SX1278 Receive in OOK/Continuous mode

[Camerart]

Hi,
Can anyone point me to clues for setting SX1278 Module for RX in OOK/Continuous mode.  I think RSSI is used, but 1/ Which PIN is used for RX?  Is it The DATA PIN or is it actually continuous, as in it could be heard with an earphone?
Cheers, Camerart
