ESP_LOGE let the esp32 restat,when i use this fun(),want to know the reason?

[liankafohali]

Code: Untitled.c Select all

void send_deviceData(){

    //static const char *buff="test";

    char buff[100]={"0"};

    sprintf(buff,"{'DeviceId':%s,'DeviceName':%s,'Mode':%d,'Power':%d,"

    "'ProNum':%s}",deviceData.DeviceId,deviceData.DeviceName,

    deviceData.Mode,deviceData.Power,deviceData.ProNum);



    while(1){

        int err = send(sock, buff, strlen(buff), 0);

        if (err < 0) {

            ESP_LOGE(TAG, "Error occurred during sending: errno %d", errno);

        }

        /*

        else{

            //ESP_LOGE(TAG, "Send bytes success,content");

        }

        */

    vTaskDelay(2000/portTICK_RATE_MS);

    }

    vTaskDelete(send_devdahandle);



}

when i use xTaskCreate(send_deviceData, "send_deviceData", 1024, NULL,3, send_devdahandle) to create a new task,above is the task fun(),but when i remove this part of the code

Code: Untitled.c Select all

        

else{

//ESP_LOGE(TAG, "Send bytes success,content");

 }

the problem disappeared.

Attachment is serial port printing information.

Its because task stack size is only 1024 bytes. If you are using any functions to print logs in task then it should be over 3 or 3.5kB (dont remember accurate value). Save is to set it to 4kB, as you may use task stack for other variables too.
