asynctcp's Issues

Impossible to build with ESP32 1.0.1 and AsyncTCP 1.0.3

Hello,

I'm currently facing to this issue when trying to bulked a simple WebSocket example on my ESP WEMOS LOLIN 32.

I had a look on several issues reported, all of them said to compile AsyncTCP 1.0.3 with ESP32 1.0.1, but is seems that there is a another problem though.
Any idea to make it works?

Server Show Client Connected Even if Client Loses Power

When a client connects and sends data, everything works normally. However, if the client connects and loses power or just connects to another AP while the connection is open, no notification of the client disconnecting exists.

Even if you check if clients[N]->connected() it will return true even if the client is unplugged.

Is there a way to get a disconnection message when the client disassociates from WiFi even if the connection is still open?

Many Tanks

Great development!
it works as expected, tested on my demo project: https://www.youtube.com/watch?v=kZd_KVBMzko

WDT triggered by plain FS listing

Hello,

SPIFFS contains only CSS,
all relevant data is on SD Card.

When there is certain amount of files in one dir (in my case around 170) on SD Card, plain 'ls dir' triggers WDT -

Rebooting...

The same code works fine on 'classic' WebServer.
Relevant part of the code is here ->

String listDirectory( File path, bool jsonFlag ) {

  String linkName;
  int numPic = 0;
  String strJSON = "[";

  if( path.isDirectory() ) {
    File file = path.openNextFile();
    while( file ) {
      linkName = String( file.name() );
      if( strJSON != "[" ) {
        strJSON += ',';
      }
      strJSON += "{\"type\":\"";
      strJSON += ( file.isDirectory() ) ? "dir" : "file";
      strJSON += "\",\"name\":\"";
      strJSON += String( file.name() ).substring(1);
      strJSON += "\"}";
      file.close();
      file = path.openNextFile();
      numPic++;
    }
  }
  strJSON += "]";
  return strJSON;

}

bool loadFromSDCard( AsyncWebServerRequest *request ) {

  String dataType;
  String webText;
  String path = request->url();

  File dataFile = SD_MMC.open( path.c_str() );

  if( !dataFile ) {
    return false;
  }

  if( dataFile.isDirectory() ) {
//    webText = listDirectory( dataFile );
//    request->send( 200, "text/html", webText );
    webText = listDirectory( dataFile, true );
    request->send( 200, "application/json", webText );
    dataFile.close();
    return true;
  }
  if( path.endsWith( ".jpg" ) ) {
    dataType = "image/jpeg";
    // request->send( SD_MMC, path.c_str(), String(), true ); // new window - download
    request->send( SD_MMC, path.c_str(), dataType );
    dataFile.close();
    return true;
  }

  return false;

}

void asyncHandleNotFound( AsyncWebServerRequest *request ) {

  String path = request->url();
  String dataType = "text/plain";
  String webText;

  int lastSlash = path.lastIndexOf( '/' );
  String fileName = path.substring( lastSlash, path.length() );

  bool fileSPIFFS = false;
  if( fileName.endsWith( ".css" ) ) {
    dataType = "text/css";

    return;
  }

  webText = "\nNo Handler\r\n" + webText;
  request->send( 404, "text/plain", webText );
  DBG_OUTPUT_PORT.println( webText );

}

void initAsyncWebServer( void ) {

  asyncWebServer.onNotFound( asyncHandleNotFound );

  asyncWebServer.begin();

}

example required

is there any usage examples for this library? arduino
thanks very much.

AsyncClient::add() never returns

Hi,
I have issue with AsyncClient::add() - it never returns, when adding only 2 bytes.
I'm actually trying to modify https://github.com/marvinroger/async-mqtt-client to work with ESP32, but it fails right at the beginning in the onConnect callback where it tries to assemeble the packet.

Please do you have any clue what goes wrong or where to look?

compilation error on linux

Hi
I have recently used this library on windows 10 together with ESPUI and I was quite happy with it
But i had to move my whole work to linux(parrot OS) and after installing arduino 1.8.7 and esp32 package, I started with gui example. It didn't work. Here's the error message:
Arduino: 1.8.7 (Linux), Board: "ESP32 Dev Module, Disabled, Default, QIO, 80MHz, 4MB (32Mb), 921600, None"

As a sidenote, since I had to do my work on a flash memory and persistent partition, I had no choice but doing EVERYTHING as a root user.
Arduino ide cannot work without it(Serial usb access) and even arduino playground solution for that cannot help, since it is a live user

Missing dependency?

My project's travis build (https://travis-ci.org/bofh69/AiLight/builds/274342483) started to fail today:

In file included from .piolibdeps/AsyncTCP_ID1826/src/AsyncTCP.cpp:24:0:
.piolibdeps/AsyncTCP_ID1826/src/AsyncTCP.h:28:29: fatal error: freertos/semphr.h: No such file or directory
#include "freertos/semphr.h"
^
compilation terminated.

Shouldn't there be a dependency on the freetos library from this library?

Thread safety/multicore and race conditions

My debugging seems to indicate that AsyncTCP is not thread/multicore save on the ESP32. I.e. one or more of the onError/onDisconnect/onData etc events will run parallel with the main core on the ESP32 and can therefore cause race conditions. I solved this by wrapping all events in a mutex and since then the code has been stable. More background.

I was wondering if this was by design? If so it might be good to mention it in the README/code comments.

I think this might be the cause of: me-no-dev/ESPAsyncWebServer#324

Using with Arduino IDE

hi, I am trying to use this library with Arduino IDE but facing some difficulty in finding this in the libraries ( using library manager ). ESP32/Arduino IDE is new to me so are there any steps I can follow to install this library?
My ultimate aim is to be able to use this library: https://github.com/me-no-dev/ESPAsyncWebServer and this library requires AsyncTCP.

Thanks a lot, appreciate any pointers.

Slow speed & corruption, am I doing something wrong?

I have a program that reads 60 bytes of info from an IMU (gyroscope, accelerometer, compass) and sends it out WiFi by TCP. I'm having trouble getting the throughput I need and I'm wondering if I am doing something wrong or if this is a limit of the hardware?

Minus all the IMU reading stuff, the main loop looks something like

void loop()
{
int
loop_start; // Time in micros at top of loop

loop_start = micros();
if(loop_start < next_report)
return;
next_report = loop_start + REPORT_TIME;

// Read IMU and put 60 bytes of data into tempbuf

  telemetryClient->write((char*)tempbuf, 60, ASYNC_WRITE_FLAG_COPY | ASYNC_WRITE_FLAG_MORE);

}

Run this at 100hz and it works fine, at 1000hz (still less than 1m bits/sec) and I get all kinds of data corruption.

Do you think I should be able to send data this fast on ESP32? Anything I can do to make it work? I have tried using add/send and have the same problems. Also tried write with the default flags.

The data doesn't have to go out immediately, it can be buffered up till we have a max-size packet (no nagle algorithm needed).

error: 'xTaskCreateUniversal' was not declared in this scope

Trying to use the library for ESP32 OTA support. Newest version throws an exception that did not exist in version 1.0.3.

.piolibdeps\AsyncTCP_ID1826\src\AsyncTCP.cpp: In function 'bool _start_async_task()':

SSL support?

I was under the impression I would be able to use ssl with ESPAsyncWebServer on esp32, however as this library doesn't support ssl (whereas it's esp8266 counterpart does) it appears that's not possible?

It would be nice for this lib to be on par with the esp8266 version in terms of features to avoid surprises like this.

Is ssl support a feature that is likely to get implemented?

Using hostname on ESP32 fails to connect

When using mqttClient.setServer("myserver.lan", 1883) the connection fails on ESP32, on ESP8266 it works fine.

When using mqttClient.setServer(IpAddress(192, 168, 0, 1), 1883) it works fine.

The asyncmqtt library uses client->connect of AsyncTCP which I think fails

Correct use of ESP.reset() when using Async Libs?

Thanks for such a fantastic library. I have a question and have not been able to find an answer.

As far as I can work out, when using any of the Async libraries you should never use the delay(nn) function which I understand.

What I am unable to work out is what is the correct way to use the ESP.reset() function.
All examples I have found always seem to follow this (note that the delay times vary depending on where you find your example).

delay(3000);
ESP.reset();
delay(2000);

So with the idea that we can't use the delay() function, what is the correct way to do this?

AsyncClient::errorToString seems to be incorrect.

In comparing AsyncClient::errorToString to err_strerr in esp-idf/components/lwip/lwip/src/api/err,c, the error string for -8 is "Address in use." in err.c and "Connection aborted" in AsyncTCP and then -13 is "Connection aborted." in err.c and "Address in use." in AsyncTCP.

Can't compile with the latest ESP32 snapshot

Hi, seems, that the library can't be anymore compiled with the latest arduino esp32 code:

C:\RH\arduino-1.8.5\hardware\espressif\esp32\libraries\AsyncTCP\src\AsyncTCP.cpp:259:27: error: field 'call' has incomplete type 'tcpip_api_call'

 struct tcpip_api_call call;

                       ^

C:\RH\arduino-1.8.5\hardware\espressif\esp32\libraries\AsyncTCP\src\AsyncTCP.cpp:259:12: note: forward declaration of 'struct tcpip_api_call'

 struct tcpip_api_call call;

ipv6 support - small code change suggested.

Currently, the library will only bind to ipv4 addresses when used as a server. I've been doing some testing and discovered that a couple of small changes will allow the code to work with either ipv4 or ipv6 connections. Is this something worth creating a pull request for?

I haven't yet looked at making the same changes to connect() to support outbound connections to an ipv6
address, but that's also not hard I suspect, but would require an api change.

For anyone who's interested, the key change is to use IP_ADDR_TYPE_ANY instead of IP_ADDR_TYPE_V4 in server.begin(), and then bind to IP_ANY_TYPE a few lines later.

There are then a few places in the code where structures need to be declared const in tcp_api_call_t, and the definition of _tcp_bind.

I now have my esp32 happily responding to ipv6 web requests.....

unstable connection: disconnects, slow responses, lots of retransmissions

I'm struggling to get the lib working for a simple modbus master. I can't even connect to the server.
Wireshark shows a remarkable log:

Even though the ESP is already connected, it resends SYN. Also, it takes about 3 seconds before the ESP knows it has connected (wireshark show it about 3 secs sooner).

From time to time, I experience stranger errors like [E][AsyncTCP.cpp:571] _recv(): 0x3ffbb578 != 0x3ffbb120

Behaviour is the same for the main branch as the idf-update branch. The _recv() only appears at the idf-update branch.

Edit: when the _recv() error appears, there's no callback called, so my app also doesn't know it can move on. As a workaround I need to implement a timer myself.

ESP32 - Bind error:67 Ethernet wiznet5500 using Ethernet2.h library

Hi, I have an issue to make it work with ethernet Module W5500 using Ethernet2.h arduino library.
My board is a ESP32 conected via SPI to the W5500. By the way the W5500 is fully working and connected to my network.

With wifi connection everything work.
The error I am getting:
[AsyncTCP.cpp:1107] begin(): bind error: 67

I really don't know what that "67" means.
Any idea?
Regards.

Is AsyncTCP can replace WiFiClient client?

I want to GET parameters from a webserver. Currently I am using WifiClient to do that. Now I am using AsyncTCP to use my ESP32 as a websocket so I am wondering how to use AsyncTCP as a client.
String GetClient(String URL)
{
String line1="";
String SHHH="";
if (!client.connect(serverName, serverPort)) {
Serial.println("Host connection failed");
}
else {
URL.replace(" ", "%");
Serial.print("Requesting URL: ");
Serial.println(URL);
client.print(String("GET ") + URL + " HTTP/1.1\r\n" +
"Host: " + serverName + "\r\n" +
"Connection: close\r\n\r\n");
unsigned long startTime=millis();
while (!client.available()) {
if (millis() - startTime > 60000UL) {
Serial.println("request failed");
break;
}
}
while (client.available()) {
String line = client.readStringUntil('<');
line1 = client.readStringUntil('>');
ws.textAll(":"+line1);
Serial.println(line1);//Record CODE CREATED
if(line1.indexOf(',')==-1) {
SHHH=line1;
}

         }
          client.flush();
    }

return SHHH;
}

WDT on repetitive connection when distant server is slow to free conn or respond

Hello all,

I am using 16 esp32, sending POST to a small http server & receiving udp msg. I am getting an wdt on wifi core after some hours of processing, on some esp32.

version :
PLATFORM: Espressif 32 1.10.0,
arduino-esp32 v1.0.3
AsyncTCP 1.1.0

The situation :

I have a server sending every 10 sec a broadcast udp request to multiple ESP32 ( wemos d1 esp32). When the esp32 receives the udp request, it sends a tcp POST, with asynctcp, to the server.
Everything work fine with 3 esp32.
However, with 16 esp32, I got wdt after a few hours, on some device. I guess it's when the server is not fast enough to handle the requests at once.
The server is a simple java HttpServer. The UDP sender is a simple app in java sending the packet.

on the ESP, udp server is WiFiUDP, read in the main loop

void readUdpControl() {
  int count = udpControl.parsePacket();
  if (count) { 
    String buf = udpControl.readString();
    processNetControl(buf);
  }
}

in the following code, getWDPostInfo returns a arduinojson'ised' structure as string.

(the watchdog wording here is not linked with espressif wdt...

void watchDogAsync() {
  if (tcpClient) { // client already exists
    log("ASYNCTCP-Stooping: client already exists");
    return;
  }

  watchdogContent = getWDPostInfo().c_str();

  tcpClient = new AsyncClient();
  if (!tcpClient) { // could not allocate client
    log("ASYNCTCP-Stooping:  could not allocate client");
    return;
  }

  tcpClient->onError([](void *arg, AsyncClient *client, int error) {
    tcpClient = NULL;
    delete client;
  }, NULL);

  tcpClient->onConnect([](void *arg, AsyncClient *client) {

    client->onError(NULL, NULL);

    client->onData([](void *arg, AsyncClient *c, void *data, size_t len) {},
                   NULL);

    client->onDisconnect([](void *arg, AsyncClient *c) {
      tcpClient = NULL;
      delete c;
      Serial.println("Dis");

    }, NULL);

    tcpClient->write(watchdogContent.c_str());
    // tcpClient->stop();
  }, NULL);

  if (!tcpClient->connect(udpOTA.remoteIP().toString().c_str(), 23780)) {
    log("ASYNCTCP-Connect Fail");
    AsyncClient *client = tcpClient;
    tcpClient = NULL;
    delete client;
  }
}

Since everything works fine when using 3 devices, I guess the problem origin when using all my esp32 is my server not handling stuff quickly enough. But AsyncTCP should take care of this and not letting wdt'd.

How can I be assured asynctcp is using a timeout on all steps of the connexion ?

Unify the ESP32 and ESP8266 version.

My library works on both ESP32 and ESP8266, but I had trouble getting my project to reliably switch between using AsyncTCP and ESPAsyncTCP depending on the hardware (this was with platformio). In the end I decided to make AsyncTCP also work/compile on ESP8266 hardware. If you are interested the relevant files/changes can be found here:

https://gitlab.com/BlackEdder/painlessMesh/blob/tcp_locking/src/AsyncTCP.h
https://gitlab.com/BlackEdder/painlessMesh/blob/tcp_locking/src/AsyncTCP.cpp

Support for ESP-IDF

Is there any support for AsyncTCP or ESPAsyncWebServer in ESP-IDF? if no can we use a C++ library like this in ESP-IDF?

ETH support

Can the lib be used with ETH on the ESP32 instead of WiFi?

incompatible with new SDK 2.1

unable to build with latest commits in Arduino for SDK 2.1 - I conclude this is the reason.

Please see the log output here:

client connection timeout.

Hello,
I am using the library to connect to my solar inverter and collect data.
It all works great except when the inverter is shut down and it is no longer connected to my network. aClient hangs and returns "Error : Address in use".
Is there a way I can set a connection time out?
I have tried running a timer after the connection attempt starts and calling aClient->close() when my timer runs out but the causes the esp to crash.
onTimeout is never called even when I use setRXTimeout or setACKTimeout .
Any help would be appreciated. Thanks

  if (!aClient->connect(InvAdd, InvPort)) {
    Serial.println("Connect Fail");
    AsyncClient * client = aClient;
    aClient = NULL;
    delete client;
  }

remoteIP() and remotePort() return only 0

When using remoteIP() and remotePort() to catch the connected client ip address provides only 0's.

Code:

AsyncWebServer server(80);
AsyncClient remoteclient;

// respond to GET requests on URL /heap
server.on("/heap", HTTP_GET, [](AsyncWebServerRequest *request){
Serial.println(remoteclient.remoteIP().toString());
Serial.println(remoteclient.remotePort());
request->send(200, "text/plain", String(ESP.getFreeHeap()));
});

Output:
0.0.0.0
0

Rest of my webserver code is running fine.

Using github version of:

AsyncTCP-master-24102017.zip
ESPAsyncWebServer-master-24102017.zip
arduino-esp32-master_v3.0-dev-899-g3a271a4a_19102017.zip
Arduino IDE 1.6.12 running on doitESP32devkitV1

Bug or are do I something wrong?

Changing priority of task

I tried to port my code from ESP8266 to ESP32 and became timing issues. Problem was that on the ESP8266 the requests were handled in the loop and not Async at any time. This caused timing issues in the rest of the logic which is critical for my application. I tried to fix that by suspending the AsyncTCP task but it didn't work exactly how i wanted.
Finally a hige difference made the change of the tasks priority.

Changing priority from 3
xTaskCreateUniversal(_async_service_task, "async_tcp", 8192 * 2, NULL, 3, &_async_service_task_handle, CONFIG_ASYNC_TCP_RUNNING_CORE);

to 1 fixed all my issues
xTaskCreateUniversal(_async_service_task, "async_tcp", 8192 * 2, NULL, 1, &_async_service_task_handle, CONFIG_ASYNC_TCP_RUNNING_CORE);

Now my code runs reliable without any noticeable impact by handled requests.

So is there a reason that by default the priority is set to 3?

ESP32 simple Webserver hangs network connection completely

I posted a closer description here, but I doubt it's the right place:
espressif/arduino-esp32#2267 (comment)

Basic webserver fails immediately when putting synchronous requests to it using
a webside which contains some small pictures. WLAN or LAN makes no difference.
(Arduino+AsyncWebserver).

For me it "feels" like an interfacing issue to lwIP or even a problem in lwIP.
Are you able to tell me how to continue debugging?

error on send large data

I used to send jpg ,it works fine on about 5k byte size,but over 5k the picture have some part invisible and have notice like : "Low-level netif error"

onDisconnect sometimes doesn't fire (on hold)

I'm using AsyncMqttClient with relative low timeouts (10 seconds).
Sometimes the onDisconnect callback doesn't fire, always after this message:

[W][AsyncTCP.cpp:632] _poll(): rx timeout 4

Subsequently, my esp thinks it's connected and doesn't reconnect. The AsyncMqttLib relies on onPoll to check the connection. As this callback is called only when there is a connection, it stops checking completely.

Release tags

Hi, as I see, there are no release tags and it is difficult to roll back to a specific release without diving into commit logs.

With the recent update to esp-idf that introduced problems with mesh (non-)working (espressif/esp-idf#2916, espressif/esp-idf#2915), I wanted to do roll-back but I couldn't figure out which version should I check out.

The library isn't working with latest version of Arduino esp-32.

ESP32 rebooting when file serving from SPIFFS

Hi all!

When I use serveStatic(), it triggers watchdog timer and reboot device when I serve large file (~25kB).
JSON responses are handled correctly.
ESP32 works in WIFI AP mode.

My serverUp code:

  
  esp_wifi_set_ps (WIFI_PS_NONE);
  server.serveStatic("/", SPIFFS, "/").setDefaultFile("index.html");  // Обработчик запроса домашней страницы
  server.serveStatic("/gz/css", SPIFFS, "/gz/css");
  server.serveStatic("/gz/js", SPIFFS, "/gz/js");
  server.serveStatic("/public", SPIFFS, "/logs");
  //server.serveStatic("/settings.json", SPIFFS, "/settings.json").setAuthentication(auth_username, device_key);
  server.on("/set_track_times", HTTP_POST, [](AsyncWebServerRequest *request) {
    saveTimeLimSets(request);
    req_millis = millis();
  });
  server.on("/file_list", HTTP_GET, [](AsyncWebServerRequest *request) {
    handleFileList(request);
    req_millis = millis();
  });
  server.on("/file_from_sd", HTTP_GET, [](AsyncWebServerRequest *request) {
    handleSDFileList(request);
    req_millis = millis();
  });
  server.on("/get_dev_data", [](AsyncWebServerRequest *request) {
    getDevData(dataObject.ts_now, request);
    req_millis = millis();
  });
  server.on("/get_tts", [](AsyncWebServerRequest *request) {
    request->send(403, "text/plain", "FORBIDDEN");
    req_millis = millis();
  });

  server.on("/op_status", [](AsyncWebServerRequest *request) {
    sendFinishCode(request);
    req_millis = millis();  
  });
  
  server.serveStatic("/config", SPIFFS, "/config.html");
  server.onNotFound([](AsyncWebServerRequest *request) {
    request->send(404, "text/plain", "Not found");
  }); //  Обработчик запроса несуществующей страницы

  //server.setRxTimeout(5000);
  //server.setAckTimeout(5000);
  //Serial.print("No delay: ");
//  Serial.println(server.getNoDelay() ? "true" : "false");
  server.begin();
}

WDT trigger by async_tcp when stressing TCP stack

Hi,

Using AsyncTcp in combination Asyncwebserver, timers etc, (on PlatformIO these days, upstream library/SDK), and had issues with stability when stressing the tcp stack,
I noticed great improvement with stability with last commit and i did some testing:

having ServerSide Events running (webapp) in a 250ms data update interval, walk away (client from ESP32), to increase WiFi distance and see get tcp stack struggling when getting near out of reach (as expected), and it recovers as soon it got in reach again. Great!
idem, but now data update interval set to 1ms, walk away (near) out of distance, but then the watchdog gets triggered. The watchdog timer is configured by me to 8 seconds.

The relevant part of the serial monitor:

E (350990) task_wdt: Task watchdog got triggered. The following tasks did not reset the watchdog in time:
E (350990) task_wdt:  - async_tcp (CPU 1)
E (350990) task_wdt: Tasks currently running:
E (350990) task_wdt: CPU 0: IDLE0
E (350990) task_wdt: CPU 1: IDLE1
E (350990) task_wdt: Aborting.
abort() was called at PC 0x400f5b33 on core 0

In issue 14 the watchdog is also mentioned, but that is of 7th may, and asyncTcp code had updates afterwards
A more recent but Similar report

I assume it is trying to tell me, that the AsyncTCP does not-, or fails to- reset the watchdog, in a stressful situation, not (easy) getting data out, and new data keeps coming in.

Getting Random crashes when connecting via TCP

I can't find a pattern to why this is happening. Sometimes it happens and sometimes it doesn't. When it does, the ESP32 freezes and restarts itself.

I'm using the the latest Arduino core (1.0.3 rc1) and IDF. ESPAsyncWebServer is also up to date.

Here is the trace:

How to restart ESP whenever I get this : "[W][AsyncTCP.cpp:896] _poll(): ack timeout 4" ?

Board: ESP32

Hello !
As per-title I would like to know if it's possible to restart the ESP whenever I get the following warning:

[W][AsyncTCP.cpp:896] _poll(): ack timeout 4

This basically means that the server timed-out and it can't be used. And the only method of restoring it is to manually reset the ESP.

Have tried current and prev git versions AsyncTCP && current and prev version of arduino-esp32 - results are the same. Any Idea how to fix it?

I'm using the latest IDE version 1.8.9 (but I had the same issue with v1.8.0) and selected either LOLIN D32 or ESP32 dev module

Error during compilation with newest arduino-esp32

WROOM -32
Arduino IDE

Until the last update espressif/arduino-esp32, there were no errors during compilation, and now the project is not compiled.
