...Finally the "toy" has arrived and i found one hour to play with it.

After some issue, now all is working quite well.
If someone else has issues, i would suggest to pair the Liveview with an Android phone, clean the maemo association and then retry...

I'm using bluez 4.99 and the LiveViewServer.py from the first post.
I have updated the firmware using dfu-util and the firmware bin found here:
https://code.google.com/p/openliveview/downloads/list

Stock firmware has md5:
1d40b9027c030c36a5b2b515b4a0577a
and running:
strings firmware.bin| grep SWID:
SWID:1243-1288SWRV:1.0.A.0.8

While the one from the webpage of openliveview has md5:
82ec0697417294b6eb81b351ca0e0f03
and running:
strings firmware.bin| grep SWID:
SWID:1243-1288SWRV:1.0.A.0.16
