Exception 28

[gnkarn]

hi , i m experiencing this type of problem on my program running on node mcc 1.0 im using your code , as it has the capability to explicitly manage the different callbacks better than on the original library .

this is the error i see

[SIoC] Connected to url: /socket.io/?transport=websocket [SIoC] trigger event connect

Exception (28): epc1=0x40207324 epc2=0x00000000 epc3=0x00000000 excvaddr=0x00000000 depc=0x00000000

ctx: cont sp: 3fff5e40 end: 3fff6300 offset: 01a0

if i comment out the web socket begin line in my code , the problem goes away, then i assume it may have to do with the connection process to the server .

the server , is a Heroku server .

i have added , Yield(), and delay in the connect call back function , but with , no effect , i think that the code exits in the library , and it never reach, my callback function.

any hint to help my debugging is much appreciated ,

more info with the server disconnected , the error is [SIoC] Disconnected! [SIoC] trigger event disconnected

Exception (28): epc1=0x40207346 epc2=0x00000000 epc3=0x00000000 excvaddr=0x00000000 depc=0x00000000

ctx: cont sp: 3fff5fb0 end: 3fff6330 offset: 01a0

with the server connected , the error is Port open [SIoC] Connected to url: /socket.io/?transport=websocket [SIoC] trigger event connect

Exception (28): epc1=0x40207324 epc2=0x00000000 epc3=0x00000000 excvaddr=0x00000000 depc=0x00000000

could you post your program code ? it seems like it has some problems finding the callbacks for connect and disconnect events. I have not tested the library with node MCU though..

thanks for the reply

this is on the setup : herokuWs.begin("app-gnk-p5js.herokuapp.com" , 80); // for socket.io client library

herokuWs.on("msgFromServer", wsVideoEvent);
herokuWs.on("time", wsTimeEvent);
herokuWs.on("connect", wsConnectEvent); 
herokuWs.on("disconnected", wsDisconnectedEvent);

this is , in the loop

herokuWs.loop(); // handles Heroku socket.io loop herokuHeartBeat(); // send HB to Heroku WS server

and this on the callbacks

void wsVideoEvent(const char payload, size_t lenght) { // this to receive a message from the Heroku Server USE_SERIAL.printf("[%u] Received from Heroku (video): %s\n", payload); String text = String((char )&payload[0]);

// if current efect is video continue else jump

if (text.startsWith("Y")) {      // video message
    String xVal = (text.substring(text.indexOf("Y") + 1, text.length()));

}
//parse JSON objet

// transfer objet to ledMatrix

//end

// send message to client
// webSocket.sendTXT(num, "message here");

// send data to all connected clients
// webSocket.broadcastTXT("message here");

}

void wsTimeEvent(const char * payload, size_t lenght) { yield(); char text = payload[0]; USE_SERIAL.printf("[%u] Received from Heroku (Time): %s\n", text); }

void wsConnectEvent(const char * payload, size_t lenght) {

yield();
char text = payload[0];
USE_SERIAL.printf("[%u] Received from Heroku (connect): %s\n", text);

}

void wsDisconnectedEvent(const char * payload, size_t lenght) { char text = payload[0]; USE_SERIAL.printf("[%u] disconnected from Heroku (disconnected): %s\n", text); }

i understand i have to make proper treatment of the payload , it is working fine on my javascript client, but here i need to understand how to decode the json object passed by reference with the Json library ( still struggling ) with that one too

full code , is here : https://github.com/gnkarn/Funky_Control8266-jqm/blob/Heroku%26p5js/Funky_Control8266-jqm/LEDWebsockets.h

are you still having the problem? Did you try anything yet?
