In the mean time I discovered one button on the toy remote (and as yet none on the phone app) that will send a user button press. It is a play/pause button that sends both the press and release messages on a single depression of the button. There is no distinction between pause and play.mark wrote:So, since I don't have a lab tv that works I'm going to get a new one instead of pursuing access to other tv's.
Since I'm not ready to purchase the new tv, I'm going to experiment with what is about the simplest input signal possible. It is a lot like inserting/removing the sd card which I use to reset config.txt without resorting to windows or linux.
The toy remote has an input selection button that on the first press displays the current input name and subsequent presses indicate the next input. If pressed enough times to get back to the current input, there won't be any change. If left on a new input for a second or so, then that new input will be activated. I'll experiment with that model.
