I have finally bought a Harmony 300 but I can't get it to work smoothly with Flirc.
With my other remote from a Hauppauge DVB tuner card, I have to program
twice each button, but afterwards it is silky smooth.
With the Harmony 300, OTOH, using the SAMSUNG LN46C650L1F profile, since
my TV is a Panasonic, there is too much delay between key presses. Reducing
Flirc's interkey_delay helps a little bit but not enough.
Using a Sony KDL-55HX855 profile the behavior is slightly different. The delay
between key presses is shorter, smoother, but there is another noticeable delay
before every key press. The result is that you notice a delay between the instant you
press a button and the instant the action is executed on screen.
Since the Hauppauge remote (which uses the RC5 protocol), after programming
each key twice, is silky smooth, I tried using its profile on the Harmony. I used
the IR receiver on the bottom of the Harmony to copy the IR codes of the Hauppauge
remote.
Then I configured Flirc with this new profile, also programming each key twice, but
there's still a noticeable delay before each key press.
I have also tried playing with Flirc's sensitivity and interkey_delay options but there
was not improvement.
I wonder if there is any way to get the same silky smooth response I get with the
Hauppauge remote (with RC5 protocol), after programming twice each button,
with the Harmony 300?
Otherwise it will be another botched purchase.
