-To tune the SX127X OOK RSSI FIXED Threshold two values are used to determine if the threhold needs to be increased or decreased.  The first is the noise recevied between signals.  If the number of noise bits received between signals is greater than 100, then the threshold is incremented.  Second is the unparsed signals.  If an unparsed signal is received, but it has less than 20 pulses, the threhold is decremented.

If an unparsed signal is received, but it has less than 20 pulses, the threshold is decremented.
 
 The first approach is what is recommended in the SX127X datasheet, and the second is a control to lower the threshold if it is too high and incomplete signals are received.
