Parameter in der Kurzübersicht

Decode lora out of IQ-File/Pipe with exact samplerate=bandwidth
 -a <afc-speed>     follow frequency drift, 0 off (0.2), on sf<11 (0)
 -b <bandwidth>     kHz 0:7.8 1:10.4 2:15.6 3:20.8 4:31.25 5:41.7 6:62.5 7:125 8:250 9:500 (7)
 -C                 use crc on implicit header
 -c <cr>            coding rate and enable implicit header (4..8) (else from header)
 -d                 swith off collision detection (less cpu but loose stronger frames starting in weaker
 -D                 if dcd lost go on decoding until frame length limit (for external FEC or monitoring)
 -F                 max. block energy FEC off (hamming code fec remains on) (on)
 -f u8|i16|f32      IQ data format
 -g <dB>            add to measured signal level (0.0)
 -h                 this
 -i <file>          IQ-filename or pipe
 -L <x.x.x.x:destport>  as -U but AXUDPv2 with metadata for igate
                      may be repeated with same -b but different -s  after -L
 -l <len>           fixed datalen for implicit header else guess datalen from dcd
 -O <0..1>          optimize on off else automatic on sf/bw (-1)
 -s <sf>            spread factor (6..12) (12)
 -S <level>         enable squelch for low SF (0.0)
 -U <x.x.x.x:destport>  send frame in AXUDP
 -u <x.x.x.x:destport>  send raw frame bytes in udp
 -V                 very verbous
 -v                 verbous +:hamming ok, -:error, h:corrected, ~:weakest chirp replaced
                      ^:bins with maximum power sum used until fitting hamming
 -X <netid>         filter netwok-id (sync pattern), 1xx stops decode on wrong id (12)

example: sdrtst IQ output with FIR 125kHz: q 433.775 0 0 0 140000+125000,16
         sdrtst -t 127.0.0.1:1234 -i 1024000 -c sdrcfg.txt -r 250000 -s /dev/stdout -k | 
         lorarx -i /dev/stdin -f i16 -b 7 -v -L 127.0.0.1:2300 -s 12 -L 127.0.0.1:2301 -s 10
