The only piece I have left to get my MythTV box up and running is my IR Blaster. I have found two guides which seem to be very thorough but which apply to two different setups. For my setup, I do not need LIRC to operate an IR Receiver (I'm just using a wireless keyboard).

The rest of my setup:

- Hauppauge 150 MCE (no IR Blaster included)
- IR Blaster from irblaster.info on Serial COM1
- I'm trying to control a DirecTV HD box (though I will only be recording SD). The number on the Box says "H21-100"
- The remote that is operating it now is a DirecTV RC64 (Though again, I will be using my keyboard for input).
- Knoppmyth R5F27 fresh install

Here are the guides I'm trying to choose between:

http://www.knoppmythwiki.org/index.php?page=PVR150withSetTopBox
- Seems to be the most pertinent since it's tailored to Knoppmyth, but my Hauppauge 150 does not have the built in IR Blaster. If I go with this one, what steps would be different for me?

http://losdos.dyndns.org:8080/public/mythtv-info/IR-BLASTER-HOWTO.html
- Seems to be the most thorough and generic, though I'm guessing some of the steps would be a bit redundant since KP comes with LIRC and IR Blaster already configured.

Thanks.

if using the irblaster.info unit.... just su to root, and issue:

/usr/local/bin/irblaster.sh

I used that for my blaster, and it worked fine.

Just remember to work with the irblaster.conf files, etc.

The KM wiki page is a good reference, but you could then start with Step Three.

Thanks Larry,

I tried to follow his instructions but encountered a few problems.

When I run the test that he suggests in Step 5 I get the response


Which to me sounds like knoppmyth doesn't know that my IR Blaster is connected to my serial port. But I ran irblaster.sh a few times and tried it on both COM1 and COM2 and got the same result.

I also checked to see what was in irsend and it was total gibberish, so I'm guessing that is generated dynamically? Yes?

Also the file /etc/lirc/lircd.conf was empty, said "Unconfigured" and pointed me to the README. So I downloaded the lircd.conf file referred to in Step 2 of the wiki. Was that a good idea or a bad idea?

Any response will be greatly appreciated.

Looks more like the driver/daemon isn't running and providing the socket that irsend connects to


In a way, but probably not quite the way you're thinking. It's not a script, it's a binary executable, i.e. machine code.

So.... any suggestions for how to fix it?

Question: Would this error [read above] be the error I would get if I had put in the wrong remote codes in irblasterd.conf?

Hi,

One thing that needs to be done is make your comm port of choice get dumb. There is a setserial command that basically disables the uart so the port can be accessed, i suspect, directly.

It goes something like this: setserial /dev/ttyS0 uart=none but check for the exact syntax. I put mine command entry at bottom of the /etc/init.d/bootmisc.sh

I don't have access to that box right now that I have it on so this is only an awareness post.

Well I ran



And it appeared to go through, then I checked it and got:



I tried it multiple times always with the same result.

Also, I reread http://www.knoppmythwiki.org/index.php?page=PVR150withSetTopBox and decided to double-check some of the first steps I was told to skip, and I find that my /etc/lirc/hardware.conf and /etc/lirc/lirc-modules-source.conf are entirely unconfigured. Should I be concerned about this? Or are these only configured in order to use an IR Receiver?

Hi,

Do some searching for post by Greg Frost as he has some good stuff.

if you do setserial /dev/ttyS0 I believe if the comm port is set correctly if it reports the uart as none. I am pretty sure that was for the red eye out . I just remember it was a factor with the serial ir .

Mike

I'm still very very stuck and starting to get very frustrated with this whole IR blaster thing.

So those files I mentioned control an IR Receiver. If I don't have one, will an IR Blaster work if they're still blank?

And if that command I mentioned doesn't "dumb" the comm socket, I would have no idea what would.

I'm desperate for help.

I've got a VERY similar setup. Greg Frost has advised me a little on this. I think my serial IRBLASTER is sending data when the change_channel.sh script runs (I see the IR LED blinking when I watch it from a digital video camera), but my satellite receiver isn't changing channels, so I'm not sure what is wrong.

You might try removing the '--device=/dev/irblasterd' from your channel_change.sh
script and modifying /var/lib/setserial/autoserial.conf as in this post

You might give that a try and see if you can get it to work for you.
There is a MythTV wiki that is really good.
Good LUck
