Overview

These apps accomplish the following:

-- ESP8266-EVB-blinkLED : Blink by green LED on ESP8266-EVB

-- arduino_style :

-- esphttpd : Advanced web-server for ESP8266-EVB (Config, Rele, Button).

Build toolchain

https://github.com/pfalcon/esp-open-sdk is easy to use, it basically does all on its own.

  • Clone the repository to /opt/Espressif (or somewhere else, this path seems to be preferred by some people)
  • Install dependencies: sudo apt-get install make unrar autoconf automake libtool gcc g++ gperf flex bison texinfo gawk ncurses-dev libexpat-dev python sed
  • make, wait a few minutes, done.
  • Add export PATH="${PATH}:/opt/Espressif/xtensa-lx106-elf/bin to your .bashrc, .profile, .zshrc, whatever. Or just run it every time you want to use the toolchain.

In some versions of the SDK there seems to be a problem with some type definitions. If you have problems compiling with errors that some types are not defined try opening xtensa-lx106-elf/xtensa-lx106-elf/sysroot/usr/include/c_types.h and replace #if 0 near the top with #if 1.

Get esptool

Some projects use esptool, which is something completely different as esptool.py and which is not installed by esp-open-sdk. You can get esptool here:

    maybe this belongs to changes in eagle.app.v6 ???

    _EDIT:_

    i have checked eagle.app.v6 files - found nothing special, so i think there is something with changed binary files

  • IoT  Firmware Websocket

    IoT Firmware Websocket "freezes" on frame segmentation at TCP level

    Attached oliiot.tcpdump.zip is a tcpdump from web socket session to one of your devices. After the HTTP handshake a TCP packet is send with 6 bytes - the header of a websocket frame, then another TCP packet is sent with the playload. Your client fails to acknowledge this packets and then some re transmission happens and practically no communication happens. As TCP is stream oriented protocol it is perfectly posible to receive every byte in a message in separate TCP packet and this should not break your "server"

  • ESP8266-EVB EMI noise

    ESP8266-EVB EMI noise

    I encountered some odd behaviour with the EVB. I mounted an http server on the ESP8266 ( javascript thanks to Espruino), and I tried to switch the relay state everytime a client connects to the server (thus, giving me a audible debug info). The case happened, where the ESP reseted by itself after the relay state changed. I experienced this many times. I think it may come from the electro-magnetic field created by the relay inductor, which may be important enough to cause electrical errors on the ESP side. Does anyone experienced the same behaviour?

  • IoT Firmware: Default config settings after complete flashing

    IoT Firmware: Default config settings after complete flashing

    When ESP is complete flashed (also blank.bin and esp_init_data_default.bin) there is different configuration of softAP & station which is stored by ESP SDK than when you press long button and restore_defaults occurs.

    Is there a way to detect initial ESP settings in user_main to be overriden by restore_defaults (which works better) not only with long-button press?

    Best Regards

  • Togle mode for relay

    Togle mode for relay

    Hi, does it possible to have 3-th state for relay "toggle" , which should switch it "on" and after a while switch back to "off". The goal is to have "button" like behavior with only one HTTP request . Now it is possible with two separated requests.

    it is possible to add webserver/websocket port config in web app

    It will usefull to add way to change default port from 80 to another one... Becuase host server/IoT server in some cases may use it for another app and board is not able to connect..

    I noticed some troubles working with softAP; to connect my comp to softAP: connected and immediately disconnected. station: 00:27:10:81:40:f4 join, AID = 1 station: 00:27:10:81:40:f4 leave, AID = 1 rm 1 add 1 aid 1 station: 00:27:10:81:40:f4 join, AID = 1 station: 00:27:10:81:40:f4 leave, AID = 1 rm 1 add 1 aid 1 station: 00:27:10:81:40:f4 join, AID = 1 station: 00:27:10:81:40:f4 leave, AID = 1 rm 1 etc.....

    I upgraded to new SDK and it may be much better. Just copied SDK files to working folder, except "makefile".

    HTML page it's not show in web Server

    Hi, i have a simple problem but to me it's being so dificulty to resolve. It's start recently, i've nerver had tbis problema before, when I connect in NODEMCU web Server in my web (192.168.0.114, for example), the page that i've created in program doesn't show, follow the code bellow:

    Note: The download was a succes and I already updated de NODEMCU firmware

    `#include <ESP8266WiFi.h>

    const char* ssid = "ssid"; const char* password = "password";

    WiFiServer server(80);

    void setup() { Serial.begin(115200); delay(10);

          Serial.print("Connecting to ");
          Serial.println(ssid);
    
          WiFi.begin(ssid, password);
    
          while (WiFi.status() != WL_CONNECTED) 
          {
              delay(500);
              Serial.print(".");
          }
    
           Serial.println("");
           Serial.println("WiFi connected");
    
           server.begin();
           Serial.println("Server started");
           Serial.println(WiFi.localIP());
    

    }

    void loop() { WiFiClient client = server.available(); if (!client) { return; }

        Serial.println("new client");
        while(!client.available())
        {
             delay(1);
        }
    

    String req = client.readStringUntil('\r'); Serial.println(req); client.flush();

    String buf = "";

    buf += "HTTP/1.1 200 OK\r\nContent-Type: text/html\r\n\r\n\r\n"; buf += "<html lang="en"><meta name="viewport" content="width=device-width, initial-scale=1, user-scalable=no"/>\r\n"; buf += "ESP8266 Web Server"; buf += ""; buf += ""; buf += "

    "; buf += "\n";

    client.print(buf); client.flush();

    Serial.println("Client disonnected"); }`
