因Yeelink不稳定，我用使用WIDO连接Yeelink例程改为链接到OneNet平台，post语句测试，出现运行一段时间后自动停止传输数据，过一段时间后又恢复上传数据。 请问是什么问题？板子不稳定还是程序不稳定？求教高手  #include <Adafruit_CC3000.h> #include <ccspi.h> #include <SPI.h> #define Wido_IRQ 7 #define Wido_VBAT 5 #define Wido_CS 10 Adafruit_CC3000 Wido = Adafruit_CC3000(Wido_CS, Wido_IRQ, Wido_VBAT, SPI_CLOCK_DIVIDER); // you can change this clock speed // Security can be WLAN_SEC_UNSEC, WLAN_SEC_WEP, WLAN_SEC_WPA or WLAN_SEC_WPA2 #define WLAN_SECURITY WLAN_SEC_WPA2 #define WLAN_SSID "Tenda_42F538" // cannot be longer than 32 characters! #define WLAN_PASS "31323333" // For connecting router or AP, don't forget to set the SSID and password here!! #define TCP_TIMEOUT 3000 //#define CC3000_TINY_DRIVER #define WEBSITE "api.heclouds.com" #define API_key "Gb=2xmICfmN50mFFZ1vfxxiCVU=" // Update Your API Key.

1.稳定供电，不要用USB供电
2.增加看门狗定时自动重启删除冗余，保证效率最大化(ATMEGA32U4问题0 0)
ps：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。
3.yeelink现在好像要求上传间隔要大于等于10秒。看看是不是有这个问题
4.试着把发送间隔设长一点看看。
我估计应该是无线网络或者是板子的问题。再次感谢
