esp8266's Introduction

README

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:

https://github.com/tommie/esptool-ck

or here:

esp8266's Issues

What's the purpose of bringing out SD_CLK to SD_CMD? (EVB board)

The EVB board brings out (on the board header) the GPIO 6 to 11 (SD_CLK to SD_CMD) but, if I understand correctly, they cannot be used without crashing the running program.
Am I wrong? Can they be used someway?
Thanks

Add wifi client mode & config

Hi,
it's about esphttpd
Could you please add possibility for WIFI config and connect to an existing WIFI AP/router?

RX and TX pin are messed up

In the ESP8266EX-how-to-update-firmware.pdf you write:

The connections are easier if the board has male UEXT connector (like ESP8266-EVB). The important part
here is to connect the GND of the cable to the GND pin (#2) of the UEXT connector. Then TXD of the
cable to RXD of the UEXT (#4). Finally, RXD of the cable to TXD of the UEXT (#3).

but in the board's schematic , MOD-WIFI-ESP8266-DEV, hardware revision A and B, UEXT-PIN-4 is connected to TXD and UEXT-PIN-3 is connected to RXD.
So you have already crossed the RX-TX in your boards.
Please provide a correct description because there is a confusion.

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.

WEBCLIENT - no request freeing from list

I encountered some problems while POSTing data using WEBCLIENT; I tried to send data to thingspeak.com in cloud (of course data format is different than Olimex event format), PUT and POST are supported, not websockets.
There is no request freeing from the list which may cause memory leak.
Thingspeak responds using chunked response (at least two messages for response), so for proper response handling its needed to collect all messages.
There is also trouble when to many requests is triggered, limitation of ESP library. In this case function "espconn_connect" returns error and no "webclient_connect" callback is fired - also no freeing of requests.

I fixed troubles in my for., commit: https://github.com/mikexmas/ESP8266/commit/4bfabe9c350430285199be070363cb6b4d9ca151

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..

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"

Add Serial.read and Serial.available

It will be great if you can add the missing Serial.read and Serial.available functions to https://github.com/OLIMEX/ESP8266/blob/master/arduino_style/arduino/arduino_serial.c.

Conection betwen ESPs

I'd like to connect two ESPs, one of their is the Access point, the other is the client.
In the access point a have an out, his ip is the default of esp (192.168.4.1), i need with the client esp send an url like 192.168.4.1/led_on to turns the led on. I tried something but doesn't work. Someone could help me ?

MQTT example must be updated with changes to PubSubClient

In ESP8266/Arduino IDE/Relay-Control-MQTT/firmware/relay-mqtt.ino
there were changes to PubSubClient and especially constructor etc.
Please find attached updated INO file.

Status/event Messages: field "device" to fill with host name

Currently status/events messages has device field constant ESP8266, which means nothing:
{"Device" : "ESP8266", "Status" : "Authorization success"}

I suggest to put in some usefiull information, like hostname:
{"Device" : "LivingRoomThing", "Status" : "Authorization success"}
maybe wifi_station_get_hostname()

I've made a simple OpenHub binding and hostname gives much more information than constant.

WebClient.webclient_recv - Finishing chunked message hotfix

Sorry my bad for chunked messages.
Last chunk of chunked messages is "0\r\n", this is correct handled, but we have to set OK flag in receiver state machine to proper free request.
So please add:
request->response_state = WEBCLIENT_RESP_STATE_OK
in line 454
Complete lines:

    // Check if header && not chunked
    if (request->response_state == WEBCLIENT_RESP_STATE_WAITCHUNK) {
        if ((char *)os_strstr(pData, "0\r\n") == pData) {
            request->response_state = WEBCLIENT_RESP_STATE_OK;
            is_close_conn = true;
        }
    } else {

memcpy in fnc jsonparse_object_str copies 1 byte to much

Copiing value os_memcpy(dst, parser->json + pos - 1, len) in fnc jsonparse_object_str causes to copy +1 byte: includin ending "}".
{"key": value}
result in *dst: "value}"
correct result in *dst: "value"

Please check.

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

webpages.espfs has zero size

Everything is prepared for flashing esphttpd example instead of webpages.espfs

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";

Compile with SDK 2.1.0

What to change in order to make it compile with the latest SDK version? (2.1.0)

ESP8266 as Eagle component

Before I do it myself, I'm wondering does anybody already create this module as an Eagle component (device/package/symbol) to use it in other Eagle projects?

Tho functions move into flash instead of RAM

Is there any special reason to have following two fncs in RAM ?
user_config.c/config_response
user_webclient.c/webclient_host_check

I stray of RAM iram1_0_seg since SDK 1.5.3.

Change Makefile or README for examples

Good Day

I was testing my MOD-WIFI-ESP8266-DEV module and when flashing I had an error because the makefile uses esptool.py default baudrate (115200) but the MOD-WIFI-ESP8266-DEV, or at leats the ones I got work at 58200 in UART mode. I am not issuing a pull request because I don't know how you would like to address this problem.

Kind regards

Enhancement: Upgrade SDK to 1.5.1 (16.1.2016) (IoT Firmware)

I noticed some troubles working with softAP; to connect my comp to softAP: connected and
immediately disconnected.

etc.....

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

after commit SDK 2.0.0 IoT Firmware won't to compile

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

WPA2-PEAP Support

Hi :)
Did you success in connecting to a WPA2-PEAP with the new sdk V2.0.0?
I'm following Gidrix's sketch (esp8266/Arduino#2595) that it follows SDK Documentation flow, but my ESP8266-07 doesn't connect to eduroam (WPA-PEAP MSCHAPv2 network).

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?

Webserver does not respond after reconnect

In latest version I notified webserver troubles, when I make reconnect to device, first time webserver works ok, but after recconect not anymore; web server is not responding.
