SL4A客户端Python服务器(SL4A client Python server)

概要

我想在Android Phone作为客户端和Python作为服务器之间建立蓝牙连接。 请帮帮我，我无法弄清楚。 服务器端必须在PC上使用Python。 我需要Python代码作为服务器，而Sl4A可以连接到这台PC。 我尝试了很多代码，但没有让它工作。

SL4A Bluetooth_chat.py

import android

import time

droid = android.Android()

droid.toggleBluetoothState(True)

droid.dialogCreateAlert('Be a server?')

droid.dialogSetPositiveButtonText('Yes')

droid.dialogSetNegativeButtonText('No')

droid.dialogShow()

result = droid.dialogGetResponse()

is_server = result.result['which'] == 'positive'

if is_server:

droid.bluetoothMakeDiscoverable()

droid.bluetoothAccept()

else:

droid.bluetoothConnect()

if is_server:

result = droid.dialogGetInput('Chat', 'Enter a message').result

if result is None:

droid.exit()

droid.bluetoothWrite(result + '\n')

while True:

result = droid.dialogGetInput('Chat', 'Enter a message').result

if result is None:

break

droid.bluetoothWrite(result + '\n')

droid.exit()

我的答案

import requests

from bluetooth import *

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, "SampleServer",

service_id = uuid,

service_classes = [ uuid, SERIAL_PORT_CLASS ],

profiles = [ SERIAL_PORT_PROFILE ],

# protocols = [ OBEX_UUID ]

)

print("Waiting for connection on RFCOMM channel %d" % port)

client_sock, client_info = server_sock.accept()

print("Accepted connection from ", client_info)

try:

while True:

data = client_sock.recv(1024)

if len(data) == 0: break

print("received [%s]" % data)

params=userdata)

except IOError:

pass

print("disconnected")

client_sock.close()

server_sock.close()

print("all done")

Summary

I want a Bluetooth connection between an Android Phone as client and Python as server. Please help me I can't figure it out. Server side must be on PC with Python. I need Python code as server and Sl4A can connect to this PC. I tried a lot of code but didn't get it to work.

尝试使用Google发布的SL4A和ACTS：

SL4A位置： aosp_root/external/sl4a

ACTS测试框架位置： aosp_root/tools/test/connectivity

在测试框架内有一个测试用例，可以帮助您了解BT

通过SPP进行测试： aosp_root/tools/test/connectivity/tests/google/bt/SppTest.py

Try using SL4A and ACTS that Google released:

SL4A location: aosp_root/external/sl4a

ACTS Test Framework Location: aosp_root/tools/test/connectivity

Within the test framework there is a testcase that can give you a start on BT

用SD卡啊。 复制到卡上，然后用文件管理器打开就可以了。 我以前在android, symbian上都安装过python。不过android上的python只是偶尔用过几次。

好的，所以我很难找到一个droid命令来写文件。 标准的Python open，write，read，close命令工作正常。 Ok, so I was silly to look for a droid command to write files. The standard Python open, write, read, close commands work fine.

我想你要把你的脚本嵌入一个apk上才行，看看维基吧： http://code.google.com/p/android-scripting/wiki/SharingScripts#Scripts_as_APKs

我决定写我自己的(见下面供参考)。 这可能会变得更好，欢迎任何建议。 import android, os, time

droid = android.Android()

# Specify root directory and make sure it exists.

base_dir = '/sdcard/sl4a/scripts/'

if not os.path.exists(base_dir): os.makedirs(base_dir)

由于Android内核中缺少驱动程序， pyserial无法正常工作。 然而， sl4a内置USB主机串行支持，具有良好的兼容性 ( 此处为示例代码 )。 pyserial is not working due to missing drivers in the Android kernel. However sl4a has builtin USB Host Serial support with good compatibility (example code here).
