Overview

The PySymbian code posted here will basically do the following when run:

  • Immediately transmit LAC and CellID to predefined recipients via SMS (this allows for a rough containment of where you are located in your emergency)
  • Call an predefined emergency number
  • Try to get the GPS position of your phone and if it gets a signal transmit Latitude/Longitude and current speed every three minutes via SMS to predefined recipients

This sums up to a rather complete emergency package acting as some kind of panic button (place this as an .sis application on your today screen or similar...). If you ever get into an emergency immediately broadcast all relevant info to get help!

Code

import e32, appuifw, positioning, location, messaging, telephone
 
def gps_init():
global gps_data
gps_data = {
'satellites': {'horizontal_dop': 0.0, 'used_satellites': 0, 'vertical_dop': 0.0, 'time': 0.0,'satellites': 0, 'time_dop':0.0},
'position': {'latitude': 0.0, 'altitude': 0.0, 'vertical_accuracy': 0.0, 'longitude': 0.0, 'horizontal_accuracy': 0.0},
'course': {'speed': 0.0, 'heading': 0.0, 'heading_accuracy': 0.0, 'speed_accuracy': 0.0}
}
try:
positioning.select_module(positioning.default_module())
positioning.set_requestors([{"type":"service","format":"application","data":"gps_app"}])
positioning.position(course=1,satellites=1,callback=gps, interval=500000,partial=0)
e32.ao_sleep(3)
except:
appuifw.note(u'Problem with GPS','error')
 
def gps(event):
global gps_data
gps_data = event
 
def gps_stop():
#this function stops GPS
try:
positioning.stop_position()
except:
appuifw.note(u'Problem with GPS','error')
 
def gps_emerg():
gpessa = str( 'My GPS position is (Lat/Long/Geschwindigkeit): %s, %s, %i' % (pos_lat , pos_long, speed) )
print gpessa
messaging.sms_send('0123456789', gpessa) #PUT number of receipient you want to inform here
print 'GPS Position sent!'
print 'Recalling emergency phone number...'
telephone.dial('0123456789') #PUT some emergency number here
e32.ao_sleep(180)
 
ftrack = location.gsm_location()
messa = str( 'I have hit the panic button! My current cell information is LAC %s and Cell-ID %s. Trying to send my exact GPS position soon...' % (ftrack[2] , ftrack[3]) )
 
print messa
messaging.sms_send('0123456789', messa) #PUT number of receipient you want to inform here
print 'SMS sent!'
 
e32.ao_sleep(3)
 
print 'Calling emergency phone number...' #PUT some emergency number here
telephone.dial('0123456789')
 
gps_init()
count = 0
while True:
count = count + 1
sat = gps_data['satellites']['used_satellites']
pos_lat = gps_data['position']['latitude']
pos_long = gps_data['position']['longitude']
speed = gps_data['course']['speed']
if pos_lat > 0:
print 'Found GPS position, terminating call to free the line...'
telephone.hang_up()
e32.ao_sleep(1)
gps_emerg()
e32.ao_sleep(1)

PS: Credits also go to the original contributor of the GPS code. Please keep in mind that you will need the "unsigned_testrange" edition PySymbian for location/position capabilities to function properly.
