi-Fi Configuration

wifi = network.WLAN(network.STA_IF)
wifi.active(True)
wifi.connect("YOUR_SSID", "YOUR_PASSWORD")

Wait for Wi-Fi connection

while not wifi.isconnected():
pass

print("Wi-Fi connected:", wifi.isconnected())

MQTT Configuration

mqtt = MQTTClient("client_id", "test.mosquitto.org", port=1883)
mqtt.connect()
print("MQTT connected:", mqtt.isconnected())

The CoreS3 (SKU: K128) and CoreS3-SE (SKU: K128-SE) use AXP2101 power management chips and are designed with low power consumption. However, to further reduce power consumption while maintaining full functionality, you can consider the following aspects:

Power Supply Configuration: You can configure the XPD_SDIO_REG to select the power supply from the regulator or an external power source.
Voltage Selection: Configure SDIO_TIEH to select a 3.3V or 1.8V voltage.
Under - voltage Detection: The CoreS3's ESP32 - S3 chip has an under - voltage detector that can detect the voltage of some pins. When the voltage drops rapidly below a preset threshold (default is 2.7V), it can turn off some power - consuming modules to save power.

In addition, the power consumption of a device is also affected by factors such as the brightness of the screen, the operation mode of the Wi - Fi module, and the working state of other components. You can try to adjust these factors to reduce the power consumption of the CoreS3.
