I have a PVR-250. I have a IR blaster that I got from http://www.irblaster.info/. I have it connected to my cable box, a Scientific Atlanta Explorer 3100HD.

When I first setup my myth box, I used the instructions from http://mirror.mmdsi.com/losdos.dyndns.o ... _LIRC.html which worked great under R5A16.

I decided to upgrade to R5C7. Since the upgrade, many things work fine, but there are a couple that do not.

One problem is I can't get the IR blaster to work anymore. If I press the channel up or down buttons, it thinks it's changing the channel (the on screen display indicates a change), but it doesn't actually work.

I followed the instructions at:

http://mysettopbox.tv/phpBB2/viewtopic. ... =irblaster

It says I shouldn't need to since I have R5C7, but I went through them again, just to be sure.

I checked out

/etc/irblaster/channel_change.sh
/etc/irblaster/hardware.conf
/etc/irblaster/irblasterd.conf

and all 3 seem to be fine.

When I try:

/etc/irblaster/channel_change.sh 10

I get:

/usr/bin/irsend: could not connect to socket
/usr/bin/irsend: No such file or directory
/usr/bin/irsend: could not connect to socket
/usr/bin/irsend: No such file or directory

I've been searching the forums, and I can't seem to find an answer for this.

Thanks in advance for any help you can give.

The "could not connect to socket" means irsend couldnt talk to the irblasterd instance of the lircd deamon. Perhaps it is not running for some reason. As root, run and then check that irblasterd is running by typing

When I run

/etc/init.d/irblaster start

as root, I get:

bash: /etc/init.d/irblaster: Permission denied

When I run

ps aux | grep irblasterd

I get:

root 5713 0.0 0.1 1644 504 ttyp0 S+ 20:27 0:00 grep irblasterd

For some reason it appears your /etc/init.d/irblaster script is not executable. Make it so:rinse and repeat.

Our good old friend chmod.

Now when running:

/etc/init.d/irblaster start

I get:

What did you do to /etc/init.d/irblaster? First of all, it should have been executable, so the fact that it wasnt is a concern. Secondly, your last post seems to indicate that it is monumentally cocked up.

I don't remember doing anything to /etc/init.d/irblaster. It is definitely a mess, though

Suggestions on how to best clean this up?

Get a copy from that thread you pointed to. Make sure that your method of copying it from that thread does not put a space on the end of every line since this will break the application of any continuation characters (\) on the end of lines. Make sure that the script that you end up with has unix style line endings not DOS style.

Yeah, I checked the first couple lines he had trouble with and they're both continutation lines. Perhaps a bit of shell magic to clean up the file...

So, I cleaned up /etc/init.d/irblaster using tjc's script (thanks, btw).

Now when I try testing with /etc/irblaster/change_channel.sh, it sends all sorts of weird commands to my cable box, one after the other: turning it off and on, entering in different channel numbers, and activating other commands.

And when I try just choosing "Watch TV" from the main MythTV menu, it does something similar: turns off my cable box, turns it back on, activates the "Bypass", and turns it off again.

I'm going to look back through any other files I've touched to see if something similar is going on, but any pointers would be much appreciated.

Sounds like you've got the wrong codes configured. You got to set it up to use the appropriate ones for you type of device. Look under /usr/local/share/knoppmyth/remotes/irblaster for some examples.

That makes sense, but it's the same file I used under R5A16 without a problem.

I'll take another look at it and see if something's changed.

So after trying different things to get it to work, I ended up just starting over. I did another install of R5C7 (via the upgrade option).

I chose the options at startup for my Hauppauge PVR-250. I chose having a serial blaster, but said I would put in the info later as my cable box wasn't listed.

I copied the file for my cable box to /etc/irblaster/irblasterd.conf.

I tried testing /etc/irblaster/channel_change.sh. No luck. I tried removing the trailing space after the slash after "REMOTE NAME" in the script. Still no luck.

My Hauppauge remote works fine to control mythtv, but the IR blaster is not passing the commands to my cable box. It thinks it's changing the channel, but it just pauses for second, updates the on screen channel info, and stays on the same channel.

Maybe the irblasterd.conf file which worked fine under R5A16 is no longer good? I can look around for another version. Any other suggestions?

Also, and I'm not sure if this is related or not, when I choose "Watch TV" from the main menu, it pauses for about 15 seconds before displaying TV, where it used to only be a few seconds.

Does the channel change when running the channel_change.sh script at the command line?

If not, can you get the irblaster to do anythying using the irsend command?

Post up you change channel script. I had the same problem and I had to add a small delay then send the ok command for the channel to actually change. For example if I get my digital cable remote and am on channel 20 then hit 33 I will se 33 on by box then it will go back to 20. If I hit 33 then ok it will change. You change channel script has to do the same.
