Hi,

What is the max  possible Deviation for a particular Rx filter bandwidth.

also tell the minimum Deviation.

What is the modulation index in GFSK in this chipset.

    The minimum required RX bandwidth to ensure reception is given by:
    RX BW = Signal Bandwidth + 4*ppm Crystal * RF Frequency of Operation

    The signal bandwidth is a function of datarate and deviation. For FSK the signal bandwidth can be approximated as data rate + 2*frequency deviation (Carson’s rule).

    BT = 0.5 for GFSK.
