LimeSDR-Mini with gr-dect2

Why does LimeSDR-Mini not work with gr-dect2 ?

I tried with gr-limesdr, uhd, soapy … I still have nothing.
I take osmocom sources, usrp sources, rtlsdr, limesdr rx and I still have nothing despite that there is no error and that grc starts well.

I tried a lot of configuration in grc, I do not know what to do, someone has ideas to make the LimeSDR-Mini.grc ?

With hackrf, first try and it works without problem. Limesdr should do it too without difficulty, right ?

Can’t see why not and likely to be some simple configuration issue. A good place to ask might be the GNU Radio list.
