Able to get accelerometer data without running mpu6050_init

[Ishan-Sharma-17]

I am using this library to code my mpu6500 using an esp32-s3 board. I was running the following commands to activate and then get data from my MPU:

esp_err_t ret;
    i2c_config_t conf = {
        .mode = I2C_MODE_MASTER,
        .sda_io_num = I2C_MASTER_SDA_IO,
        .sda_pullup_en = GPIO_PULLUP_ENABLE,
        .scl_io_num = I2C_MASTER_SCL_IO,
        .scl_pullup_en = GPIO_PULLUP_ENABLE,
        .master.clk_speed = I2C_MASTER_FREQ_HZ,
    };
    float accel_bias[3] = {0.00f, 0.00f, 0.00f};
    float gyro_bias[3] = {0.00f, 0.00f, 0.00f};

    ret = i2c_param_config(I2C_MASTER_NUM, &conf);
    if (ret != ESP_OK) {
        printf("I2C param config failed\n");
        return -1;
    }
    ret = i2c_driver_install(I2C_MASTER_NUM, conf.mode, 0, 0, ESP_INTR_FLAG_DEFAULT);
    if (ret != ESP_OK) {
        printf("I2C driver install failed");
        return -2;
    }

    ret = mpu6050_init(I2C_MASTER_NUM);
    if (ret != ESP_OK) {
        printf("MPU Initialization failed\n");
        return -3;
    }

    mpu6050_calibrate(I2C_MASTER_NUM, accel_bias, gyro_bias);
    ESP_LOGI("MPU6050", "Calibration complete");

However, when I run this code, my code prints "MPU Initialization failed", which means the line ret = mpu6050_init(I2C_MASTER_NUM); throws an error. However, I can still get the data later on in my program from some other code. So, I decided to see if commenting out the ret = mpu6050_init(I2C_MASTER_NUM); line does anything, and when I tried that, I am still able to get the data.

Could anyone help me understand why the initialization line does not seem to be necessary to program my mpu6500?
