Wifi disconnect (wifi:m f null)

Hi,

I started with ESP-IDF, now in version: 4.4.2

And my program reads the DS18B20 and controls the I2C device. Everything works for about 3 hours. Then the program fails.

Start log, where everything is OK.

Here is completed log

Any idea what could be wrong? I've been looking all day, but I don't know what to grab.

Hello to everybody.

Do you know where I was wrong? It's stupid, but I made a driver for the SHT30 over I2C. And once every xy milliseconds I read the temperature.

Code: Select all

void sht30_measure(void) {
	i2c_cmd_handle_t cmd = i2c_cmd_link_create();;

	cmd = i2c_cmd_link_create();
	i2c_master_start(cmd);
	i2c_master_write_byte(cmd, (SHT30_I2C_ADDRESS << 1) | I2C_MASTER_WRITE, true);
	i2c_master_write_byte(cmd, 0x2C, true);	// Send measurement command(0x2C)
	i2c_master_write_byte(cmd, 0x06, true); // High repeatability measurement(0x06)
	i2c_master_stop(cmd);
	i2c_master_cmd_begin(I2C_NUM_0, cmd, 10 / portTICK_PERIOD_MS);
	i2c_cmd_link_delete(cmd);
}

And look at these two lines.

Code: Select all

	i2c_cmd_handle_t cmd = i2c_cmd_link_create();
	cmd = i2c_cmd_link_create();

If we look inside the function:

Code: Select all

i2c_cmd_handle_t i2c_cmd_link_create(void)
{
#if !CONFIG_SPIRAM_USE_MALLOC
    i2c_cmd_desc_t *cmd_desc = (i2c_cmd_desc_t *) calloc(1, sizeof(i2c_cmd_desc_t));
#else
    i2c_cmd_desc_t *cmd_desc = (i2c_cmd_desc_t *) heap_caps_calloc(1, sizeof(i2c_cmd_desc_t), MALLOC_CAP_INTERNAL | MALLOC_CAP_8BIT);
#endif
    return (i2c_cmd_handle_t) cmd_desc;
}

In my app is use: calloc. So I allocated memory twice, but freed it once.

So the error was in the SHT30 driver, not in the wifi.
