Hi
I have the same problem.
powersupply is fine 5 V in.
But ESP is not starting / Booting when GPIO 0 and(or 2 are attached.
tried also EN CHg Pin also connect to VCC in

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?

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.

I used a jumper from Vcc to CH_EN and a 9-11K pull-up resistor for GPIO0. The ESP boots but the pull-up does not seem to trigger the relay.
Hello m_elias,
I have the same module and faced the same problem while considering it was making no sense to have to wire GPIO. Anyway, it has been the only solution I found to get the module booting.
Have you been further yet? I am newbee here and all experiences for the basic steps are interesting for me.
