gsm location in python
I have this script file in python ru开发者_Go百科nning on S60:
import location
def current_location():
gsm_loc = location.gsm_location()
print gsm_loc
current_location()
instead of printing a tuple of mcc, mnc, lac and cellId it prints None.
on top of my python shell I see location between the capabilities included.
what can be the problem?
Development of the situation:
I thought maybe nevertheless, my problem is lack of capabilities. So I went to sign the PythonScriptShell file. I used OPDA website - I know they sign all the capabilities but three - which I don't use. I installed the signed PythonScriptShell file on my phone (N95). On the top the list of capabilities didn't change. tried to run the script again: same result - prints None.
If anyone can help me with this, it's really important.
thank you.
I think I can answer now one part of the problem:
the reason for printing None is because there needed another capability: ReadDeviceData which wasn't included in the capabilities list on top of python shell.
still, remaining the other part of the problem, why this capability wasn't included when I signed PythonScriptShell file? It is not one of the three restricted capabilities.
I have same issue with all necessary scriptshell capabilities: 'PowerMgmnt', 'ReadDeviceData', 'WriteDeviceData', 'TrustedUI', 'ProtServ', 'SwEvent', 'Network services', 'LocalServices', 'ReadUserData', 'WriteUserData', 'Location', 'SurroundingsDD', 'UserEnviroment'.
Let's take a look at source code from PythonForS60/module-repo/dev-modules/location.py
:
import e32
import _location
def gsm_location():
if e32.s60_version_info>=(3,0):
ret = _location.gsm_location()
if ret[4]==1: # relevant information ?
return (int(ret[0]),int(ret[1]),ret[2],ret[3])
else:
return None # information returned by _location.gsm_location() not relevant
else:
return _location.gsm_location()
On my Nokia E71 e32.s60_version_info == (3,1)
and I get None
value too.
I don't really know what means 'not relevant', but direct calling
>>> import _location
>>> _location.gsm_location()
(u'257', u'01', 555, 11, 0)
returns something close to my objective reality.
