I am having issues connecting to two devices.  I can connect to either one 
individually, but not both at the same time.  I get the IOerror, unreachable 
network error.  I even tried threaded methods.  I am new to python, so it could 
be my code.

# Robot1 (NXT1)
host1="00:16:53:12:0c:42"
# Robot2 (NXT2)
host2="00:16:53:10:8e:94"
hosts=[host1,host2]

# Can't do both connection at same time, can do either of following
#b1 = nxt.bluesock.BlueSock(host1).connect()
#b1.message_write(0, 'ONE test' )
#b2 = nxt.bluesock.BlueSock(host2).connect()
#b2.message_write(0, 'TWO test' )

class ThreadClass(threading.Thread):
  def run(self):
    now = datetime.datetime.now()
    print "%s says Hello World at time: %s %s " % (self.getName(), now,hosts[0])
    print "%s says Hello World Host: %s" % (self.getName(),hosts[i])
    port=1
    ser1=BluetoothSocket( RFCOMM )
    ser1.connect((hosts[i], port))  
    ser1.settimeout(0)
    print "Thread %d connected to %s" % (i,hosts[i])
    #Alternate connection method using nxt-python
    #b = nxt.bluesock.BlueSock(hosts[i]).connect()
    #b.message_write(0, 'ONE test' )

for i in range(2):
  print "Starting thread %d to connect host %s" % (i,hosts[i])
  t = ThreadClass()
  t.start()
  time.sleep(1)

time.sleep(2)
print('Done with test!')

Any update on the original issue that was posted on Sep 21, 2011?

I seem to be running into the same issue on win7, running Python 2.6, and 
latest PyBluez

import bluetooth
BTSocket = bluetooth.BluetoothSocket(bluetooth.RFCOMM)
BTSocket.connect((target,12))

, where "target" is the bluetooth device address for my droid razr smartphone.

In addition to port 12, I tried with all available ports on my android phone 
device as shown by bluetooth.find_service(address = addr)

Can anyone help to resolve this?

Error message:

File "C:\Python26\lib\site-packages\bluetooth\msbt.py", line 53, in connect
    bt.connect (self._sockfd, addr, port)
IOError: A socket operation was attempted to an unreachable network.
