I'm making slow progress on this one.... I added the do-nothing 'Game' command before and after all instances of all Advent TV power commands in all of my macros and LKP keymoves, and it has definitely helped in masking the effects of the toggle bit messing with my macros. Also had a reoccurance of the lack of response to the sequence dev_tv;0;3 which I remedied by changing it to dev_tv;shift-0;shift-3, which is odd since I have nothing out of the ordinary mapped to those keys. But it works now.

Still needs more work to get the Bose macros back to a reasonably reliable configuration, but I'm getting there. It just seems like this is a pretty hokey way to get there - and if there were any way to get rid of or disable that toggle bit stuff, it would make everything a lot easier! Programming my 3-device Pioneer codes way back when was a walk in the park compared to this!

Thx,
Tbone

Thanks for the reply, John - I was afraid that would be the answer... But there has to be something going on there, as the effect of adding those 'extra' commands is quite pronounced on the response of the Bose.

Hey, thanks for the replies, guys. Lots of good info here to be digested. I will definitely be checking out the Barry Gordon document to see what I can learn from that.

Not to continue being a pain here, but I have one more question - how difficult would it be to add a command or series of commands to the bose protocol to simply load a 1 or 0 (whichever one we figure out via experimentation is what the bose wants to see) into this R00 register for every bose command, so that it would always be in the correct state? Seems to me that it could easily be done, but the last real programming course I took was back in the 80's or so, so what do I know....

Thanks again,
Tbone

We don't know for certain that it wants the toggle to always be in a certain state. The main purpose of toggle bits is to differentiate between when a button is held down, versus when a button is being repeatedly pressed. For example, if you were to hold down a certain button, the toggle bit would remain in the same sate for all the repetitions. But, if you were to keep pressing the same button over and over, the toggle would keep toggling.

It seems that the Bose requires the toggle to be on (or off) for the first press of every button.

Have you tried learning the same button multiple times to see how the toggle changes. Make sure that you press some other Bose button first, then start learning the button in question. This is to make sure that the first learn you do of the button is the first time the button is pressed, this will tell us whether the first state is actually ON or OFF.

Just to clarify, the learns in my previous post were from the original bose remote, and then I compared the signals to those described by PB. Sorry for any confusion........

I never saw anything in this thread to make me believe the toggle bit is a factor in the behavior of the Bose. There are many reasons to be convinced that it isn't.

From the posted file, I couldn't make a good guess why the extra VCR command in a macro would affect subsequent Bose commands. My usual guess in such situations is that the symptom report in wrong or misunderstood. A more controlled test would probably give a different result.

This thread has had far too much discussion of the internal processing of the toggle bit, and R00, and posible kludges based on an usupported guess at the underlying issue, and too little systematic investigation of the actual symptom.

I didn't and don't know the answer to this situation.

I didn't (and still don't) see enough information in this thread to comment usefully.

I thought the right answer would be evident from TB's IR file. But once I saw that file it didn't make the right answer evident to me. It did make the wrongness of the wrong answer more evident. I didn't find the relevent file from Greg either, so I didn't have actual access to the protocol any sooner than any other expert reading this thread.
