[solved] LIRC CommandIR Blaster - Channel Change Problems

[ColeSlaw]

I'm having problems with my channel change script. I'm using a commandir IR blaster. I seem to have everything complied correctly and working. I can send commands to the Dish Network box that I have and it receives them. My problem comes when I try to send a three digit channel number. The first one and sometimes two digits get read, but then the third digit never gets read and it goes to the lowest available channel.

My lircd.conf file is off of the MythTV wiki:

# Each has been implemented in this config file with the remote names "dish#"
# where the hash/pound/number sign ("#") is a code number from 1 through 16.
# There is also a remote called "dish" (without a number), for users with only
# one receiver, that uses remote code 1 (DISH's default).
#
# The duty_cycle (the percentage of time during a pulse that infrared light is
# being sent) is commented because some hardware transmitters don't support its
# use.
#
# The discrete power functions (power_on and power_off) can be used to ensure
# the power state of the receiver.  However, they probably shouldn't be used in
# a channel change script as the receiver will require a significant delay
# after a power_on before it is capable of receiving/responding to additional
# commands (such as channel numbers).  Instead, assuming most of your recording
# is during prime-time, you may want to set a cron job to run a "power_on"
# command for each of your receivers about 5 or 10 minutes before primtetime.

I got the script from CommandIR. I have tried changing the default delay number inside the script, but it doesn't seem to help.

Code: Select all

#!/bin/sh
# Maintained by CommandIR Support mini at commandir.com - Comments / Suggestions Welcome.
if [ $# -lt 3 ]
then
  echo "IR Control Script for LIRC V2.0
Includes support for CommandIR transmitter selection and lockfile.

Usage:
$0 REMOTE_NAME TRANSMITTER_NUM (CHANNEL_NUMBER | IR_COMMAND) [DELAY]

Sends an IR command or sequence of numbers using REMOTE_NAME via emitter
TRANSMITTER_NUM.  DELAY (in seconds) is waited between sending IR commands.

Example:  Change ExpressVu to channel 123 using emitter 2 with a 0.3s pause between digits:
$0 expressvu 2 123 .3
"
  exit 1
fi

if [ $# -eq 4 ]
then
 DELAY=$4
else
 DELAY=.3
fi

LOCKFILE=/tmp/lirclock
export PATH=/bin:/usr/bin:/usr/local/bin
REMOTE_NAME=$1
TRANSMITTER=$2
cmd="$3"

while [ -f $LOCKFILE ]
do
#echo "Waiting for lock..."
  sleep .1
done

touch $LOCKFILE

irsend SET_TRANSMITTERS $TRANSMITTER
sleep .15
case $cmd in
    [0-9]*)
    for digit in $(echo $3 | sed -e 's/./& /g'); do
        irsend SEND_ONCE $REMOTE_NAME $digit
        sleep $DELAY
    done
    ;;

    *)
        irsend SEND_ONCE $REMOTE_NAME $cmd
        ;;
esac

rm $LOCKFILE

I have tested lircd by manually inputting the following:

Code: Select all

irsend send_once dish1 5

This command works every time. If I can type fast enough, it even changes channels. I then try the channel change script, the first two numbers will come through and the third never makes it.

Code: Select all

./chchange-device-lock.sh dish1 1 122

Anybody that can help, it is greatly appreciated.

I feel like an idiot replying to my own post so quickly. I kept trying channel 122. After I switched to trying channel 120, I noticed that the two numbers coming across were 10. It was going too fast to read the middle one. I increased my delay to .5 and now it works flawlessly everytime.

My bad
