S2-LP Parameters configuration

[LPrat.3]

Could someone help to understand the better value to use at frequency deviation, considering at bellow specs:

 

#define BASE_FREQUENCY 916000000 //Hz
#define MODULATION_SELECT MOD_2GFSK_BT05
#define DATARATE 38400 //bps
#define FREQ_DEVIATION ?????
#define BANDWIDTH 100000 //Hz
#define CHANNEL_SPACE 180000  //Hz

 

A higher frequency deviation means that easier to read data from another devices (if frequency of devices drift)?

 

Best regards
