Re: switch gpio 0 always high after boot
@riker: Are you specifically talking about this relay-modul?
Re: switch gpio 0 always high after boot
yes I am
even need a pulldown to boot up the esp-01

Re: switch gpio 0 always high after boot
and with this setup after powering up, GPIO 0 stays low?

It might flicker, if I remember correctly (only got one ESP-01 running).

Re: switch gpio 0 always high after boot
It works like follow at me:
ESP-01 on ESP-01S relay modul v1.0 with ESPEasy R148.
One resistor 10k between Vcc and CH_PD and one resistor 15k between Vcc and GPIO0 was soldered on the relay-modul.
No flicker, no "1" while or after boot !
ESP-01 on ESP-01S relay modul v1.0 with ESPEasy R148.

Re: switch gpio 0 always high after boot
ok, thanks, will try this.

Hi
where did you get the R148 from?
Only find 147

Re: switch gpio 0 always high after boot
I don't know anymore
Do you think, the R148 make any difference? If you wish, I would attach the R148 here today evening or send it as PM.
E.g. you can download it from here .

Because i didn't have a 15K with me, I tried and put a 10K resistor VCC<>CH_PD & 10K resistor VCC<>GPIO0, but it did not work.
Do you think it is because of the 10K i used and it's necessary to be 15K?
Thanks in advance,
Re: switch gpio 0 always high after boot
Yes maybe. I have tried several values...
Test it, with 4.7k and 10k in series !
