CC1101_MDMCFG2
[6:4] MOD_FORMAT[2:0]
The modulation format of the radio signal ASK is only supported for output powers up to -1 dBm MSK is only supported for datarates above 26 kBaud
Values:
0 : 2-FSK
1 : GFSK
3 : ASK/OOK
4 : 4-FSK
7 : MSK
[2:0] SYNC_MODE[2:0]
Combined sync-word qualifier mode. The values 0 (000) and 4 (100) disables preamble and sync word transmission in TX and preamble and sync word detection in RX. The values 1 (001), 2 (010), 5 (101) and 6 (110) enables 16-bit sync word transmission in TX and 16-bits sync word detection in RX. Only 15 of 16 bits need to match in RX when using setting 1 (001) or 5 (101). The values 3 (011) and 7 (111) enables repeated sync word transmission in TX and 32-bits sync word detection in RX (only 30 of 32 bits need to match).
Values:
0 : No preamble/sync
1 : 15/16 sync word bits detected
2 : 16/16 sync word bits detected
3 : 30/32 sync word bits detected
4 : No preamble/sync, carrier-sense above threshold
5 : 15/16 + carrier-sense above threshold
6 : 16/16 + carrier-sense above threshold
7 : 30/32 + carrier-sense above threshold
