Esp32 support

[rickgrael]

Does this lib support ESP32? I'm trying to connect to a server hosted in heroku. This server container a MOSCA broker, but pubsubclient does not support ws: connection.

Sorry I don't know, I used it for one project only.

Yes, it works with ESP32! Here is tested code, that works with ws and wss:

#include <PubSubClient.h>
#include <WiFiClientSecure.h>
#include "WebSocketClient250.h"
#include "WebSocketStreamClient.h"

/* MQTT credentials */
const char* mqtt_host = MQTT_HOST;
const int   mqtt_port = MQTT_PORT;
const char* mqtt_path = MQTT_PATH;
const char* mqtt_id   = MQTT_ID;
const char* mqtt_user = MQTT_USER;
const char* mqtt_pass = MQTT_PASS;

/* create an instance of PubSubClient client */
WiFiClientSecure espClient;
WebSocketClient250 wsClient(espClient, mqtt_host, mqtt_port);
WebSocketStreamClient wsStreamClient(wsClient, mqtt_path);
PubSubClient mqtt_client(wsStreamClient);

void mqtt_init(void) {
  // don't check sign chain
  espClient.setInsecure();
}

void mqtt_connect() {
  /* connect now */
  if (mqtt_client.connect(mqtt_id, mqtt_user, mqtt_pass)) {
    Serial.println("mqtt connected");
  }
}

Great news 👍 could you tell me what version of esp32 board (arduino ide?) are you using ? You can also have a look to https://github.com/clysss/WebSocketStreamClient make caution to buffer size in websocket.h just received a proposed update of this file : https://github.com/arduino-libraries/ArduinoHttpClient/issues/68#issuecomment-1021150686

Hi, @clysss! I've used it with TTGO T-Call V1.3 ESP32 board in Platformio IDE. Here is the project config:

[env:esp32]
platform = espressif32
board =  esp-wrover-kit
framework = arduino
monitor_speed = 115200
upload_protocol = espota
lib_deps = TinyGSM
           PubSubClient
           ESP32Ping
           WiFiClientSecure
           ArduinoHttpClient

[clysss]

Thanks:) Is it 2.0.2 version of https://github.com/espressif/arduino-esp32 ?

This one: https://github.com/platformio/platform-espressif32/releases/tag/v3.4.0

[clysss]

Hmm yes:) of course, sorry! Thansks to have point me the difference, i'll have to try with platform io :) perhaps to move to..

May i ask you to try to compile using classical socket and not xxx250 like in the sample of my fork?

@clysss I have proposed this ws tx buffer size redefinition in order to make your https://github.com/clysss/WebSocketStreamClient works with bigger messages. I confirm that I have used platform io and esp32 target and it works after increasing this buffer.

[clysss]

Thanks a lot Pablo:) with your information, I've been able to correctly make my board working (my issue was not on websoketstream but a bad return after a publish...) with last firmware :)

Any tips to see why it's not working? I just don't get a connection

[clysss]

Use open tool to verify the websocket / at least your browser. Firewall?

I can connect no problem with another client.

Tried with both:

WiFiClientSecure wiFiClient; WiFiClient wiFiClient;

Does the host need to have ws:// specifed ?

currenly i have the following

static const char *host = "192.168.100.201";

Host is running on local lan and works fine with other websocket clients.

[fabltd]

@clysss I see in wireshark 400 bad request.

Somehow WS fails. I have no idea why

[clysss]

i declare something like this : WiFiClientSecure wifiClient; WebSocketClient wsClient(wifiClient, "toto.ccc.com", 443); WebSocketStreamClient wsStreamClient(wsClient, mqttPath); PubSubClient MQTTClient(wsStreamClient);

@clysss

Yes thats how i did it. It just refuses to connect to emqx:

WiFiClient wiFiClient;
WebSocketClient wsClient(wiFiClient, host, port);
WebSocketStreamClient wsStreamClient(wsClient, path);
PubSubClient client(wsStreamClient);

[clysss]

And you change the buffer size?

If the websocket is supposed to be ssl-ed, use wificlientsecure...

No more ideas, sorry
