Hi Jeroen, the usrp blocks have public methods to do exactly that. It really looks like what you've proposed :)
Not so long ago, Martin added support for doing things like that by sending messages or stream tags to the block, too. As you haven't found a starting point yet: Here's GNU Radio's official API documentation: http://gnuradio.org/doc/doxygen/ and the gr-uhd blocks are here: http://gnuradio.org/doc/doxygen/group__uhd__blk.html http://gnuradio.org/doc/doxygen/namespacegr_1_1uhd.html Quite straightforward :) Greetings, Marcus On 08.10.2014 16:01, Boschma, J.J.
