Python 在尝试连接到raspberry pi上的obexpushd服务时，PyOBEX失败

我正在尝试运行一个python脚本，它允许我将一个文件发送到位于raspberry pi上的obexpushd服务

代码本身非常简单

从蓝牙导入*
从PyOBEX.client导入客户端
导入系统
serverMACAddress='B8:27:EB:7C:30:45'
端口=9
client=client（serverMACAddress，端口）
client.connect（）
client.disconnect（）

在覆盆子圆周率方面，似乎所有的设置都是正确的

sudo obexpushd -B -o books/ -n &
sudo bluetoothctl
discoverable on
Changing discoverable on succeeded
[CHG] Controller B8:27:EB:7C:30:45 Discoverable: yes

但是，当我尝试运行python脚本时，会弹出一条消息，持续几秒钟

在退出之前，python会发出一条错误消息

2020-11-13 20:57:14.797 Python[1373:19719] instantiateOnDevice for regular

有人知道发生了什么吗？

看起来，当您配对这两台设备时，

obexpushd

没有在RPi上运行。如果在

bluetoothctl

中使用

agent on

和

default agent

命令，则应提示您接受连接。
