location.gsm_location() fails during (and a few seconds after) an internet connection or a telephone call in 3G/UMTS-network, if using Series60 3rd edition phone.

Test environment:

• PythonForS60_1_3_21_3rdEd_unsigned_freedevcert.SIS (signed with Ensymble and devcert with full caps)
• PythonScriptShell_1_3_21_3rdEd_unsigned_freedevcert.SIS (signed with Ensymble and devcert with full caps)
• Nokia E70 (firmware 2 and 3, tested both), fails in E65 too
• Elisa and Sonera 3G network in Helsinki, Finland
• A minimal test program:

import location, urllib, e32
print location.gsm_location()
urllib.urlretrieve("http://www.google.com", "D:/temp.html")
for i in range(20):
  loc=location.gsm_location()
  print "%d Loc: %s"%(i,loc)
  if loc is not None:
     print "got gsm-location"
     break
  e32.ao_sleep(1.0)

Usually 10th gsm_location() gives me expected result (mcc,mnc,lac,cell), first 9 results none.

NOTES:

• Your Python and script shell must be signed with at least Location capability
• Python must(?) be saved into phone's memory
• You have to be in 3G network (small 3G icon in phone's left top corner)
• Save code above as a file into C:/python/locbug.py
• Execute python and Run script "locbug.py"

This problem does not occur in 2nd edition phones or in GMS-cells.

If someone can confirm this bug, I'll send a bug report to sourceforge.

Hi aaaaapo,

I'm not sure that will help but try with

Try with

urllib.urlretrieve("http://www.google.com", "D:\\temp.html")

I don't have a signed version so I hope that someone else could help you.

I have noticed the same problem with N80 and E60 phones. Even though Python has been signed with devcert it sometimes gives None for location.

Hi aaaaapo,
i experienced the same problem during standard use of the gsm_location()-module on the N73. From time to time it just gives back "a none-array", which was causing my application to crash.

Okay, I'll file a bug (as soon as I find my sourceforge login/password :-).

Suggestion: make a wrapper function e.g. "get_location", which calls location.gsm_location() and handles possible none-array in some more clever way (e.g. returns tuple (0,0,0,0)).

The reason could be this:

(PyS60 uses the mentioned "CTelephony" internally)

If this is the case, we most probably have to wait for the firmware update.

Ok, I won't file a bug and try to live with this until new and shiny firmware is shipped. Thank you for information.

I can confirm it.

Mine is even worse: I always get "None".

Equipment: Nokia N80.
Python: 1.4.4 (3rdEd).
Network: phone shows "vodafone P" (Portugal).

hav you signed your script shell with location capabilities.
