The nuclear modification factor 
and the azimuthal anisotropy coefficient 
of prompt and nonprompt (i.e. those from decays of b hadrons) mesons, measured from PbPb and pp collisions at
at the LHC, are reported. The results are presented in several event centrality intervals and several kinematic regions, for transverse momenta 
and rapidity 
, extending down to 
in the 
range. The of prompt is found to be nonzero, but with no strong dependence on centrality, rapidity, or 
over the full kinematic range studied. The measured of nonprompt is consistent with zero. The of prompt exhibits a suppression that increases from peripheral to central collisions but does not vary strongly as a function of either y or in the fiducial range. The nonprompt
shows a suppression which becomes stronger as rapidity or increases. The and of open and hidden charm, and of open charm and beauty, are compared.
