我想使用蓝牙创建一个简单的客户端/服务器应用程序。我想使用 android 作为客户端,使用 Linux Mint 17 Cinnamon 64 位作为服务器。
我找到并改编了这个脚本:
import os
import glob
import time
from bluetooth import *
base_dir = '/home/dougui/devices/'
device_folder = glob.glob(base_dir)[0]
device_file = device_folder + '/w1_slave'
def read_temp_raw():
f = open(device_file, 'r')
lines = f.readlines()
f.close()
return lines
def read_temp():
lines = read_temp_raw()
while lines[0].strip()[-3:] != 'YES':
time.sleep(0.2)
lines = read_temp_raw()
equals_pos = lines[1].find('t=')
if equals_pos != -1:
temp_string = lines[1][equals_pos+2:]
temp_c = float(temp_string) / 1000.0
temp_f = temp_c * 9.0 / 5.0 + 32.0
return temp_c
server_sock=BluetoothSocket( RFCOMM )
server_sock.bind(("",PORT_ANY))
server_sock.listen(1)
port = server_sock.getsockname()[1]
uuid = "94f39d29-7d6d-437d-973b-fba39e49d4ee"
advertise_service( server_sock, "AquaPiServer",
service_id = uuid,
service_classes = [ uuid, SERIAL_PORT_CLASS ],
profiles = [ SERIAL_PORT_PROFILE ])
while True:
print ("Waiting for connection on RFCOMM channel %d" % port)
client_sock, client_info = server_sock.accept()
print("Accepted connection from ", client_info)
try:
data = client_sock.recv(1024)
if len(data) == 0: break
print("received [%s]" % data)
client_sock.send(data)
print("sending [%s]" % data)
except IOError:
pass
except KeyboardInterrupt:
print("disconnected")
client_sock.close()
server_sock.close()
print("all done")
break
现在,我想将我的 Android 设备连接到我的 PC。我跟着那些指示。
这是我发出的一些命令:

当我尝试点击手机中的电脑名称时,它会进行搜索并短暂标记“已连接到媒体音频”,但不到一分钟,连接就丢失了。连接成功时我收到此消息:
Nov 18 18:26:32 oscar kernel: [ 4968.066411] input: 50:A4:C8:3F:47:B2 as /devices/virtual/input/input26
我想在 Android 上使用 Blue term 应用程序。
我可以做什么来连接两个设备?
