Sync time with NTP for app_rpt

(internet connected systems only)

While this probably should be done by your OS, from cron

Here is a script to sync your time with NTP.

Give  it a name (synctime.sh) , Apply ownership

Give it a command in rpt.conf, Run that command  from the macro/sched late at night.

#!/bin/bash
/usr/sbin/ntpdate pool.ntp.org > /etc/asterisk/log/timelog.txt

Will also create a log file if you need to check that it has been running correctly.
If not needed, delete all after and including ">"
Hopefully these are more of a example of how to do other things for those that are learning.

Macro Delay Execution Timer

This script was created to execute a  delay then a command.

Meaning that you issue a command as part of some other simple or complex function and have a delay before it executes a second part or a cancellation of the same.

It could have a multitude of applications once you understand what it is actually doing. But for our example here, it is a simple one.

Our example, we have a light that we use to light our way from the repeater site at night and often someone using it for access to or from the repeater site at night forgets to turn it off. So we need a auto-turn-off for this light-up function.

First,

We are calling the script macro-cmd-timer.sh

If you are using this for many things or nodes, make each instance a unique name with node number and/or special function name.

Create a command for the script in rpt.conf

XXXX=cmd, etc/asterisk/myscripts/macro-cmd-timer.sh

Now our macro for calling the “turn light on” looks like this before we start:

[macro-29283]

55= *9987 *9988# ; (play file” light-on” and switch parallel port pin 5 on)

56= *9989 *9990# ; (play file “light-off” and switch par port pin 5 off)

After:

55= *9987 *9988 *XXXX# ;insert your script command issued above

Edit the script and set the timer in seconds and call the macro that turns it off when the timer has expired.

Make the script 775 ownership.

DOWNLOAD as a file

#!/bin/bash
# mike/kb8jnm – macro-cmd-timer.sh
# create delay / run command
# make a command for this script, call it from a macro string
# set wait time in seconds
sleep 1200
# execute command (calling a macro to shut off the called function)
# format is – rpt fun NODE# CMD#
asterisk -rx “rpt fun 29283 *556”
# will clean exit after waiting and executing

# end of file EOF

This simple example is just to show functionality. Use your imagination to fit your need.  Be careful not to put it in a situation where it could be called multiple times in automation.

Barry, G8SAU Used it for this…

I have made a repeater mast head pre-amp control
that users can enable turn on with a DTMF code  eg *51 that gives a boost 
to the RX for a period of 30 mins then reverts to OFF

for those moments that need extra coverage on RX when Fixed user is working 
a Mobile user or an HT user on the edge of coverage, RX wise.

Script – Initial ID / Normal ID

Many of us that are use to the older premium  “hard-wire” style repeater controller are also use to having a initial ID that would allow for a separate ID to be played when the repeater was keyed for the first time from a sleep state.

Then afterwards, would play a normal ID at “id-interval” timing that would be a short ID for in-use.

Most of us would use that Initial ID to play a long ID stating extended info about the repeater like location information so when someone stumbled on the repeater late at night or when nobody was around to ask, they would have the correct info about which repeater they were accessing and where it was.

While there was limited ways to accurately obtain this info and act on it in a way that was uncomplicated for a control-op to install correctly and use, I took it to task.

This is totally a Bash Script that needs to be run from start-up
or from a command line (should do for testing beforehand).
Made/Tested with ACID.

Here is the result.

You need two audio files of the ID's before you start.
Here called "idmsg1" (initial/sleep id)
& "idmsg2" (wake/regular id) and 
our actual id message is "idmsg"
You can just take one of those files and copy ( cp ) it to a new filename for idmsg 
like this:  cp idmsg1.wav idmsg.wav
(assuming you are in the directory of the files)


I'll call the shell script init-id.sh
If running multi-nodes on a single server, you might want to make a new filename like:
init-id-29283.sh
init-id-29284.sh
so you can have separate id's for each nodes.
This would mean making a script for each node and running a new process for each.
If you do this, change the /tmp/init-id.txt located in "two places" in the
file to the same unique format.

In rpt.conf
You need to give it a command:ex
909804=cmd,/etc/asterisk/myscripts/init-id-29283.sh

Use the startup macro to call it:ex
startup_macro=*9401,*9410,*909804

You need to edit before running:
Node number
files and locations of your 2 id files and the /location/name of your voice-id file
(idrecording =/etc/asterisk/msg/idmsg) in both locations in the script.
Pay close attention to spaces when editing as it will change things in error.

Make the files & script we are using 775 ownership

"DO" RUN THIS FROM A COMMAND LINE FOR TEST BEFORE LOADING FROM rpt.conf
(from a shell)
cd /etc/asterisk/myscripts (where located)
./init-id-29283.sh  ( ./ with actual name you use .sh)
and you use <ctrl> + C to break and stop it from command line running it.
change sleep number to 20 for command line testing and 200 when auto
loading to limit file accesses. 
I'm Assuming a 5 minute or better id interval.

Do pay close attention to spaces in the file when editing.
You will create errors if not and not understand where from.

At the bottom of this page is shown what the response will look like from a command line.

When needed, the script simply 
copies idmsg1 to idmsg (sleep/init-id)
or
copies idmsg2 to idmsg (wake/normal-id)
But will not attempt to write while ID is playing. ider_state=0

#!/bin/bash
# init-id.sh - mike/kb8jnm
# overwrite id files to create initial id & regular id
# based on app_rpt - "ider_state" variable.
#
# make ownership of this file 775
#
# -See sleep ### at the bottom is in seconds.
# Lower the value to 20 for testing live from a command line.
# You will see the updates faster.
#

# preset some parms
idis='wakeid'

# this is a infinate loop
while :
do

# read our parms for node - put in text file - (edit node number)
 asterisk -rx "rpt xnode 29283" > /tmp/init-id-29283.txt

# parse our parms from that file and only rewrite id if it needs it
 while read line
 do
 echo $line
 idsleep='ider_state=2'
 idwake='ider_state=1'

 if [ "$line" = "$idsleep" ] && [ "$idis" = "wakeid" ]; then
# edit locations and names next line
 cp /etc/asterisk/msg/idmsg1.wav /etc/asterisk/msg/idmsg.wav
 echo " ** " $line $idsleep "-init ID"
 idis='sleepid'
 fi
 if [ "$line" = "$idwake" ] && [ "$idis" = "sleepid" ]; then
# edit locations and names next line
 cp /etc/asterisk/msg/idmsg2.wav /etc/asterisk/msg/idmsg.wav
 echo " ** " $line $idwake "-normal ID"
 idis='wakeid'
 fi
 done </tmp/init-id-29283.txt

# show status if running from a command line for test
echo "ID IS " $idis

# wait a bit to limit file access (in seconds)
sleep 200

done


If everything is working fine, 
you will see something like this at a command line
when you execute it:


RPT_NUMLINKS=1     ;these are parms returned by app_rpt on xnode
RPT_LINKS=1,T41715
RPT_NUMALINKS=1
RPT_ALINKS=1,41715TU
RPT_AUTOPATCHUP=0
RPT_ETXKEYED=0
RPT_TXKEYED=0
RPT_RXKEYED=0

parrot_ena=0
sys_ena=1
tot_ena=1
link_ena=1
patch_ena=1
patch_state=4
sch_ena=1
user_funs=1
tail_type=0
iconns=1
tot_state=2
ider_state=2       ;when our script sees this line it acts.
 **  ider_state=2 ider_state=2 -init ID     ;these are echos of internal vars
tel_mode=2

ID IS  sleepid      ;this is a echo of internal var of current state.

Don't forget to check your timers...
totime=600000 ;in milisoconds 300000=5min
idtime=590000 ; in 10ms
politeid=500000 ; =8m20s
sleeptime=1830 ;in seconds 300=5m
