BluetoothError'资源暂时不可用'

Question

每次我尝试运行代码的服务器功能时，无论我在什么代码上运行，我都会不断收到此错误。我已经在我的ubuntu笔记本电脑和树莓派上都尝试过。

Traceback (most recent call last):   File "/home/soham/.local/lib/python3.6/site-packages/bluetooth/bluez.py", line 167, in accept
    client, addr = self._sock.accept ()
_bluetooth.error: (11, 'Resource temporarily unavailable')

During handling of the above exception, another exception occurred:

Traceback (most recent call last):   File "Multi.py", line 89, in <module>
    server()   File "Multi.py", line 31, in server
    client_sock, client_info = sock.accept()   File "/home/soham/.local/lib/python3.6/site-packages/bluetooth/bluez.py", line 169, in accept
    raise BluetoothError (str (e)) bluetooth.btcommon.BluetoothError: (11, 'Resource temporarily unavailable')

有问题的代码段如下：

def server():
    sock.bind(("", port))
    sock.setblocking(False)
    sock.listen(1)

    name = "lights"

    print("Awaiting connection")

    BLE.advertise_service(sock, name)

    client_sock, client_info = sock.accept()
    print("Accepted connection from ", client_info)

    order = int(client_sock.recv(1024))
    print("order is ", order)

    message(order, client_sock)
