arduino yun 关闭wifi

happyfish2010

试着写了一段代码：

1. #include <Process.h>
   
2. int startPin = 7;
   
3. int stopPin = 6;
   
4. String strstart = "echo -n 'start' | socat - udp-connect:192.168.0.25:60002";
   
5. String strstop = "echo -n 'stop' | socat - udp-connect:192.168.0.25:60002";
   
6. void setup() {
   
7.   pinMode(startPin, INPUT);
   
8.   pinMode(stopPin, INPUT);
   
9.   Bridge.begin();
   
10. //  Serial.begin(9600);
    
11. }
    
12. 
    
13. void loop() {
    
14.   Process p;
    
15.   digitalWrite(startPin,HIGH);
    
16.   digitalWrite(stopPin,LOW);
    
17.   p.runShellCommand(strstart);
    
18.   delay(3000);
    
19.   digitalWrite(startPin,HIGH);
    
20.   digitalWrite(stopPin,LOW);
    
21.   p.runShellCommand(strstart);
    
22.   delay(3000);
    
23. }

然后把wifi关了，断电重启，刚开始可以控制继电器，能ping通，但1-2分钟后继电器停止工作，ping也ping不同....
