sorry, but I didn't check - I only have x86{,_64} hardware

[lykkedk]

  Cool...

I think i have to ask Bela' if he has any intention of building pygobject.

I try to build it, but there as dep. on dep. on dep. on it 

Rgds; Jesper.

pygobject.tcz added to repo.

[lykkedk]

  Thanks Bela'

Nice nice!

I am missing something / something setup uncorrect? I Donno?

Have this error, even when pygobject is loaded

tc@PlayBox:~/bluez-4.101/test$ sudo python simple-agent
Traceback (most recent call last):
  File "simple-agent", line 5, in <module>
    from gi.repository import GObject
ImportError: No module named gi.repository

[bmarkus]

No idea what is simple-agent. Importing module in Python works:

Code: [Select]

tc@box:~$ python
Python 2.7.9 (default, Dec 27 2014, 09:00:34)
[GCC 4.9.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from gi.repository import GObject

I think you need pygobject-2.x rather than pygobject-3.x for bluez-4

[lykkedk]

Bela' ::

The simple-agent, is a tool for pairing bluetooth devices supplied with the BlueZ4 package.

Look, when i try the same :

tc@PlayBox:~/bluez-4.101/test$ python
Python 2.7.9 (default, Dec 27 2014, 09:00:34)
[GCC 4.9.2] on linux2

>>> from gi.repository import GObject
Traceback (most recent call last):

Juanito :: You might be right... Gobject must maybee be 2 instead of 3

Bela'

Can you try this on your devel. machine ?

Hi.

tce-load -i pygobject.tcz did the trick!

Sry... i thought that when loading the pygobject-dev package, it would load the pygobject package.

 

Rgds; Jesper.

[bmarkus]

Sry... i thought that when loading the pygobject-dev package, it would load the pygobject package.

I does, but there was a typo in the dep file which was corrected and now ok. You were too fast.

[lykkedk]

Okay then.

I have desided to use Bluez4 for bluetooth streaming, cause bluez4 does support ALSA, which the new Bluez5 doesent.

I tried and succeded compiling bluez5, and pulseaudio with the bluez5 enabled. -Problem is, that pulseaudio uses way to much cpu power.
-anyway i never succeded streaming audio on bluez5.

So status now is :

Compiled and created bluez4-a.tcz (the -a is just for my own sake)
patched the .tcz file with the following : <allow send_type="method_call"/>, according to this : http://thethingsystem.com/dev/Bootstrapping-the-Raspberry-Pi.html

<policy user="root">
    <allow own="org.bluez"/>
    <allow send_destination="org.bluez"/>
    <allow send_interface="org.bluez.Agent"/>
    <allow send_interface="org.bluez.HandsfreeAgent"/>
    <allow send_interface="org.bluez.MediaEndpoint"/>
    <allow send_interface="org.bluez.MediaPlayer"/>
    <allow send_interface="org.bluez.Watcher"/>
    <allow send_interface="org.bluez.ThermometerWatcher"/>
    <allow send_type="method_call"/>
  </policy>

I can start bluetoothd, and a bluetoothd --version gives me following :

tc@PlayBox:~/bluez-4.101/test$ bluetoothd --version
4.101

Top returns :

So next step is to have the bluez4 scripts running (python)

A bluetooth scan seems to work 

tc@PlayBox:~$ sudo hciconfig hci0 up
tc@PlayBox:~$ sudo hcitool scan

But for pairing i need the tools inside the bluez4 package.

This is here i am fighting the python.

tc@PlayBox:~/bluez-4.101/test$ ls
agent.c             hciemu.1            lmptest.c           service-did.xml     simple-service      test-input          test-serial-proxy

avtest.c            hsmicro             mpris-player.c      service-opp.xml     test-attrib         test-nap            test-telephony

bdaddr.c            hstest.c            rctest.c            service-spp.xml     test-device         test-oob            test-thermometer
btiotest.c          ipctest.c           sap-client          simple-agent        test-discovery      test-proximity      uuidtest.c
dbusdef.py          l2test.c            scotest.c           simple-endpoint     test-health         test-sap-server
gaptest.c           list-devices        sdptest.c           simple-player       test-health-sink    test-serial

So when trying to start e.g simple-agent i got :

tc@PlayBox:~/bluez-4.101/test$ python simple-agent
Traceback (most recent call last):
  File "simple-agent", line 5, in <module>
    from gi.repository import GObject
  File "/usr/local/lib/python2.7/site-packages/gi/__init__.py", line 27, in <module>
    from ._gi import _API
ImportError: libgirepository-1.0.so.1: cannot open shared object file: No such file or directory

It's hard to get going 

Rgds; and goodmorning Jesper

[Juanito]

libgirepository-1.0.so.1 is provided by gobject-introspection, which is a dep of pygobject.
