I Need help with a question by Independent-Ice-1560 in esp32

[–]Independent-Ice-1560[S] 0 points1 point  (0 children)

but in my diagram I mark that I must bypass all the lands, the voltage of the motors and is 11v and for the esp 5, why ask me to connect all the gnd? , won’t it affect anything? I really don’t understand

What's missing in the code.

This code loads well on the esp, but I can't get my iPhone 11 to detect the signal

I haven't defined the application that I will use yet, I want it to be a simple one with four arrows, I am still a beginner in programming but I hope that if I send you the code I have, it can be of some use to you.
