我試圖從我的Arduino通過LAN連接上我的筆記本電腦運行Windows 10創建一個Python服務器從Arduino的CC3000客戶
的端口65將數據發送到我的電腦現在收到的數據，我沒有由於我的主要障礙，達到了數據部分：我無法讓CC3000連接到我的Python服務器。
從Arduino的調試只是如果它無法連接你所期望的，但在這裏你去：（顯然經過一段時間它在發現我的電腦的IP地址放棄）

這裏是我的Arduino的代碼（我有一個Linksprite CC3000，但我使用的Adafruit的CC3000庫）：
#include <Adafruit_CC3000.h>
#include <ccspi.h>
#include <SPI.h>
#include <string.h>
#include "utility/debug.h"
#include <stdlib.h>
// These are the interrupt and control pins
#define ADAFRUIT_CC3000_IRQ 3 // MUST be an interrupt pin!
#define ADAFRUIT_CC3000_VBAT 5 // Apparently these can be any two pins
#define ADAFRUIT_CC3000_CS 10 // But I wouldn't change these...
// Use hardware SPI for the remaining pins (On a Mega 2560, SCK = 52, MISO = 50, and MOSI = 51)
Adafruit_CC3000 cc3000 = Adafruit_CC3000(ADAFRUIT_CC3000_CS, ADAFRUIT_CC3000_IRQ, ADAFRUIT_CC3000_VBAT, SPI_CLOCK_DIV2);
#define WLAN_SSID "ARK_TP-LINK_2.4GHz_FFBC77"
#define WLAN_PASS "AHomeRWirelessK1!"
#define WLAN_SECURITY WLAN_SEC_WPA2
String readString = String(100); //string for fetching data from address
uint32_t ip = (192 << 24) & (168 << 16) & (0 << 8) & (115); // This translates into the ip address we need
// 323223552X; 192.168.0.X
void setup() {
// put your setup code here, to run once:
Serial.begin(115200);
Serial.print(F("Initializing CC3000............."));
if (!cc3000.begin())

int DHCPTimeout = 0;
bool failed = false;
Serial.print(F("Requesting DHCP..."));
Serial.println("\n" + (!cc3000.checkDHCP()));
while (!cc3000.checkDHCP() && DHCPTimeout < 16)
{ //Obtain IP addeess
Serial.println("Failed!");
delay(1000);

cc3000.printIPdotsRev(ip);
Adafruit_CC3000_Client client = cc3000.connectTCP(ip, 65);

char c = client.read();
Serial.print(c);

當然，Python代碼是非常簡單的比較：
import socket
import time
import smtplib as smtp
def send_email(subject, message, to): #Send an email
fro = "[email protected]"
print("Sending Email:",subject)
server = smtp.SMTP("smtp.gmail.com", 587)
server.ehlo()
server.starttls()
server.ehlo()
server.login(fro, "alphabetagammadelta")
header = "To:" + to + "\n" + "From: " + fro + "\n" + "Subject:" + subject + "\n"
#header for message contains to, from, and subject
msg = header + "\n" + message + " \n\n"
#formulate packet using header and message
server.sendmail(fro, to, msg)
server.close()
def createServer(): #Create a server to recieve
global sock #data from the Arduino
sock = socket.socket()
host = socket.gethostname()
print("Initializing Server")
print("Host:", host)
port = 65
print("Port:", port)
sock.bind((host, port))
#print(sock.bind((host, port)))
sock.listen(5)
while 1:
c, addr = sock.accept()
c.send("Connected!")
print("Connected to "+addr[0]+":"+str(addr[1]))
print(c.recv(1024))
createServer()
名稱解析Python代碼和Arduino的之間的溝通出錯並返回'0.0.0.0'。對於第一次測試，嘗試對IP地址進行硬編碼。 –
我原來的IP硬編碼，它仍然無法正常工作，所以我覺得我的動態IP地址有點奇怪。 –
但謝謝你的幫助。 –
