Calypso-BTS: State of Art and Future Improvements

Hey folks,
Since I am planning to delve deeper into the Calypso-BTS...

I was wondering if.... after Sylvain and Jolly's last commits into their "*/testing" branches [1][2]... 
 - Someone else have made some (private) changes/improvements to the sources?!
 - Is there a TO DO list available for suggested improvements?
 - Is anyone working on it or it would be interested?
 
And another question... why those branches have not been merged?

Cheers,
Luca

Hi,

> And another question... why those branches have not been merged?

Because there is a bug that breaks the normal "phone" function in the
DSP patch. In theory the patch shouldn't do anything if not
explicitely enabled via a control bit in the DSP API zone, but in
practice, it prevents sync/power detection from working for some
reason.

Never had the motivation to trace out the bug, (or finish the dsp
patch to support multiple timeslots like it was designed to for that
matter).

Cheers,

   Sylvain

Yes, I saw that.

But it's not a fix, it's a workaround that passes a 1 or 0 across like
4 abstraction levels to load the patch or not depending on wether
you'll need it ...

Cheers,
