Help. My app consumes to much energy

[szallah]

Hi.

I'm very new to programming in python.
Therefore, the code i have written consumes too much energy, and i don't really know where the problem could be.

I'd be very thankful for help.

import appuifw
import e32
import telephone
try:
    import miso
    misoon = True
except:
    misoon = False
try:
    import envy
    envyon = True
except:
    envyon = False

# unprotected UID
SYMBIAN_UID = 0xFFFFFFFF
SIS_VERSION = "0.5.1"
TITLE=u'abcd'
VERSION=TITLE + ' ' + SIS_VERSION

STATES = {telephone.EStatusUnknown:          "unknown",
          telephone.EStatusIdle:             "idle",
          telephone.EStatusDialling:         "dialing",
          telephone.EStatusRinging:          "ringing",
          telephone.EStatusAnswering:        "answering",
          telephone.EStatusConnecting:       "connecting",
          telephone.EStatusConnected:        "connected",
          telephone.EStatusReconnectPending: "reconnect pending",
          telephone.EStatusDisconnecting:    "disconnecting",
          telephone.EStatusHold:             "hold",
          telephone.EStatusTransferring:     "transferring",
          telephone.EStatusTransferAlerting: "transfer alerting"};



def handleCall((callState, number)):
    print "callState = "+STATES[callState]

    if callState == telephone.EStatusRinging:
      if number == "":
        print "incoming call"
      else:
        print "call from "+number
    elif callState == telephone.EStatusDialling:
      miso.vibrate(40000,1)
    elif callState == telephone.EStatusConnected:
      miso.vibrate(40000,0)
    elif callState == telephone.EStatusDisconnecting:
      miso.vibrate(40000,0)
      print "hung up"

def quit():
    global running
    running=0
    appuifw.app.set_exit()

def show_help():
    appuifw.note(u"I said the RED KEY!","info", 1)

def test_vibrate():
    miso.vibrate(1000,1)

def shout():
    index = lb.current()
    if index == 0:
        show_help()
    elif index == 1:
        test_vibrate()
    elif index == 2:
        quit()

if envyon == True:
    envy.set_app_system(1)
else:
    appuifw.note(u"Envy is missing!",'error')
if misoon == False:
    appuifw.note(u"Miso is missing!",'error')

print "waiting for a call"

entries = [u"Hide with RED KEY",u"Test vibration",u"Quit"]
lb = appuifw.Listbox(entries,shout)

app_lock=e32.Ao_lock()

appuifw.app.body = lb

running = 1

old_title = appuifw.app.title
appuifw.app.title = TITLE

appuifw.app.menu = [(u"Hide with RED KEY", show_help),(u"Test vibration", test_vibrate),(u"Quit", quit)]

appuifw.app.exit_key_handler = quit

while running:
    global STATES
    telephone.incoming_call()
    telephone.call_state(handleCall)
    e32.ao_yield()

appuifw.app.title = old_title

I know, my code is a mess. proboably very "noobish". But since the code is working, I need a solution for my energy-problem.

Kind regards...

Hello szallah and welcome to the Python Discussion Board.

The high energy consumption is most likely due to the "while running" loop. Since you used "telephone.incoming_call()" and "telephone.call_state(handleCall)" to wait for a call, the way I see it there is no need for the loop. See also this discussion.

Hope that helps

thanks bogdan... the difference between with "while running" and without is around 0,5W (that's what the energy profiler said)...
seems to work perfect now...

Hi,

I would guess miso.vibrate() uses also quite a lot of energy?

Cheers,

@JOM

of course it does. but vibrating is the purpose of my application, so there's really no other way. and, as far as i know, miso iss the only way to generate vibration.
and by removing the while-running-loop everything is working fine now.
