did i break my phone?

[docGroup14]

hi guys, been messing about as you can probably tell from my previous posts but now i think i may have broken something!

my phone will no longer connect bluetooth from the python interpreter. it will accept bluetooth connections from the computer and from the gps unit, however when i run code that used to work it no longer connects or brings up the discover box.

i have done a hard reset and reinstalled python interpreter but it still doesn't work.

is there anything else i can do?

thanks

Hello docGroup14

Well would you like to share your code that you use to connect your device through bluetooth? I think that may provide some help to ypu as well.Moreover if your Bluetooth connections are working fine outside python interpreter as you have mentioned., then i dont think that there might be some fault with your device..Just a minor code error..So do paste your code here...

Hope that helps

hi, thanks for the reply. i did manage to run bt_discover from some other code so you are right it is indeed a code error.

here is the code, it crashes, i think because of multiple threads. Y.A.K was helping me in my other thread.

def gps():
        #checks gps

def gpsDaemon():
	gps()
	gpsTimer.after(30, gpsDaemon)

def handle_selection():
	index = lb.current()
	code = choices[index][1]

	if code == "startGPS":
		thread.start_new_thread(gpsDaemon,())
       
	elif code == "stopGPS":
		gpsTimer.cancel()

thanks

edit: i have also tried it with thread locks as Y.A.K suggested but that crashed too, i have also tried it so that gpsDaemon starts a new thread gps(), but this crashed too!!

	btSocket = socket.socket(socket.AF_BT, socket.SOCK_STREAM) #create bluetooth socket
		if mac_address == '':
			address,services = socket.bt_discover() #search bluetooth devices
			print "Discovered: %s, %s"%(address, services)
			mac_address = (address, services.values()[0])
			if appuifw.query(u"Do you want to always connect to this device?", "query") == True:
				f = open("c:\\mac_address", 'wb')
				marshal.dump(mac_address, f)
				f.close()
		btSocket.connect(mac_address)

this is the code that doesn't appear to work. even though it used to however if i just make a new file with socket.socket(socket.AF_BT, socket.SOCK_STREAM) then do bt_discover then it works.

oh crap, sorry for wasting your time was a really dumb error on my part.

[y.a.k]

Please do share it with us to help others that get themselfes in a simmilar situation.

The code from your previous post (the one that crashes for you) isn't right. You're sharing a timer between threads there. You should only start gps function in a separate thread.

def gps():
        #checks gps
        pass

def gpsDaemon():
        thread.start_new_thread(gps, ())
	gpsTimer.after(30, gpsDaemon)

def handle_selection():
	index = lb.current()
	code = choices[index][1]

	if code == "startGPS":
                gpsTimer.after(0, gpsDaemon)
       
	elif code == "stopGPS":
		gpsTimer.cancel()

This really shouln't crash as long as you don't do anything illegal in the gps() function. Illegal would be accessing main thread's active objects or appuifw module. I'm not sure about limitations of gps things thou.

thanks Y.A.K i will give it a shot. my dumb error was that im testing for mac_address == ''

but i tried to load something into mac_address, and if there was an exception i just wrote "pass". when i changed this to mac_address = '' then it worked fine!!!

the only reason it hadn't failed before was because i was always loading something into mac_address - when i deleted the file being loaded the error popped up!

ah the reason i didn't want to use something like this is because if the gps thread takes longer than 30 seconds to complete, then another thread will still be made. when you told me to use thread.allocate_lock() i thought that you were onto something, but that still crashed so i have no way of knowing when the gps thread finishes and therefore when i should start scheduling a new one.

unless i can use the locks in the gpsDaemon function.

by the way, when i say crash i mean the program still ran but was unresponsive - it didn't crash out of the interpreter. it kept hanging / crashing when i made a new thread.

thanks

You can use a global flag that will tell you if the thread is still running.

yeah im going to use that, but i dont like it

edit: the reason i dont like it, is that it requires a busy wait or a timer waiting until the gps has finished.
