Mike, Robert -
Thanks for your wealth of insight on this. I'm starting to come up to speed,
I think.
So, the RCX is acknowledging the IR tower command string, based on receipt of
a EOS of some sort, perhaps, and OmniRemote can't process that ACK? I'll
re-read your posts again, and check out IrDA protocol sites to get a handle on
this. Or, maybe LEGO just uses it's own protocol that OmniRemote can't
100% emunlate through a training session. I think you've both discussed the
need for low-level IR command processing on the Pilot - sorry - old trade
name, I know, but I've had one since their initial retail release and I can't
give up old ways.
Thanks again, and I'm off to tinker a bit more...
...by the way, my goal is a remote controlled LEGO train layout for some
upcoming model train shows I'll be attending. It helps to promote LEGO in any
cool way you can think of. While lots of people comment to me "I didn't know
LEGO made trains" I want to go beyond that and have them say "I didn't know
LEGO made trains - and you can control them remotely with a Pilot!"

| Ed, yes the RCX is acknowledging most commands. It does not do this with the commands used in LRemote ((URL) -- I'm stuck on the old name too, for the same reason). The motor commands used in LRemote are repeating commands. As long as you hold down (...) (25 years ago, 12-Dec-99, to lugnet.robotics.palm)

| Ed, LEGO does not use IrDA protocol but this is not the problem with OmniRemote. OmniRemote simply records any IR it detects at training and transmits a copy of the signals no matter what format they are in. I believe the two main problems with (...)
