我想在Raspbian Linux上运行一个非常简单的蓝牙服务器。如果它有什么区别,我正在使用Raspberry Pi 3的蓝牙适配器,而不是加密狗。Linux上的Pybluez RFCOMM服务器没有可推广的服务

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) 
except IOError: 
    pass 

print("disconnected") 

client_sock.close() 
server_sock.close() 
print("all done") 

运行时产生以下错误:

Traceback (most recent call last): 
    File "rfcomm-server.py", line 15, in <module> 
    profiles = [ SERIAL_PORT_PROFILE ], 
    File "build/bdist.linux-armv7l/egg/bluetooth/bluez.py", line 268, in advertise_service 
bluetooth.btcommon.BluetoothError: error no advertisable device. 

我见过很多人用这个确切的代码,所以我有点惊讶我还没有发现这个任何提及具体问题。此外,这个客户端版本工作得很好。

启用“启用页和查询扫描”,由下面的命令:

$ hciconfig hciX piscan

谢谢,我应该提到去年我想通了这一点。原来我没有串口配置文件,需要在兼容模式下运行守护进程。对于其他任何人来说,答案可以在这里找到https://www.raspberrypi.org/forums/viewtopic.php?f=63&t=133263 – user3781314
