This crash happens when I added file download function, but I hasn't found an error. Global variables remaining 36% of RAM, but all temp String variables are freed after finishing function automatically. So chunk server sending is collecting a much of junk?
I think that this can happen when converting char to char*. The read function returns a char and at the end of c-strings it should always be null and when converting it is not. Perhaps there is an error in this

I am trying to connect to HiveMQ MQTT Broker from my ESP8266, 2 months ago, this code works fine, but now, when I implement more features, the code run with a lot of Exceptions. Sometimes, Exception (28), I'm newbie in this fields and don't know the way to handle it, thanks for your helps.

I expect to a successful and stable connection to MQTT Broker
I have a project using MQTT-SN protocol, I use this https://github.com/S3ler/arduino-mqtt-sn-client as my MQTT-SN Client (I'm Using nodeMCU same as Arduino ESP8266) , my MQTT-SN Gateway use paho.mqtt-sn.embedded-c on my laptop and for my broker I use Mosquitto on my laptop too
this is the code for the MQTT-SN client
#include <ESP8266WiFi.h>

}
and this my MQTT-SN Gateway look, I can only connect and subscribe, I can't Publish or change my clientID
I already try to fix with https://github.com/S3ler/arduino-mqtt-sn-client/issues/3 but still I can't publish and I can only subscribe even my clientid won't change like I declared on my code
I don't know what's wrong with it,Can someone tell me what's wrong with my code?
Edit:
This is what it look like in my Arduino IDE Terminal, Someone know what is the error? or what is the problem that keep me can't publish?

Is anyone know what the error mean? Please tell me and Thank You
Thank you for all, but i already fix my problem it seem there is a wrong code in the library and you must change it, right now i'm doing fine doing some publish
I have been trying to encode a string using Nanopb library on NodeMCU and publish it using AzureMQTT.
On testing individually, both Nanopb and Azure work just fine. However, Integration of both in one sketch gives me errors.
void loop(){
uint8_t sMsg[512];
gestures data;
char *msg = "aaaaaaaaaaaaaaaaaaaaaaaaa";
strcpy(data.values,msg);
Serial.println("done with strcpy");
pb_ostream_t buffer = pb_ostream_from_buffer(sMsg, sizeof(sMsg));
if (!(pb_encode(&buffer, gestures_fields, &data))) {
Serial.println(F("Encoding failed"));
Serial.println(PB_GET_ERROR(&buffer));
return;
}
else
{
Serial.println("enterd else");
Serial.println((char*)sMsg);
client.run();
if (client.connected()) {
Serial.println("connected");
String payload = "{\"DeviceId\":\"" + String(DEVICE_ID) + "\", \"data\":" + (char*)sMsg + "}";
Serial.println(payload);
client.sendEvent(payload);
Serial.println("Published message!");
}
}
Serial.println("Done with loop");
}
The Serial output is as below:
entered if
done with strcpy
enterd else
aaaaaaaaaaaaaaaaaaaaaaaaa?z[#t/⸮?⸮⸮⸮?⸮⸮⸮?⸮⸮⸮?⸮+⸮?⸮⸮⸮?$⸮?
Done with loop
If observed, the client.connected() is returning false, hence, the message is not being published.
Also, sometimes, at client.run() there's a stack error:

It seems you may be overflowing your stack, i.e. running out of space allocated for local variables. When either of the libraries run alone, there is enough space, but when combined it runs out.
A simple way to fix this would be to change this large variable to static allocation:
uint8_t sMsg[512]; // Allocated on stack area
static uint8_t sMsg[512]; // Allocated separately
What static does is that it reserves a section for the variable for the whole duration of the program, instead of trying to fit it in the small dynamic area of the stack.
It is also possible to increase the stack size. On Arduino ESP8266 SDK, this seems to be done by modifying CONT_STACKSIZE in cores/esp8266/cont.h.
I'm using pubsubclient library.
I used this function to connect to mosquitto broker which using mosquitto-auth-plug with JWT authentication.
void reconnect() {
// Loop until we're reconnected
while (!client.connected()) {
Serial.print("Attempting MQTT connection...");
// Attempt to connect
String red_token = "eyJhbGciOiJIUzUxMiJ9.*****";
String deviceTopic = "outTopic";
//My token length is 205 characters
//client.connect(strDeviceId.c_str(), red_token.c_str(),"pass", deviceTopic.c_str(), 0, false, CMD_OFF_LINE)
bool result = client.connect("newClientIdMCU",token,"pass", deviceTopic.c_str(), 0, 0, "offline");
delay(2000);
if (result) {
Serial.println("connected");
// Once connected, publish an announcement...
client.publish(deviceTopic.c_str(), "hello world");
} else {
Serial.print("failed, rc=");
Serial.print(client.state());
Serial.println(" try again in 5 seconds");
// Wait 5 seconds before retrying
delay(5000);
}
}
}
This exception occurs when client.connect called:
Attempting MQTT connection...

On broker log "New connection...." but Sending CONNACK to clientId (0, 0) can't send.
What could be problem?
I change pubsubclient.h file lib from:
// MQTT_MAX_PACKET_SIZE : Maximum packet size
#ifndef MQTT_MAX_PACKET_SIZE
#define MQTT_MAX_PACKET_SIZE 128
to
// MQTT_MAX_PACKET_SIZE : Maximum packet size
#ifndef MQTT_MAX_PACKET_SIZE
#define MQTT_MAX_PACKET_SIZE 256
it works.
I need to acquire some points' coordinates (represented by variables xCoord and yCoord) and set to 1 the associated positions in matrix scan_image. It may happen that a point's coordinates are outside matrix's dimensions, so scan_image needs to be resized before setting point's associated position in matrix to 1.

I tried many options to modify scan_info's dimensions (you'll find them in comments) in case denoted as CASE 3, but everytime I get a bad memory error:
