[英]Pairing bluetooth devices with Passkey/Password in python - RFCOMM (Linux)
I am working on a Python script to search for bluetooth devices and connect them using RFCOMM .我正在研究 Python 脚本来搜索蓝牙设备并使用RFCOMM连接它们。 This devices has Passkey/Password.
此设备具有密钥/密码。 I am using PyBlueZ and, as far as I know, this library cannot handle Passkey/Password connections ( Python PyBluez connecting to passkey protected device ).
我正在使用 PyBlueZ,据我所知,该库无法处理密码/密码连接( Python PyBluez 连接到密码保护设备)。
I am able to discover the devices and retrieve their names and addresses:我能够发现设备并检索它们的名称和地址:
nearby_devices = bluetooth.discover_devices(duration=4,lookup_names=True,
flush_cache=True, lookup_class=False)
But if tried to connect to a specific device using:但是,如果尝试使用以下方式连接到特定设备:
s = bluetooth.BluetoothSocket(bluetooth.RFCOMM)
s.connect((addr,port))
I get an error 'Device or resource busy (16)'
.我收到错误
'Device or resource busy (16)'
。
I tried some bash commands using the hcitool and bluetooth-agent , but I need to do the connection programmatically.我使用hcitool和bluetooth-agent尝试了一些 bash 命令,但我需要以编程方式进行连接。 I was able to connect to my device using the steps described here: How to pair a bluetooth device from command line on Linux .
我能够使用此处描述的步骤连接到我的设备: How to pair a bluetooth device from command line on Linux 。
I want to ask if someone has connected to a bluetooth device with Passkey/Password using Python. I am thinking about to use the bash commands in Python using subprocess.call()
, but I am not sure if it is a good idea.我想问一下是否有人使用 Python 通过密码/密码连接到蓝牙设备。我正在考虑使用 subprocess.call
subprocess.call()
在 Python 中使用 bash 命令,但我不确定这是否是个好主意。
Thanks for any help.谢谢你的帮助。
Finally I am able to connect to a device using PyBlueZ. 最后,我能够使用PyBlueZ连接到设备。 I hope this answer will help others in the future.
我希望这个答案能在将来帮助其他人。 I tried the following:
我尝试了以下方法:
First, import the modules and discover the devices. 首先,导入模块并发现设备。
import bluetooth, subprocess
nearby_devices = bluetooth.discover_devices(duration=4,lookup_names=True,
flush_cache=True, lookup_class=False)
When you discover the device you want to connect, you need to know port, the address and passkey. 当您发现要连接的设备时,您需要知道端口,地址和密码。 With that information do the next:
有了这些信息,请做下一步:
name = name # Device name
addr = addr # Device Address
port = 1 # RFCOMM port
passkey = "1111" # passkey of the device you want to connect
# kill any "bluetooth-agent" process that is already running
subprocess.call("kill -9 `pidof bluetooth-agent`",shell=True)
# Start a new "bluetooth-agent" process where XXXX is the passkey
status = subprocess.call("bluetooth-agent " + passkey + " &",shell=True)
# Now, connect in the same way as always with PyBlueZ
try:
s = bluetooth.BluetoothSocket(bluetooth.RFCOMM)
s.connect((addr,port))
except bluetooth.btcommon.BluetoothError as err:
# Error handler
pass
Now, you are connected!! 现在,你已经连接!! You can use your socket for the task you need:
您可以使用套接字完成所需的任务:
s.recv(1024) # Buffer size
s.send("Hello World!")

Is there a way to connect two phones via Bluetooth, the script should be running on a Linux host.有没有办法通过蓝牙连接两部手机,脚本应该在 Linux 主机上运行。 Any suggestions of using pybluez or any other APIs?
使用 pybluez 或任何其他 API 的任何建议?
I have seen some examples where a Linux host is used as Client and is connect a phone (which is a server), but here I'm want to use Linux host as just a device to run the script and make two phones connect via Bluetooth.我已经看到一些示例,其中 Linux 主机用作客户端并连接手机(这是服务器),但在这里我想使用 Linux 主机作为运行脚本并使两部手机通过蓝牙连接的设备.
