本文讨论了使用Wido+I/O扩展板+LM35线性模拟温度传感器上传数据到Yeelink时遇到的联网稳定性问题。最初,每隔一次温度数据上传会返回一个频繁请求错误提示。通过将程序中的延时从2秒改为10秒,解决了该问题。然而,数据上传约2-3小时后仍然会出现无数据且传感器异常的情况,需要重启Wido才能恢复正常。文章提供了具体的故障排查方法和解决方案,帮助用户解决这一问题。

硬件为Wido+I/O扩展板+[size=12.727272033691406px]LM35线性模拟温度传感器; 程序为样例Wido2Yeelink 刚开始串口窗中,每隔一次温度数据上传会返回一个错误提示,如下: 3c {"error":"TOO FREQUENTLYREQUESTS (INTERVAL MORE THAN 10S)"} 因此将程序中延时2S改为延时10秒(好像改15S有问题),如下: if(WidoClient.connected() &&millis() - uploadtStamp > 10000){ 再调试则无此报错。 但一直出现数据上传约2-3小时后在yeelink端无数据并且显示传感器异常,需要重启Wido才能恢复正常,但问题反复未解决。 请问是硬件还是软件问题?如何解决? |





,改个数字而已啊,怎么会报错?
This example code is used to connect the Yeelink cloud service (Official homepage: www.yeelink.net).
The device required is just:
1. LM35 low cost temperature sensor or any device you used to upload data
2. And Wido
Note: Please don't forget to change the setting below before using!
1. WLAN_SSID & WlAN_PASS
2. API_key
3. device ID & sensor ID

都没怎么改动过。另看门狗加那里/
