#73949 Having similar issues. ESP boots, and can see it over wifi. I've put the pull up resistor in, the link to CH-PD, but the relay will not pull in. So I'm wondering what happens now, what would happen if I took out both the pull up and pull down resistors?

Perhaps someone could outline or picture how they made their boards work? Please?

#73950 Put a Vcc link to CH-PD and a pull up resistor to gpio0, finally the ESP boots and I can see it over network.

Thanks chaps this has caused many hours of anguish! And a few notes to the supplier who was as useful as a chocolate teapot.
