Has anyone experience using these tiny boards? They have an external antenna connector, and Wi-Fi connectivity is an issue where I will be using them.
Hi
I have the same controller and some questrions.
when i want to install the Bootloader from the Wled Page
https://kno.wled.ge/basics/install-binary/
I have a error “A fatal error occurred: Invalid head of packet (0x47)”
esptool.py --port /dev/ttyACM0 --chip esp32 write_flash 0x0 ./esp32_bootloader_v4.bin
esptool.py v2.8
Serial port /dev/ttyACM0
Connecting…
Chip is ESP32D0WDQ6 (revision 0)
Features: WiFi, BT, Dual Core, Coding Scheme None

Running stub…A fatal error occurred: Invalid head of packet (0x47)
I dont know whats wrong…
Has anyone here a solution here?

Same problem here. I ended up making a Bluetooth scanner out of my MCU. It uses very little power in that role, I suspect the memory offsets have to be adjusted in the WLED software, but I never figured out where to specify the changes.
I recompiled with the latest GIT version and it works now.

Hi. what are the steps to get wled to work on xiao esp32 c3?
I updated my repository to current, then compiled a binary using this in platformio.ini:
[env:esp32c3dev]
extends = esp32c3
platform = ${esp32c3.platform}
upload_protocol = espota
# exchange for your WLED IP
upload_port = “your.ip.address.update”
platform_packages = ${esp32c3.platform_packages}
framework = arduino
board = esp32-c3-devkitm-1
board_build.partitions = tools/WLED_ESP32_4MB_1MB_FS.csv
build_flags = ${common.build_flags} ${esp32c3.build_flags} #-D WLED_RELEASE_NAME=ESP32-C3
-D WLED_WATCHDOG_TIMEOUT=0
; -DARDUINO_USB_CDC_ON_BOOT=1 ;; for virtual CDC USB
-DARDUINO_USB_CDC_ON_BOOT=0 ;; for serial-to-USB chip
upload_speed = 460800
build_unflags = ${common.build_unflags}
lib_deps = ${esp32c3.lib_deps}
PlatformIO (I’m using vscode) worked fine, and I flashed it through the USB the first time. After that, I put my changes (OTA) into the platformio_override.ini file. Yesterday I got a battery hooked up, and the xiao charged the battery overnight, however the device resets when I remove the 5V current from Vin. This is a minor issue at this point
The SEEED website was very helpful: https://forum.seeedstudio.com/

The only version I can get to work on the M5 Stamp and the Xiao Seeed Module is this
WLED_0.14.0-b2_ESP32_C3.bin
unfortunately this has no audio reactive and also makes a two-part picture when multiple displays are set up instead of a full picture,
does anyone have instructions or a BIN file that would run on these two modules?
I have already tried the following versions
WLEDMM_0.14.0-b15.21_esp32c3dev_4MB_M.bin
WLEDMM_0.14.0-b15.23_esp32c3dev_4MB_M.bin
Unfortunately, these do not start even after installation, and an OTA update aborts with an error message.
would be grateful for hints

Die einzige Version die ich auf der M5 Stamp und dem Xiao Seeed Modul zum laufen bringe ist die
WLED_0.14.0-b2_ESP32_C3.bin
leider hat diese kein Audio Reaktiv und macht auch noch ein zwei geteiltes Bild wenn mehrere Displays eingerichtet sind, anstatt ein ganzes Bild,
hat jemand eine Anleitung oder ein BIN File welches auf diesen beiden Modulen lauffähig wäre ?
versucht habe ich bereits auch folgende Versionen
WLEDMM_0.14.0-b15.21_esp32c3dev_4MB_M.bin
WLEDMM_0.14.0-b15.23_esp32c3dev_4MB_M.bin
leider starten diese auch nach der Installation nicht, und ein OTA Update bricht mit Fehlermeldung ab.
wäre für Hinweise dankbar

Quick note: After a few false starts, these small MCUs work very well. I compiled build 2306270 this morning and it is quite stable. Reports as Firmware: 0.14.0-b3.

Unfortunately i’m not able to compile WLED AR for the Seeed Studio ESP32C3.
The ini-files are very complex and i don’t know, what to change to get it with Audio reactive …
Is there someone, who can provide the platformio.ini and the platform_override.ini for the ESP32C3 and maybe also for the ESP32S3 from Seeed Studio?
You could try experimenting with the Unofficial WLED Compiler site.
They try and compact the options so you’ll have a better idea of what’s going on.
