Hi,

I am trying to use Python to connect to Nonin's 4100 OEM bluetooth pulse oximeter (to measure heart rate). The datasheet is here:
http://www.nonin.com/documents/4100%...ifications.pdf

Right now, I am trying to modify this program (below) to work with the sensor. When I connect however, the program just print reading... and then does nothing. For now, I would be happy if I could just get anything from the sensor, but I eventually want to be able to get the heart rate. According to Nonin, the heart rate can be found using:
HR = HRMSB * 128 + HRLSB. So... if I could get the HRMSB and HRLSB from the sensor, I would be quite happy

And here is the sorta not maybe half working code

import appuifw, socket, e32

target = ''
target = ('00:a0:96:17:d6:fc',1)   

def connectGPS():
    global sock, target
    # create a bluetooth socket and connect to GPS receiver:  (if it is a Nokia LD-3W the PIN is: 0000)
    #try:
    sock=socket.socket(socket.AF_BT,socket.SOCK_STREAM)
    if target == '':
        address,services = socket.bt_discover()
        print "Discovered: %s, %s"%(address, services)
        target = (address, services.values()[0])
    print "Connecting to " + str(target)
    sock.connect(target)
    appuifw.note(u"Pulse Oximeter successfully connected!", "info"
    print "connected!"
    readData()
    #except:
    #    if appuifw.query(u"Device problem. Connect again?","query") == True:
    #        sock.close()
    #        connectGPS()
    #    else:
    #        sock.close()

def readData():
    global sock
    packet_received = 0
    print "reading ..."
    while(0 == 0):
        ch = sock.recv(1)
	print str(ch)
        # Loop until packet received
        buffer = ""
        while(1==1):
            buffer+=ch
            ch = sock.recv(1)
	    print str(ch)
	print str(buffer)
        if (buffer[0:1]!=""):
            gpsData = buffer.split(",")
            lat = gpsData[2]
            lon = gpsData[4]
            if lat == '' :
                pass
            else:
                packet_received = 1
                appuifw.note(u'Sucessful GPS location reading! ' + unicode(lat) + u' ' + unicode(lon), "info")
                print "reading done!"
                print "Press Options key!"
                sock.close()
        else:
            pass


def exit_key_handler():
    script_lock.signal()
    sock.close()

script_lock = e32.Ao_lock()

print "Press Options key!"

appuifw.app.title = u"BT GPS reader"
appuifw.app.menu = [(u"get GPS location", connectGPS)]
appuifw.app.exit_key_handler = exit_key_handler
script_lock.wait()

Thank you!!!!!!!!!!!!!!!!!

PS: I'm using the Nokia N80 with Symbian 3rd edition
