Sleep key is repeated after the computer wakes

Help and Getting Started
1

Hi,

I have configured fun+any to be the System_sleep key using chrysalis. (see How to add sleep and power keys?)

It indeed put the computer to sleep, but when I wake it using the computer’s power button, it goes back to sleep just after waking up. To prevent this I need to unplug my Model 100, wake the computer, then plug the keyboard again.

I conclude that somehow, the model 100 keeps sending the sleep signal instead of sending it only once.
any idea why it happens and how to solve it ?

  1. Which OS are you using?
  2. Does the same thing happen if you use the Consumer Control Sleep key?

I am using Artix (Arch fork without systemd)
Consumer_Sleep seems not to have this issue. I am not sure what is the difference between them.

Here’s what’s probably happening. The System Control USB HID protocol sends only a single “keycode” at a time. Basically, the report is either “off” or it has the value of whatever the latest key pressed is. The keyboard sends a report whenever a System Control key toggles on or off (though not necessarily if there’s rollover from one System Control key to another). What I think is going on is that the system is responding to the System_Sleep key’s “on” report, but then system goes to sleep before it gets the “off” report, and when it wakes up, it still hasn’t received it, so it immediately goes to sleep again. I guess there’s a problem in the HID code somewhere, possibly even in the Arduino library. Or maybe it’s a bug in the OS.

The Consumer Control HID protocol is more full-featured (up to four keys active at a time), and is handled better by the OS.

I’ll take a look at the System Control code in KeyboardioHID, but I honestly don’t expect to find a solution there.

OK, it makes sense.
Anyway, I now use Consumer_Sleep and it works perfectly fine for me. (At least on Artix, I haven’t tried on Windows yet.)

So, thanks again !
