I was about to ask a related question for android 4.3. According to Estimote:
On Android 5.0 the app still has to be running in the background, but the background scanning was redesigned to greatly improve power efficiency.
Do I correctly understand that this means that when the android screen times out, or the app goes to sleep, a message from the arduino can wake up the app? the application I'm making is for electric touring bikes. obviously it would suck the battery down to keep the screen on for long periods. it will be necessary to wake up the droid when some important event or alert happens.
I have one device that is android 4.3 and another that is android 5. I did not let one upgrade because the RedBear demo (I believe) android app does not support 5.0.
in the case of evothings, does it matter or is one better supported?
