为什么我在 Tizen Native Wearable 中获得恒定步数？

Question

我是运行使用 Native 的 Tizen Wearable 步数监听器。我能够访问传感器数据，但它似乎永远打印相同的数据？我在这里做错了什么吗？使用 API 3 和 Samsung Galaxy Watch 3。

#include "stepcount.h"
#include "sensor.h"

void
example_sensor_callback(sensor_h sensor, sensor_event_s *event, void *user_data)
{
    /*
       If a callback is used to listen for different sensor types,
       it can check the sensor type
    */
    sensor_type_e type;
    sensor_get_type(sensor, &type);
    int i = 0;

    if (type == SENSOR_ACCELEROMETER) {
        unsigned long long timestamp = event->timestamp;
        int accuracy = event->accuracy;
        float x = event->values[0];
        float y = event->values[1];
        float z = event->values[2];
        dlog_print(DLOG_INFO, LOG_TAG, "ACCEL: %f %f %f", x,y,z);
    } else if (type == SENSOR_HRM) {
        unsigned long long timestamp = event->timestamp;
        int v = (int)event->values[0];
        dlog_print(DLOG_INFO, LOG_TAG, "Heart Rate: %.0f bpm", event->values[0]);
    }
    else if (type == SENSOR_HUMAN_PEDOMETER ){
            unsigned long long timestamp = event->timestamp;
            int accuracy = event->accuracy;
            int s = (int)event->values[0];
            int b = (int)event->values[1];
            dlog_print(DLOG_INFO, LOG_TAG, "Step Count: %d", event->values[0]);
            dlog_print(DLOG_INFO, LOG_TAG, "Walking Step Count: %d", event->values[1]);

    }
}

Base GUI
------
    bool supported = false;

    sensor_is_supported(SENSOR_HUMAN_PEDOMETER, &supported);
    if (!supported) {
        /* Accelerometer is not supported on the current device */
    }

    sensor_h sensor;
    sensor_get_default_sensor(SENSOR_HUMAN_PEDOMETER, &sensor);

    sensor_listener_h listener;
    sensor_create_listener(sensor, &listener);

    sensor_listener_start(listener);

    /* Register callback */
    sensor_listener_set_event_cb(listener, 1000, example_sensor_callback, NULL);

    sensor_listener_set_attribute_int(listener, SENSOR_ATTRIBUTE_PAUSE_POLICY, SENSOR_PAUSE_NONE);

这是我的日志

我想正确阅读我的实际步数。

请更正如下。

        dlog_print(DLOG_INFO, LOG_TAG, "Step Count: %d", s);
        dlog_print(DLOG_INFO, LOG_TAG, "Walking Step Count: %d", b);

或

        dlog_print(DLOG_INFO, LOG_TAG, "Step Count: %f", event->values[0]);
        dlog_print(DLOG_INFO, LOG_TAG, "Walking Step Count: %f", event->values[1]);
