Help compiling a working esp-mdf Dev Kit -> Button

[fasani]

Hello there,
Trying to compile this in a ESP32-Wroom:

https://github.com/espressif/esp-mdf/tr ... kit/button

I tried the light already and it works great, attached an RGB light and been playing long controlling it from ESP-Mesh App.
Now this button seems to compile correctly but I could never configure it.

This is what I see on the Log:

So I don't see it ever opens BT to let me configure it. It just powers down, I'm missing something ?
Thanks in advance for your help!

Hi Fasani,

In order to configure the button, you need to connect with USB power supply.

[electronickiwi]

If you are running the button code on your own hardware you can pull the BUTTON_GPIO_USB_DETECT pin (GPIO_38 by default) up to 3v3 to emulate USB power being connected to charge the battery. You can change the pin number in button_driver.c at line 44.

This will then make the button visible to the mesh app so you can configure it.

Thanks electronickiwi!
That's a great piece of information I read anywhere else but here. I will try it out!
