ACARSDEC 4.0 update needs --soapysdr=

[AndrewMohawk]

Heya,

In this update: ed85121

It appears that ACARS_CMD+=("-d" "$SOAPYSDR") has been replaced by just ACARS_CMD+=("$SOAPYSDR") however it appears that the option should be --soapysdr from looking at acarsdec --help:

Usage: acarsdec  [-t secs] [-A] [-b 'labels,..'] [-e] [-i station_id] [--statsd host=ip,port=1234] --output FORMAT:DESTINATION:PARAMS [--output ...] [--skip-reassembly] [ [rtlopts] | [airspyopts] | [soapyopts] <f1> [<f2> [...]] ]

 <f1> [<f2> [...]] are given in decimal MHz, e.g. 131.525

 -i <stationid>         : station id used in acarsdec network format (default: hostname)
 -A                     : don't output uplink messages (ie : only aircraft messages)
 -e                     : don't output empty messages (ie : _d,Q0, etc ...)
 -b <filter>            : filter output by label (ex: -b "H1:Q0" : only output messages  with label H1 or Q0)
 -t <seconds>           : set forget time (TTL) to <seconds> for flight routes (affects monitor and routejson, default: 600)
 --skip-reassembly      : disable reassembling fragmented ACARS messages
 --statsd host=<myhost>,port=<1234>     : enable statsd reporting to host <myhost> on port <1234>

 Use "--output help" for available output options

 Available inputs:

 rtlopts:
 --rtlsdr <device>      : decode from rtl dongle number <device> or S/N <device>
 -g <gain>              : set rtl gain in db (0 to 49.6; >52 and -10 will result in AGC; default is AGC)
 -p <ppm>               : set rtl ppm frequency correction (default: 0)
 -m <rateMult>          : set rtl sample rate multiplier: 160 for 2 MS/s or 192 for 2.4 MS/s (default: 160)
 -B <bias>              : enable (1) or disable (0) the bias tee (default is 0)
 -c <freq>              : set center frequency to tune to in MHz, e.g. 131.800 (default: automatic)

 airspyopts:
 --airspy <device>      : decode from airspy dongle number <device> or hex serial <device>
 -g <linearity_gain>    : set linearity gain [0-21] (default: 18)

 soapyopts:
 --soapysdr <params>    : decode from a SoapySDR designed by device_string <params>
 -g <gain>              : set gain in db (-10 will result in AGC; default is AGC)
 -p <ppm>               : set ppm frequency correction (default: 0)
 -c <freq>              : set center frequency to tune to in MHz, e.g. 131.800 (default: automatic)
 -m <rateMult>          : set sample rate multiplier: 160 for 2 MS/s or 192 for 2.4 MS/s (default: 160)
 -a <antenna>           : set antenna port to use (default: soapy default)

I dont want to just do the change because it would break backward compatibility, what I have done to resolve this on my side is to change the selection to:

SOAPYSDR: --soapysdr=rtlsdr,serial=${ACARS_RTL_SERIAL2}

otherwise you will get an error Missing input similar to this:
