Writing updated time on the RTC clock

sudo timedatectl set-ntp true //wait for couple of second to sync ntp time
sudo hwclock -r
sudo hwclock -w
sudo timedatectl set-ntp false

Install Socat

sudo apt-get install socat

Example usage of socat

sudo socat pty,link=/dev/ttyTCP0,ignoreeof,user=pi,group=dialout,mode=777,raw,echo=0 tcp:10.10.0.211:23 &

The above creates a virtual serial port /dev/ttyTCP0

To Listen to socat traffic:

ss -l

Steps on how to auto start socat to create a virtual port named /dev/ttyESP0

First create scripts that will run rigctld, rotctld and socat at bootup:
(note that & stands for backgrounding)

sudo nano /home/pi/autorig.sh

#!/bin/bash
rigctld -m 344 -r /dev/ttyUSB0 -t 4532 -s 19200 &

save

sudo nano /home/pi/autorot.sh
#!/bin/bash   
sleep 3 && rotctld -m 202 -r /dev/ttyESP0 -t 4533 -s 19200 -C timeout=500 -vvv

save

sudo nano /home/pi/autosocat.sh
#!/bin/bash   
sudo socat pty,link=/dev/ttyESP0,ignoreeof,user=pi,group=dialout,mode=777,raw,echo=0 tcp:192.168.1.51:23,forever,keepalive,keepidle=10,keepintvl=10,keepcnt=4 &

save

Don't forget to make the script executable by:

chmod +x autorig.sh
chmod +x autorot.sh
chmod +x autosocat.sh

To check:

ls -l

You will see these 3 scripts now turned to green. (executable file)

Very handy script to stop any rotctld and rigctld processes.

sudo nano /home/pi/stoprigrot.sh
#!/bin/bash

# finds rigctl and rotctl PIDs and SIGTERMs them
# Michael Hirsch

RigPID=$(pgrep rigctld)
RotPID=$(pgrep rotctld)

[ -n $RigPID ](/jharwinbarrozo/rotcontrol/wiki/--n-$RigPID-) && { echo "Stopping rigctld PID $RigPID"; kill $RigPID; }

[ -n $RotPID ](/jharwinbarrozo/rotcontrol/wiki/--n-$RotPID-) && { echo "Stopping rotctld PID $RotPID"; kill $RotPID; }

save

How to run this stoprigrot - just bash it :) Do it twice! So you would know if there's any other duplicate processes you are not aware of.

bash /home/pi/stoprigrot.sh

===========================

sudo nano /etc/xdg/lxsession/LXDE-pi/autostart

@lxpanel --profile LXDE-pi
@pcmanfm --desktop --profile LXDE-pi
@xscreensaver -no-splash
@/home/pi/autorigrot.sh
@gpredict
point-rpi

===========================

Gpredict

  1. Create a rotator module
    Name: ESP-LINK
    Host: localhost
    Port: 4533
    Min az: 0 Max az: 360
    Min el: 0 Max el: 90

  2. Create a radio module (if you haven't done this yet)
    Name: IC910H
    Host: localhost
    Port: 4532
    Radio type: IC-910 *you can only see this option if you modified, build from source the rigcontrol repo
    PTT status: None
    VFO Up/Down: Not applicable
    LO down: 0 Lo up: 0
    Signalling AOS LOS both unchecked

To monitor Gpredict log:

tail -f /home/pi/.config/Gpredict/logs/gpredict.log

Connect to the already running rotctld, and set position to 135.0 degrees azimuth and 30.0 degrees elevation with a 1 second read timeout from the shell prompt:

echo "\set_pos 135.0 30.0" | nc -w 1 localhost 4533
