手机APP数据显示延迟问题解决
本帖最后由 海底沙 于 2017-9-30 08:49 编辑在做一个空调项目时,发现在手机端较快更改某个数据点数据时,数据显示有反复,
如温度从28度调到22度,APP显示从28----22----27----26----22,
效果见附件(不知如何上传视频,我以附件上传,下载后去掉".pdf"可看)
于是在gizwits_product.c中增加了一句,解决了这问题:

switch(info->event)

case EVENT_temp:
currentDataPoint.valuetemp= dataPointPtr->valuetemp;
GIZWITS_LOG("Evt:EVENT_temp %d\n",currentDataPoint.valuetemp);
//user handle
//目的是使下传的数据不再回传到云端,产生的后果是可能因网络原因造成设备端状态与APP端不一致
gizMemcpy((uint8_t *)&gizwitsProtocol.gizLastDataPoint, (uint8_t *)¤tDataPoint, sizeof(currentDataPoint));
break;
......
}
}
......
system_os_post(USER_TASK_PRIO_2, SIG_UPGRADE_DATA, 0);
return 0;
}
