disable onboard blue LED on D1 mini

#1 Post by TungstenE2 » 21 May 2020, 08:26

Hi all

how to disable blue onboard LED on D1 mini?

I already set GPIO-2 (D4) output to low and set wifi LED option to none, but LED is still on after reboot.

Worst case, desolder it. But have you tried:

Code: Select all

On System#Boot Do
 GPIO,2,1
EndOn
Please be aware that setting it to high will make it turn off.

thx, this fixed the issue. So old information in forum on GPIO-2 (D4) output to low was wrong. It has to be high.
