LCD Timeout and screen lock timeout are the same?

There is no option in the UI at the moment, but you can do it with code. You want to use Bangle.setOptions(). You pass in an object with the properties that you want to change. The relevant properties are:

• lockTimeout: how many milliseconds before the screen locks (set this to 60000 for 60 seconds)
  
• backlightTimeout: how many milliseconds before the screen's backlight turns off (set this to 5000 for 5 seconds)
  
  

Don't confuse backlightTimeout with lcdPowerTimeout: lcdPowerTimeout turns off the entire screen. You want to leave that at zero so the screen stays on.

TLDR:

Bangle.setOptions({
  lockTimeout: 60000,
  backlightTimeout: 5000
});
