[FR] Cervantes: double click on home button

[Brnoch]

Device: bq Cervantes As the button located on the edge of the Cervantes is not easy to use (especially at night), it's somewhat difficult to put the reader in standby mode, and then to wake him up. Would it be possible to implement one functionality of the bq firmware : when the user double clicks on the home button, the reader goes to standby mode, and when he performs the same action while the reader is in standby mode, the reader wakes up?

Btw, there are many ways to enter standby besides using the button. It can be assigned to a gesture of your choice via Settings → Taps & gestures → Gesture manager, as well as via Hamburger/File → Exit → Sleep.

But can you wake it up with gesture? The edge button is pretty weak, so I'd also vote for double-click feature to suspend/wakeup

[Frenzie]

So you're saying the device doesn't wake up when you double tap that button?

[Brnoch]

Yes, nothing happens in this case

@avsej: feel free to implement it if you wish. I'm not interested myself. IMHO is not worth the hassle.

Generating multiple key events based on different press/release patterns is not difficult. You can rename the "Home" action to something like "MultiActionButton" and add a new handler on input.lua. This way you can delay actions a few milliseconds (to wait for a given pattern) without messing with delays for other actions.

So you're saying the device doesn't wake up when you double tap that button?

Nope, but I never tried to program it otherwise, so I dunno if this is actually feasible. https://github.com/bq/cervantes/blob/master/QBookApp/src/PowerManager.cpp could be useful to understand the way BQ app handles power states :+1:

Edit: actually https://github.com/bq/cervantes/blob/master/QBookApp/src/QBookApp.cpp#L2429-L2486 shows the behaviour.

@pazos Too bad you're not interested. Maybe it's because I use my cervantes 4 for a short time now, but I always struggle to find the edge button with my finger.
