@ DMeekelenkamp : thanks for the post man. I was desperately looking for proper circuit connections.I'll update the status once I test it.

Thanks dude. It helped me a lot.I'll come back to you once I test it.

Thanks buddy. I'll get to you .

What do you mean by normal connections?? I'm not even able to see any access points of esp . Please tell me the normal circuit connections

Actually Relay is gettin switched even with 3V . Esp8266 is able to switch relay.

Can someone tell me about circuit connections & configuration of settings using arduino IDE for ESP8266 12E module for uploading easy esp8266 firmware. I uploaded the firmware into esp8266 01 & its working. But unable to upload it to esp8266 12E module. What type of Board should I select in ...

yup 2.5 -3V

Case 1. Led

on booting :

A spike of 1.5-2V is measured for fraction of sec.

after that I am able to OFF & ON.

Default state OFF 0.1 -0.2 V
ON state 3-3.15V

Case 2 : relay

2.5-3V is measured . Default state ON

OFF state 0.1-0.2V

Maybe start a new topic?

Thanks Martinus , I have already started a new topic

kr0815 wrote:And when in low state ? Both after boot and when switched once on and off ?

around 0.2V

kr0815 wrote:could you meassure the voltage on the GPIO ?
With relays and LED, after Initial start and later, when working as expected ? Is it really 0V and 3.3V ? Or something inbetween ?

Not exactly 3.3V around 3-3.1V in both the cases.

My problem is case 1: step 1: On powering circuit: gpio 00 -> Led positive common gnd Led state-> OFF Using openHAB I send ON command -> LED ON OFF command -> LED OFF step 2: openHAB ON -> LED ON openHAB OFF -> LED OFF It works perfect with LED. and also with Arduino UNO . Initial reading of UNO is ...

That was a good explaination. I even read your artice. My problem is case 1: step 1: On powering circuit: gpio 00 -> Led positive common gnd Led state-> OFF Using openHAB I send ON command -> LED ON OFF command -> LED OFF step 2: openHAB ON -> LED ON openHAB OFF -> LED OFF It works perfect with LED....

I think you didn't get my question. I am able to drive relay with 3.3 v input . My problem is , Case 1 : esp8266 01 gpio 00 connected to LED positive terminal gpio 02 conneted to LED2 positive terminal I use openhab to switch on/off gpio pins . When I power on esp8266. default state of LED's = OFF I...

It is similar to : http://www.ebay.in/itm/1-Channel-Isolated-5V-Relay-Module-Coupling-For-Arduino-PIC-AVR-DSP-ARM-119-/321920629860?_trksid=p2054897.l5659 . I am not using any external devices. my connections are CH_PD -> 3.3V GPIO 0 -> Input to relay 1 GPIO 2 -> Input to relay 2 VCC -> 3.3V GND -> ...

I have weird problem .I am using esp8266 01 to switch relays using openHAB mqtt. When I power on the circuit with relays connected , relays will be in ON state by default. With the same circuit , if I connect LED to gpio pins of esp8266. By deafult they are in OFF state. Did any of you encountered t...

Thanks a ton buddy :) :) . Finally able to config my esp8266-01 . Can you please tell my the circuit connections for esp8266-12E ? Wiring is the same on ESP-12E as on ESP-01 - except that you need to pull GPIO 15 low (both for programming and normal operations). This can be also be done with a 10k ...

Do you mean to say that I need to place a button ? While uploading program GPIO 0 should be connected to GND . After Uploading It should be either HIGH or Floating (no connection). ? Exactly. The recommend design is pulling up GPIO 00 and GPIO 02 with a 10k resistor to 3.3V, but directly to 3.3V or...

Wiring: RX -> TX TX -> RX CH_PD -> 3.3V GPIO 0 -> GND VCC -> 3.3V GND -> GND GPIO 00 connected to GND put's the module in programming mode. The pin needs to be high (preferable pulled up with a 10k resistor) for the module to boot (you might get away with having the pin floating) - Jan Do you mean ...

Could you start the serial monitor in Arduino and set the baud rate to 115200. Then power on the ESP and check the output on serial monitor. Post the results here, so we can have a look at the boot process. RX -> TX TX -> RX CH_PD -> 3.3V GPIO 0 -> floating (Didnt connect to anything) VCC -> 3.3V G...

:roll: I recently bought esp8266 01 modules similar to URL : http://www.electrodragon.com/product/esp8266-wi07c-wifi-module/ I came across easy esp8266 firmware which is awesome. I want to some guidance on how to upload firmware onto esp8266 01 . I tried all the steps mentioned in the tutorial on up...
