Socket problem

[defragger]

Hy there!

I'm working on a wireless file-transfer program over bluetooth.
Its rather hard to find any dokumentation about this topic, but i at least
made it to resolve bluetooth devices in range and establish a connection.
the problem i now have is that every time i try to transfer files (obex format)
the program crashes and displays socket.error number 13: permission denied.
after I googled this error about 3 hours, i gave up, i couldnt find anything.
then i tried to use the RFCOMM class to transfer normal streams, but again
i got an error. this time it was: socket.error 0: error.
googling again, the same result as above: none.
i have also searched this forum, but couldnt find anything that fits.



The code for obex file transfer(client):

def cl_sv_func(target): # target = ('adress', port)
# make socket
mySocket = socket(AF_BT, SOCK_STREAM)

# if there is a server given, play client
if isNumberType(target[1]):

mySocket.connect(target)
# IO stuff here
send_path = u"c:\\simple_send.txt"
receive_path = u"c:\\"

f=open(send_path, 'w')
f.write("hello")
f.close

bt_obex_send_file(target[0], target[1], send_path)
bt_obex_receive(mySocket, receive_path)
# close socket
mySocket.close

# ... else do the server part


The code for obex file transfer(server):

# mySocket was made bevore, see client
# get server channel
port = bt_rfcomm_get_available_server_channel(mySocket._sock)

# bind socket to port
mySocket.bind(("", port))

# advertise service
bt_advertise_service( u"bla", mySocket._sock, True, OBEX )

# set security level: authorised
set_security(mySocket._sock, AUTHOR)

# listen to socket
tell("starting listening on Port: " + str(port))
mySocket.listen(1)
tell("waiting for connection...")

# if there is a connection request: accept
myConnection, adress = mySocket.accept()
tell("connected to: " + adress + ", " + str(port))

# IO stuff here
send_path = u"c:\\simple_send.txt"
receive_path = u"c:\\"

f=open(send_path, 'w')
f.write("hello you")
f.close

bt_obex_receive(mySocket, receive_path)
bt_obex_send_file(adress, port, send_path)

# close socket
mySocket.close


the code is partly from this forum, partly i made it up by myself, but i already found it nearly similar at other
places, so should work...
but as soon as the client starts to send: socket error 13: permission denied

i already tryed to skip the connect() and accept() statements, to see what
happens, but error was the same...
then i tried to bind the socket at the client part and set the security to author there too. worked, but did not fix the problem.



The code for rfcomm stream transfer(client):

# nearly same code as up, only with rfcom stream "IO"
def cl_sv_func(target): # target = ('adress', port)
# make socket
mySocket = socket(AF_BT, SOCK_STREAM)

# if there is a server given, play client
if isNumberType(target[1]):

mySocket.connect(target)
tell("connected to: " + target[0] + ", " + str(target[1]))

blaa = "bla"
mySocket.send(blaa.replace('\n','\r\n'))
rec = mySocket.recv(7)
tell(rec)

# close socket
mySocket.close

The code for rfcomm stream transfer(server):


# get server channel
port = bt_rfcomm_get_available_server_channel(mySocket._sock)

# bind socket to port
mySocket.bind(("", port))

# advertise service
bt_advertise_service( u"bla", mySocket._sock, True, RFCOMM )

# set security level: authorised
set_security(mySocket._sock, AUTHOR)

# listen to socket
tell("starting listening on Port: " + str(port))
mySocket.listen(1)
tell("waiting for connection...")

# if there is a connection request: accept
myConnection, adress = mySocket.accept()
tell("connected to: " + adress + ", " + str(port))

# IO stuff here
blaa = "workerr"

rec = mySocket.recv(3)
mySocket.send(blaa.replace('\n','\r\n'))
tell(rec)

# close socket
mySocket.close

... the code is partly from this forum, partly from the nokia simple_bluetooth
example, so should work. but again, as soon as the client phone is trying to receive: socket error 0.


as said: connection works, but as soon i try to send/receive something:
*BOINK*

Here are the phones I'm using:

Nokia 3230, pythonForSer60 2nEdFP2 => plays the client part
Nokia Ngage, pythonForSer60 2nEdFP2 => plays server part



If anyone got a clue, why i cant transfer anything, please respond!
you guys are my last hope, i dont want to give up days of work...
