Hello everyone!  
I saw online they released an updated version of GMSK demod called  
“Enhanced GMSK”. I just want to double check if the GMSK demod in 3.4.3.  
version is the enhanced one?  
Also I wonder if there is any parameter related with BT in the GMSK  
demod? What are the formulas for MM clock recovery like “mu”, “omega”?  
Thanks in advance 🙂
