socket.recv problem

[docGroup14]

hi guys,

i am having a problem with socket.recv.

def readAndSend():
	global btSocket
	data_received = 0
	while(data_received == 0): #while there is not data, monitor channel
		channel = btSocket.recv(1)
		print u"got socket"
		buffer = ""
		while(channel != '\n'):
			buffer += channel
			channel = btSocket.recv(1)
			
		if(buffer[0:6] == "$GPGGA"):
			data = buffer.split(",")
			latitude = data[2]+data[3]
			longitude = data[4]+data[5]
			
			data_received = 1
		
			btSocket.close()

I am running this script every 30 seconds and it works the first time, however when it goes to run again it hangs at the first recv. This happens even if I close the socket then reconnect.

Is there anyway to get round this?

Thanks

just to let you know, this was solved by putting the connect and readData in one big method, instead of split up. Not sure why this solves it, but hey!!
