ESP8266 Community Forum

- Mon Jun 29, 2015 6:45 am #21963 Im used the basic example. The result is same my code.

Nope, my ESP Tx pin is connected to the arduino nano D10(softwareserial Rx).
In my code used first the nano rx pin. Same result.

But tested with coolterm terminal too te ESP with two type of TTL-USB converter, same result.

Nobody tryed to control arduino with ESP at the serial oins? I cannot find tutorial, or help in this problem.

- Mon Jun 29, 2015 8:58 am #21967 OK back to the roots:

Take only the ESP8266 and a USB-TTL-Converter (best is one with 3,3V logic-level)
3,3V and GND on the ESP,
TX (ESP) -> RX (USB-TTL)
RX (ESP) -> TX (USB-TTL)

Start a serial console (Serial monitor of the arduino IDE, or HTERM, or....) and tell us......
I tried this with an ESP-01, serial monitor of arduino IDE with ESP8266 add on, and your postes ESP-code. And I got only one "on" or "off".

my ESP8266: ESP-01 V2 / ESP-12E (NodeMCU)
ESP8266 Arduino add-on
Arduino IDE 1.6.5

Without arduino.
Esp connected to pc with CP2102.
Opened the Coolterm.
Connected to the esp at the COM6.
From a browser go to the 192.168.1.5/gpio/1 once
The result on the terminal:
off
off
off

When trying from phone the ip, always got 3 "on" or "off" receive.
When trying from pc browser (chrome) once got one "on", next time got three "on", next time one "on" then next time three "on"...

Interesting.
