Neurosky mobile 2 with python 3 and bluetooth

[RahamaTahir]

I have four things to ask you.
1. What does the purpose of using missing bytes in this function from MindWavemobileRawReader.py file:
def _readBytesFromMindwaveMobile(self, amountOfBytes):
missingBytes = amountOfBytes
receivedBytes = ""
while(missingBytes > 0):
receivedBytes += self.mindwaveMobileSocket.recv(missingBytes)
missingBytes = amountOfBytes - len(receivedBytes)
return receivedBytes;
2. If i run this code i gor an error in the same above function that said:
Can't convert bytes into string
as recieced bytes are in string form
3. Is it possible to connect the headset without dongle?
4. And I'm using python 3 so the built in function that u use in many functions supposed to take string of length 1 but it recieved Bytes so it also give errors.

@robintibor : I wonder whether "MindWave Mobile 2" protocol is different or if it's supported too? (I don't own one)
If not, which linux-supported device would you suggest instead?
