Turn On and Off the Fenix 3 HR Backlight

Former Member over 8 years ago

I have tried the following ...

System.println (evt.getKey()); and it returns nothing in the Simulator in SDK 2.2.1 and the INPUT sample is the same way, it does not respond to anything.
All the other buttons are fine .. just not the 'LIGHT' button.

I am at a loss ... I just want to turn the back light on and off with that press of the light button.

I would imagine that is the purpose of that button but I do not own a Fenix.

I don't believe you can't get KEY_LIGHT in a delegate, and the input sample in the sim kind of proves that.

But you may not need it for what you are trying to do. It's handled by the FW. Pressing the light button turns on the backlight, and after a timeout, it turns off.

If you want to keep it on, you'll have to find a different way to toggle it.

Ok .. then I will just ignore it then. It is just cause it is not like the VAHR that I am used to.

Another thing that I have noticed when I've done testing on the fenix 3 is that it strictly adheres to system settings when it's called. For example, if the systems settings are set so that the back light is on when a key is pressed, then the toggle to turn on does nothing. Toggling to turn it off will turn it off, but then it immediately turns back on because a key has been pressed. I don't think that is related to exactly to what you have going on, but thought I might chime in.

Thanks Coleman

My issue was well .. a lack of knowledge about the Fenix models and a dedicated light button. I am used to the Vivoactive HR with no such button and have done things like turn on / off the light with a tap. That is what I find most convenient in use. So it all works.
