I had problems with the device resetting when driving a relay that was switching 240volt load. Module was the one with 2 rows of 4 pins, it would reset occasionally when relay was closed, and often when it was subsequentially opened. Pulling the reset up with 10k resistor to Vcc and down with 100n capacitor to ground seemed to help somewhat. A 10n capacitor between Vcc and ground, mounted on the directly on the board's pins solved the problem once and for all.

Hope the helps, Cheers,

@steves I have exactly that problem.
I'll be very happy if you could specify me all the components you use (power source, type of capacitors, transistors, diodes...) and how you connect them (which pins, solding, breadboard...) so I could do the same thing in my project.

Thank you!

Hello Felipe, I'm planning to do a writeup of the project for my blog in the next couple of days. I'll post a link here for you when it is done. Cheers,

If you mean me, there is a layout file from my pcb in a post before. If you dont like get extra programm i can make a screenshot too. Here are 2 pictures too: http://www.mikrocontroller.net/topic/349219#3938252

- Sun Mar 08, 2015 12:58 pm #11591 I've found a work-around to help with interacting using Lua Loader and a ESP with RF interference.
As quickly as possible after powering up the ESP send this command to it:
wifi.sleeptype(wifi.MODEM_SLEEP)

This seems to shut off the radio.
Once I do this I can use Lua Loader to upload code, compile it, etc with no more RF problems.

Once you're ready to test with the radio again enter:
wifi.sleeptype(wifi.NONE_SLEEP)
to turn the radio back on.
