Remote help!

Hello, LIRC folks...

I have a AT&T U-verse box (Cisco ISB7500) that came with a remote that
looks an aweful lot like an MCE remote.

I've tried all the MCE configs, tried doing an irrecord (which results
in config files with codes repeated multiple times for different
buttons - like 2 and 3 will both be 0x71 or 0x72).  I've tried the
irrecord at least a dozen times and it's a hit or miss thing.  I have
not tried raw mode, though (I read somewhere that was bad).

I'm at a loss.  I took the remote apart and the only thing I can
figure out is the board was probably printed by Hung Hing electronics
and it uses a DC6688F chip from Dragon Chips as the main (only) IC on
the board.

I've got a Hauppage remote that works perfectly, but what I'm trying
to do is at least get the numbers and the OK button off the MCE-like
remote to be able to blast it to the Uverse box for channel changing.

I'm using LIRC 0.9.0 (mythbuntu distribution) with an IguanaWorks transceiver.

Anybody have any ideas?

AH!  Genius!  Thank you!!!

Consider sending that to the LIRC guys so they put it in their
database.  You're a lifesaver!!

Re: Remote help!

What is the version of your kernel?  There was a timeout error that affected
mceusb version 1 devices.  Actually I'm not sure that got fixed.

Try looking at the waveforms using xmode2.  With the too-short timeout, I
tended to see visibly obvious errors for some of my remote controls, while
others mostly worked fine, or at least had a sufficiently low probability of
hitting a timeout, that they seemed to work most of the time.

3.0.0-21-generic-pae

Xmode2 requires a character device (/dev/lirc) to work.  IguanaIR,
unfortunately, only provides a socket.  I'll have to dig around.  With
the remote profile that John provided, though, it works just fine.
I've got other fish to fry at this point.

Hi Eric,

RAW mode is fine to try, if all else fails.

You are seeing the same symptoms I saw with my PayTV remote, it may be the protocol they are utilising isn't
irrecord friendly.

irsend - lirc 0.9.0 - RCMM

hi
I has the same issue with my remote that uses the RCMM protocol, and using lirc 0.9.0.
Would always get irsend:timeout error , even though it worked flawlessly in previous versions of lirc.
The solution for me was to modify the gap in my lircd.conf file.
Mine was about 100000, i kept reducing it down , I now have it at 18000 and and my transmitter works flawlessly when blasting, with no irsend:timeout errors.
Hope this helps
John
