Hallo,
I'm currently facing a problem with the bsec-Library and an ESP8266.
I started with the basic.ino script which seems to work, but after ~30min the ESP8266 crashes and reboots. Therefore I modified the script a little bit to print the free heap size. This shows that there is a memory leak and the ESP8266 crashes after it ran out of memory.
Is this a known problem and is there a fix for this?
I am using this version:
Arduino IDE: 1.8.13
bsec: 1.6.1480
esp8266 core: 2.7.4
#include "bsec.h"
extern "C" {
#include "user_interface.h"
}
// Helper functions declarations
void checkIaqSensorStatus(void);
// Create an object of the class Bsec
Bsec iaqSensor;
String output;
// Entry point for the example
void setup(void)
{
Serial.begin(115200);
Wire.begin();
iaqSensor.begin(BME680_I2C_ADDR_SECONDARY, Wire);
Serial.println(output);
checkIaqSensorStatus();
bsec_virtual_sensor_t sensorList[2] = {
BSEC_OUTPUT_IAQ,
BSEC_OUTPUT_STATIC_IAQ,
};
iaqSensor.updateSubscription(sensorList, 2, BSEC_SAMPLE_RATE_CONTINUOUS);
checkIaqSensorStatus();
// Print the header
output = "Timestamp [ms], IAQ, IAQ accuracy";
Serial.println(output);
}
// Function that is looped forever
void loop(void)
{
unsigned long time_trigger = millis();
if (iaqSensor.run()) { // If new data is available
output = String(time_trigger);
output += ", " + String(iaqSensor.iaq);
output += ", " + String(iaqSensor.iaqAccuracy);
Serial.println(output);
uint32_t free = system_get_free_heap_size();
Serial.print("Free RAM: ");
Serial.println(free);
} else {
checkIaqSensorStatus();
}
}
// Helper function definitions
void checkIaqSensorStatus(void)
{
if (iaqSensor.status != BSEC_OK) {
if (iaqSensor.status < BSEC_OK) {
Serial.println("Error");
for (;;) {}
} else {
Serial.println("Warning");
}
}
if (iaqSensor.bme680Status != BME680_OK) {
if (iaqSensor.bme680Status < BME680_OK) {
Serial.println("Error");
for (;;) {}
} else {
Serial.println("Warning");
}
}
}
This is the output of the ESP8266 Exception Decoder:
Exception 29: StoreProhibited: A store referenced a page mapped with an attribute that does not permit stores
