Hello,

I have tried to compile gr-bluetooth (version obtained by git clone  
git://gr-bluetooth.git.sourceforge.net/gitroot/gr-bluetooth/gr-bluetooth),  
while I have a git version of gnuradio from Feb 3rd and I am getting  
errors during the compilation:  
In file included from bluetooth\_multi\_LAP.h:27:0,  
from bluetooth.cc:4107:  
bluetooth\_multi\_block.h:32:37: fatal error: gr\_clock\_recovery\_mm\_ff.h:  
No  
such file or directory  
I suspect gr-bluetooth was perhaps not ported to gnuradio-3.5 yet?  
Is the gr-bluetooth code being maintained at all?

Thanks,  
best regards,

Jiri

It was almost certainly not ported to 3.5. You might be able to compile  
it  
out of the box with 3.4. Otherwise, the gr\_clock\_recovery\_mm\_ff.h is now  
digital\_clock\_recovery\_mm\_ff.h.

gr-bluetooth hasn’t been actively maintained for a while, but the  
developers (me and Dominic S.) are happy to accept patches and to  
make any changes necessary for compatibility. At some point we would  
like to update the code to take advantage of stream tags, but at present  
our efforts are mostly diverted toward Project Ubertooth and libbtbb  
(the latter of which will probably also be integrated with gr-bluetooth  
at some point, replacing most of the Bluetooth-specific code).

Feel free to email us directly. You can also often find us in  
#ubertooth on [chat.freenode.net](http://chat.freenode.net).
