lightblue for python 1.9.x

[finnsmama]

Hey all,
I downloaded a zip file containing source code for the lightblue module that claims to be compatible with pyx60 1.9.x. The file I downloaded (lightblue-0.4_s60-3rdEd-FP2_freedevcert_PyS60-1.9.x.zip) can be found herehttp://sourceforge.net/projects/lightblue/files/

However, no .sis file is available. I noticed in the source for previous (non 1.9.x compatible) versions of lightblue that there is the _lightblueutil module (in the source for these versions it is c++ code.) The source code that I downloaded above does NOT have the _lightblueutil source, it *does* include a file called "kf__lightblueutil.pyd". As you can tell I am a newbie, I am trying to get a python script code written in pys60 1.9.6 to use the lightblue module, but the python shell script says it can't find the module _lightblueutil. I put the following files in the E:/Python/Lib/ directory on my phone's (N79) memory card.:

• _lightblue.py
• _lightbluecommon.py
• _obex.py
• _obexcommon.py
• kf__lightblueutil.pyd
• obex.py
• __init__.py

Any ideas? What am I doing wrong? How, in general, are .pyd files used/installed? How would I make a .sis file for this version of lightblue?

i don't know if anyone else feels the same way, but for those who develop python apps on the mobile device whilst commuting, the new way of distributing extensions is a tedious task if the sis isnt supplied.

you need to use ensymble "simplesis" command to create the sis file which will chuck the
.pyd file in e:\sys\bin\
and .py wrapper to c:\data\python25

I've not worked out how to do this for separate drives, so have been compiling from source codes with Carbide.

Hi finnsmama,

A few weeks ago I was struggling with lightblue quite a lot (actually the developer recompiled the module for 1.9.x on my request...).

The only solution, that worked for me in the end to use the module was to extract the zip file to module-repo folder (C:\Program Files\PythonForS60\module-repo\dev-modules in my case) and in the script that you want to use lightblue with, simply import lightblue. Packaging with ensymble afterwards you also get lightblue module included and installed in the right place.

Hope this helps.

Would you mind publishing this ensymble simplesis [...] command, please? :-)

I want to install all files in the C:.

ok, on further investigating python shell, i noticed the E:\Python\Lib folder! so you can manually create this path and .py wrappers will be automatically detected

to package your extension, create the folder structure as shown:

lightblue
  |
   -- sys
  |    |
  |     -- bin
  |         |
  |          -- kf_lightblueutil.pyd
  | 
   -- python
       |
        -- Lib
            |
             -- all the .py files

the ensymble command i use is from the command prompt (assuming lightblue folder above is created in C:\program files\pythonfors60\module-repo\):

C:\PROGRA~1\PYTHON~1\module-repo>c:\python25\python ..\ensymble.py simplesis -u
0xUID -r 0.0.4 -c "lightblue" lightblue

replace the parts in bold as required. hope that works for you!

Thanks to the86hitman! I finally figured out how to create lightblue.sis based on his info.
In the following (long explanation) I show You how to create your own module to be imported
in your applications, and how to create a working lightblue.sis file to be installed on a
phone wiht PyS60 1.9.x
Hope it works for you

CREATE A MODULE TO USE WITH YOUR .SIS FILES:
--------------------------------------------

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
mymodule.py:
------------
import appuifw, e32, sys, os, sysinfo # Test various imports

def test():
print "MyModule test OK"
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
testMyModule.py:
----------------
import mymodule

mymodule.test()
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%


Create the following folder structure (This is for PyS60 1.9.x)
If you don't know how the folder structure is on your phone, you can
use the following commands in the ScriptShell's interactive console:
___________________________________________________________
import os

os.listdir("c:") # to see if you have the resource directory
os.listdir("c:\\resource")
# If you have the c:\\resource\\python25 folder structure on
# the phone, then use the following folder structure on you PC.
___________________________________________________________

module-repo
  |
  |
  |__ mymodule
        |
        |
        |__ sys
        |    |
        |    |__ bin (.pyd here. If any)
        |
        |
        |__ resource
             |
             |__ python25 (place .py files here)

Put mymodule.py in
C:\Program Files\PythonForS60\module-repo\mymodule\resource\python25 folder
and nothing in
C:\Program Files\PythonForS60\module-repo\mymodule\sys\bin (we have no .pyd file)

Go to C:\Program Files\PythonForS60\module-repo with a command prompt and write

ensymble.py simplesis -u 0xa1234567 -r 0.0.7 -c "mymodule" mymod

This will create mymod_v0_0_7.sis
Install this file on your phone.

Now use the "PyS60 application packager" to create testMyModule_v1_0_0.sis or use
what ever way you normally create .sis files. Install testMyModule on the phone.
Go to your program folder on the phone and run testMyModule. This will print:

MyModule test OK

That's it.

CREATE lightblue.sis TO IMPORT IN YOUR APPLICATIONS:
----------------------------------------------------

Use os.list as described above to determine the folder structure on the mobile phone.
On my phone the .pyd file are located in c:\\sys\\bin and .py files located in
c:\\resource\\python25

You can maby best determine where to install the module files by using a program like SISXplorer.
I used SISXplorer to open wlantools.sis for PyS60 1.9.x. I know that this version of wlantools runs
fine with my PyS60 1.9.7 installation. In SISXplorer you can see where the .pyd file and .py files
are installed. It says something like this:

EOpInstall( "!:\sys\bin\kf_wlantools.pyd" );
EOpInstall( "c:\resource\python25\wlantools.py" );

We can now create the needed folder structure in C:\Program Files\PythonForS60\module-repo (in my case)

module-repo
  |
  |
  |__ lightblue
        |
        |
        |__ sys
        |    |
        |    |__ bin ( kf__lightblueutil.pyd )
        |
        |
        |__ resource
             |
             |__ python25 ( __init__.py         )
                          ( lightblue.py        )
                          ( _lightbluecommon.py )
                          ( obex.py             )
                          ( _obex.py            )
                          ( _obexcommon.py      )

IMPORTANT NOTE: When You download lightblue-0.4_s60-3rdEd-FP2_PyS60-1.9.x.zip the archive contain
                _lightblue.py. RENAME this file to lightblue.py
                If You don't rename the file, You will get a "no module named lightblue" error when
                you try to import lightblue in your application.

Go to C:\Program Files\PythonForS60\module-repo with a command-line tool and write:

ensymble.py simplesis -u 0xa1234567 -r 0.0.7 -c "lightblue" lightblue

This will create lightblue_v0_0_7.sis
Install this file on your phone.

Using SISXplorer to open lightblue_v0_0_7.sis I can now see the following:

EOpInstall( "!:\sys\bin\kf__lightblueutil.pyd" );
EOpInstall( "!:\resource\python25\_lightbluecommon.py" );
EOpInstall( "!:\resource\python25\_obexcommon.py" );
EOpInstall( "!:\resource\python25\obex.py" );
EOpInstall( "!:\resource\python25\_obex.py" );
EOpInstall( "!:\resource\python25\lightblue.py" );
EOpInstall( "!:\resource\python25\__init__.py" );

That's it. I can now import lightblue to an application as follows:

import lightblue

devices = lightblue.finddevices(getnames=True)

for device, name, dev_id in devices:
	print "----------------"
	print "Device: " + device
	print "Name: " + name
	print "Dev_id: " + str(dev_id)

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

To finnsmama - I got the same error as you did at some point (can't find the module _lightblueutil).
It seems to be the kf__lightblueutil.pyd - If you look at other dev-modules they have a similar
construct. With the camera module the .pyd file is called kf__camera.pyd and the camera.py uses import _camera. So I think the error is caused because the module .py file can't find the .pyd file.

Hi TueChristophersen

Thank you for the recipe!
I followed your guideline for creating the lightblue.sis but I get the following output:

ensymble.py: warning: no certificate given, using insecure built-in one
Input files resource/python25/lightblue.py resource/python25/obex.py resource/python25/_lightbluecommon.py resource/python25/_obex.py resource/python25/_obexcommon.py resource/python25/__init__.py sys/bin/kf__lightblueutil.pyd

Any ideas what goes wrong?
I've tried both the lightblue-0.4_s60-3rdEd-FP2_PyS60-1.9.x.zip and lightblue-0.4_s60-3rdEd-FP2_freedevcert_PyS60-1.9.x.zip versions.

Many thanks!
