我正在尝试使用 Python 在我的 RaspberryPi 和 Bluegiga WT11i 蓝牙模块之间建立连接。
到目前为止，我来了：
pi@raspberrypi ~ $ hcitool scan
Scanning ...
00:07:80:54:CA:E2 BGWT11i
下一个 ...
pi@raspberrypi ~ $ python sdp-browse.py 00:07:80:54:CA:E2
found 1 services on 00:07:80:54:CA:E2
Service Name: Bluetooth Serial Port
Host: 00:07:80:54:CA:E2
Description: None
Provided By: None
Protocol: RFCOMM
channel/PSM: 1
svc classes: ['00001101-0000-1000-8000-00805F9B34FB']
profiles: []
service id: None
下一个 ...
pi@raspberrypi ~ $ python rfcomm-client.py 00:07:80:54:CA:E2
searching 00:07:80:54:CA:E2 for service
connecting to "Bluetooth Serial Port" on 00:07:80:54:CA:E2
Traceback (most recent call last):
File "rfcomm-client.py", line 28, in <module>
sock.connect((host, port))
File "<string>", line 5, in connect
bluetooth.btcommon.BluetoothError: (111, 'Connection refused')
这是代码（来自 PyBluez 示例）...
sdp-browse.py：
import sys
import bluetooth
if len(sys.argv) < 2:
print "usage: sdp-browser <addr>"
print " addr can be a bluetooth address, \"localhost\" or \"all\""
sys.exit(2)
target = sys.argv[1]
if target == "all" : target = None
services = bluetooth.find_service(address=target)
if len(services) > 0:
print "found %d services on %s" % (len(services), sys.argv[1])
print
else:
print "no services found"
for svc in services:
print "Service Name: %s" % svc["name"]
print " Host: %s" % svc["host"]
print " Description: %s" % svc["description"]
print " Provided By: %s" % svc["provider"]
print " Protocol: %s" % svc["protocol"]
print " channel/PSM: %s" % svc["port"]
print " svc classes: %s" % svc["service-classes"]
print " profiles: %s" % svc["profiles"]
print " service id: %s" % svc["service-id"]
rfcomm-client.py：
from bluetooth import *
import sys
addr = None
if len(sys.argv) < 2:
print "need address"
sys.exit(0)
else:
addr = sys.argv[1]
print "searching %s for service" % sys.argv[1]
uuid = "00001101-0000-1000-8000-00805f9b34fb"
service_matches = find_service( uuid = uuid, address = addr )
if len(service_matches) == 0:
print "couldn't find the service =("
sys.exit(0)
first_match = service_matches[0]
port = first_match["port"]
name = first_match["name"]
host = first_match["host"]
print "connecting to \"%s\" on %s" % (name, host)
sock=BluetoothSocket( RFCOMM )
sock.connect((host, port))
print "connected. type stuff"
while True:
data = raw_input()
if len(data) == 0: break;
sock.send("%s\n\r" % data)
sock.close()
我能做些什么？
