Timer in the background

Former Member over 5 years ago

Hi Everyone,

I was trying to use a timer in the background, but I kept getting the following error:

Error: Permission Required

Details: Module 'Toybox.Timer' not available to 'Background'

When I checked the API documentation, it says that Timer allows background services, but in my application I am getting an error. Is there any reason for why this might be happening?

Okay, thank you

Something I tried years back was to use

Sensor.enableSensorEvents(method(:sensorEvents));

and sensorEvents should be called about every second, so you can do things there. I've never used it in a production app and I'm not sure it will still work..

The scripts that are generating the documentation appear to have a bug that causes the App Types listing to be incorrect.

The Timer module is available to Watch App, Widget, Audio Content Provider, and Watch Face (only at certain times) app types.

Also in glance view, as that'd being separately listed in other things.
