Question

编程的新手。.我需要很少的帮助来实现如何在python中完成此特定任务..我需要在PC和andriod之间传输数据。.我尝试了套接字..它仅在活动的互联网连接上起作用（客户端/服务器方法）..我想尝试使用蓝牙或wifi，如果我尝试使用pybluez进行蓝牙.. andriod deos不支持它..并且它仅适用于linux，对于wifi我不知道如何开始/从哪里开始，欢迎提出任何建议

我使用Play商店（python 3.6>）中的python idle3在andriod上运行python脚本，在Windows上我具有python 3.6解释器

这只是解决wifi，这是我通常使用的一般结构。

服务器脚本：

import socket, os, time, sys, threading

HOST = '192.168.1.2' # The IP address of this server
PORT = 8888 # Arbitrary non-privileged port

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
print('Socket created')

#Bind socket to local host and port
try:
    s.bind((HOST, PORT))
except socket.error as msg:
    print('Bind failed. Error Code : ' + str(msg))
    sys.exit()

print('Socket bind complete')

#Start listening on socket
s.listen(10)
print('Socket now listening')

#Function for handling connections. This will be used to create threads
def clientthread(conn):
    try:
        #Sending message to connected client
        #print('Welcome to the server. Type something and hit enter')
        #conn.send('Welcome to the server. Type something and hit enter\n'.encode()) #send only takes string
        data = ""
        #infinite loop so that function do not terminate and thread do not end.
        toggle = True
        count = 0
        while True:
            data = ""
            #Receiving from client
            data = conn.recv(1024).decode().strip("\r")
            if data:
                print(data)
                conn.send((data + "\r").encode())
            time.sleep(.01)
    except Exception as e:
        exc_type, exc_obj, exc_tb = sys.exc_info()
        fname = os.path.split(exc_tb.tb_frame.f_code.co_filename)[1]
        print(exc_type, fname, exc_tb.tb_lineno)

    #came out of loop
    finally:
        conn.close()

#now keep talking with the client
while True:
    #wait to accept a connection - blocking call
    conn, addr = s.accept()
    print('Connected with ' + addr[0] + ':' + str(addr[1]))

    #start new thread takes 1st argument as a function name to be run, second is the tuple of arguments to the function.
    new_thread = threading.Thread(target = clientthread , args =(conn,))
    new_thread.daemon = True
    new_thread.start()

s.close()

客户端脚本：

import socket, time


TCP_IP = "192.168.1.2" # The IP address being connected to
TCP_PORT = 8888 # The socket being connected to

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
s.connect((self.TCP_IP, self.TCP_PORT))
time.sleep(.5)

while True:
  s.send("Testing".encode()) # Sends a message
  time.sleep(.5)
  data = s.recv(64) # Recieves up to 64 bytes, can be more
  print("recieved:", data)
  time.sleep(.5)

s.close()
