5 months ago I've made some modifications but I'm still having issues. I embedded the certificate and set the size for the certificate; without it, it causes a core panic. Now, I'm receiving an error related to the certificate. This is my current code. Do you have any suggestions on why it might not be working or help for debugging?
#include "esp_log.h"
#include "mqtt_client.h"
#include "nvs_flash.h"
static const char *TAG = "MQTT_EXAMPLE";
esp_mqtt_client_handle_t client;
extern const uint8_t emqxsl_ca_crt_start[] asm("_binary_emqxsl_ca_pem_start");
extern const uint8_t emqxsl_ca_crt_end[] asm("_binary_emqxsl_ca_pem_end");
const size_t emqxsl_ca_crt_size = emqxsl_ca_crt_end - emqxsl_ca_crt_start;
static esp_err_t mqtt_event_handler_cb(esp_mqtt_event_handle_t event) {
switch (event->event_id) {
case MQTT_EVENT_CONNECTED:
ESP_LOGI(TAG, "MQTT_EVENT_CONNECTED");
esp_mqtt_client_publish(client, "test", "This is a test message", 0, 1, 0);
break;
case MQTT_EVENT_DISCONNECTED:
ESP_LOGI(TAG, "MQTT_EVENT_DISCONNECTED");
break;
default:
break;
}
return ESP_OK;
}
static void mqtt_event_handler(void *handler_args, esp_event_base_t base, int32_t event_id, void *event_data) {
esp_mqtt_event_handle_t event = (esp_mqtt_event_handle_t) event_data;
mqtt_event_handler_cb(event);
}
void mqtt_app_start(void) {
const esp_mqtt_client_config_t mqtt_cfg = {
.broker = {
.address = {
.uri = "mqtts://b0a3ea3c.ala.eu-central-1.emqxsl.com:8883",
},
.verification={
.certificate=(const char *) emqxsl_ca_crt_start,
.certificate_len=emqxsl_ca_crt_size
}
},
.credentials={
.username="test",
.authentication={
.password="123"
}
}
};
client = esp_mqtt_client_init(&mqtt_cfg);
esp_mqtt_client_register_event(client, MQTT_EVENT_ANY, mqtt_event_handler, client);
esp_mqtt_client_start(client);
}now i get this

General issue report
I'm trying to connect mqtt to emqx serverless broker. this is my code
(I modified some characters to be safe) When I put mqtts:// I get this error Guru Meditation Error: Core 0 panic'ed (LoadStoreAlignment). Exception was unhandled.

And if I remove the mqtts:// It won't crash but it doesn't connect mqtt_client: Error parse uri = Any ideas how to fix this?
