There are some relay boards that use an additional µC to owrk around the problem-
There are some hw-mods to work around,
I don't know of any effective sw "trick".
I added a 470µF capacitor between GPIO0 and VCC and it did the trick . Should I add 1K resistor to limit the current or the capacitor alone is enough
Currently working circuit : ESP 3.3VCC -> +ve lead of the capacitor -> -ve lead of capacitor -> ESP GPIO0
With resistance : ESP 3.3VCC -> 1KOhm -> +ve lead of the capacitor -> -ve lead of capacitor -> ESP GPIO0
which would be better and more stable ?
