请教技术支持，关于Wido联网稳定性问题。
硬件为Wido+I/O扩展板+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。数据图http://www.yeelink.net/devices/79221
请问是硬件还是软件问题？如何解决？ 改延时，开始想改15秒，但好像编译过不去，最后设了10秒。 2~3小时候运行wido芯片是否发烫？过热可以考虑加散热片。15s应该是可以的，是不是哪里没一起改掉 Cain 发表于 2015-7-1 10:04
2~3小时候运行wido芯片是否发烫？过热可以考虑加散热片。15s应该是可以的，是不是哪里没一起改掉 ...
温度正常 :'(技术客服呢？！都一整天了，没个解决问题的意见？！ "15s应该是可以的，是不是哪里没一起改掉,"甚至说间隔可以再长点，，软件可以增加看门狗定时自动重启删除冗余。arduino本来就不像51有很强的稳定性 本帖最后由 szftrm 于 2015-7-2 09:14 编辑

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/ ，改个数字而已啊，怎么会报错？
要么使用内置看门狗http://www.geek-workshop.com/thread-2413-1-1.html，要不就用专用的芯片DS1232，比较推荐后一个 Cain 发表于 2015-7-2 10:47
