python script to send OSC to SuperCollider using Neuroskys mindwave and NeuroPy module

I'm trying to send multiple OSC messages to Supercollider using the variables (1-13) from neuroPy. It works fine with only one variable. How can I utilize more variables.

from NeuroPy import NeuroPy
import time
import OSC

port = 57120
sc = OSC.OSCClient()
sc.connect(('192.168.1.4', port)) #send locally to laptop
object1 = NeuroPy("/dev/rfcomm0")
zero = 0
variable1 = object1.attention
variable2 = object1.meditation
variable3 = object1.rawValue
variable4 = object1.delta
variable5 = object1.theta
variable6 = object1.lowAlpha
variable7 = object1.highAlpha
variable8 = object1.lowBeta
variable9 = object1.highBeta
variable10 = object1.lowGamma
variable11 = object1.midGamma
variable12 = object1.poorSignal
variable13 = object1.blinkStrength


time.sleep(5)

object1.start()

def sendOSC(name, val):
    msg = OSC.OSCMessage()
    msg.setAddress(name)
    msg.append(val)
    try:
        sc.send(msg)
    except:
        pass
    print msg #debug



while True:
    val = variable1
    if val!=zero:
        time.sleep(2)
        sendOSC("/att", val)

This works fine and I get the message in Supercollider as expected.

What can I do to add more variables and get more messages?

I figured it should be something with setCallBack.

You do not need to send multiple OSC messages, you can send one OSC message with all the values in. In fact, this will be a much better way to do it, because all the updated values will arrive synchronously, and less network traffic will be needed.

Your code currently does the equivalent of

msg = OSC.OSCMessage()
msg.setAddress("/att")
msg.append(object1.attention)
sc.send(msg)

which is fine for one value. For multiple values you could do the following which is almost the same:

msg = OSC.OSCMessage()
msg.setAddress("/neurovals")
msg.append(object1.attention)
msg.append(object1.meditation)
msg.append(object1.rawValue)
msg.append(object1.delta)
# ...
sc.send(msg)

It should be fine, you'll get an OSC message with multiple data in. You can also write the above as

msg = OSC.OSCMessage()
msg.setAddress("/neurovals")
msg.extend([object1.attention, object1.meditation, object1.rawValue, object1.delta])  # plus more vals...
sc.send(msg)

Look at the documentation for the OSCMessage class to see more examples of how you can construct your message.
