Page Load Repeating Action

[d_hero]

If I have a repeating action running on page load that repeats every 0.5 seconds, querying the output of something, will that significantly drain the battery compared to not having it?

To answer my own question, it does seem that when I remove the page load action the battery life is much better. If only IP devices could push messages to Demopad rather than demopad having to query for something.

I want to display the output of my AV receiver on the demopad screen, so showing the input and volume and surround mode etc. I want this to update in almost realtime because my AVR will be hidden away. Currently to do this I send the Onkyo query commands every 0.5 or 1 second with regex used to extract the required info. I take it there is no other way to do this so that I dont have to have a constantly running query?

The Onkyo and most other receivers send out a message when anything changes, so why do you need to Query??
If you have feedbacks set on Demopad they will receive the messages and update.

Oh ok, I didnt realise that. How does demopad know to receive that message though? Is it a broadcast message that the receiver sends out?

If you tick the box 'maintain active connection' in the 2-way settings, then the app establishes a connection & permanently listens for data, while the app is running.

yeah i feel stupid now, i spent ages trying to get the queries working and i didnt need to at all! works perfectly without and saves battery, but you all knew that!
