Question

The question has been asked whether the Baseband bitstream is differentially encoded before goes through the Guassian low pass filter in the bluetooth transmitter?

Answer

The Answer is no, as in the core spec, there is a bitstream process scheme, no differentially encode process exists. And since GFSK is used, it isn't necessary to use differentially encoded code.
