Thread and GPS positioning

[kenneth@hrensberg.dk]

Hi all

I have made the code below:

import e32
import thread
import positioning

def _lighton():
    while 1:
        print u"Thread called"
        e32.ao_sleep(2)

def lighton():
    thread.start_new_thread(_lighton, ())


positioning.set_requestors([{"type":"service","format":"application","data":"test_app"}])

def _gps_test():
    while 1:
        gps = (positioning.position(course=1,satellites=1, callback=None, interval=positioning.POSITION_INTERVAL, partial=0))
        pos_thread = gps["position"]
        
        print u"Pos: " + str(pos_thread["latitude"]) + ", " + str(pos_thread["longitude"])
        
        e32.ao_sleep(5)

def gps_test():
    thread.start_new_thread(_gps_test, ())

lighton()
_gps_test()

Which work fine, but I also want to have the GPS call in a thread, and for that I thought it would work if i changes the last line from "_gps_test()" to "gps_test()", but it doesn't... Why?!

I have made the code below

Looks like a mess. Forget about threads when reading gps with positioning.

import positioning
import appuifw
import e32

class GpsApp:
    def __init__(self):
        self.lock = e32.Ao_lock()
        self.pos = {} 
        appuifw.app.menu = [
            (u"GPS on",self.start_read_position),
            (u"GPS off",self.stop_read_position),
            (u"print pos",self.print_position),
            (u"Close", self.lock.signal),
        ]
        appuifw.app.exit_key_handler = self.exit_key_handler

    def start_read_position(self):
        positioning.set_requestors([{"type":"service", 
                                     "format":"application", 
                                     "data":"test_app"}])
        positioning.position(course=1,satellites=1,
           callback=self.read_position, # <-- !!!
           interval=1000000, partial=1  # <-- !!!
        ) 
        appuifw.note(u"Starting GPS...", 'info')

    def stop_read_position(self):
        appuifw.note(u"Stopping GPS...", 'info')
        positioning.stop_position()

    def read_position(self, pos):
        """Save the latest position object to the self.pos."""
        self.pos = pos

    def print_position(self):
        print "Current position:", self.pos

    def run(self):
        self.lock.wait()
        self.exit_key_handler()

    def exit_key_handler(self):
        if appuifw.query(u"Quit program", 'query') is True:
            self.running = False
            self.lock.signal()
        print u"Goodbye"


myApp = GpsApp()
myApp.run()
positioning.stop_position()

Oh-yeah... D'OH! Thank you...
