Esp-01 OTA without GPIO0 connectes to GND

Hi everybody,

I’m using GPIO0 as general I/O pin and its started as HIGH when the ESP is powered up. Thats why i think, i cannot use OTA and Blynk.air.
So do you have any solution for that matter? (By the say, changing the. GPIO0 to any other pins is much harder due to my project PCB.)


I doubt if GPIO0 is the issue, but it depends on what symptoms you’re seeing.

What code are you using?
What happens in Blynk.Air when you try to choose the device, upload code etc?
