Hi.
Thanks for pointing that out.
I’m sorry for the mistake in the code. It is fixed now.
Regards,
Sara

Some of them seem to have a bit of an ‘issue’: apparently the antenna placement is quite critical and some boards have components placed too close to the on board antenna, reducing the WiFi capacity. Somewhere on hackaday is a description on how to solve that with a minimal piece of wire that can be shaped a certain way and increase the wifipower again:

Hi,
look to your sketch:

Great!
I’m glad the issue is solved.

Hi.
Maybe you have a different board version?
I didn’t have those issues with my board.

However, notice that if you uploaded a deep sleep sketch to your board, it will be sleeping when you try to upload code.
You need to right the RST button several times right after pressing the upload button, so that the IDE can catch your board awake.
If you can’t, it may be useful to erase the flash to start again: https://randomnerdtutorials.com/esp32-erase-flash-memory/

Sara

That’s great!
Thanks for letting me know. Super useful information.

Hi.
Yes, that’s what we did.
That’s why we don’t get the lowest power consumption.

After you try out those options, can you share your results?

Regards,
Sara

Yes. You’re right.
The LEDs are definitely consuming additional power.

Hi.
You may have a different ESP32 C3 mini board.
The onboard LED of mine is on GPIO 8.

When you say the sketch is not running, what happens exactly?

Sara
