iOS Background ranging

iOS Background ranging

[pipozoft]

I've been experiencing the same issue, it will be nice if the app monitors the region in background, that way we can notify users when entering/exiting a region.

It is possible to do this with the plug-in. The one catch I seem to be having is that if the app is close for a significant period of time, it no longer monitors the regions that I specified. However, if the app is recently closed, or is in the background, it can monitor regions just fine by following the example in the documentation.

@sunsus To my knowledge, iOS stops ranging when the app is in the background, so the plugin has no way to make that possible. Well, maybe with Core Bluetooth it is possible to emulate similar behaviour, but that's out of my reach at the moment.

@pipozoft @morrissinger You guys are talking about monitoring, not ranging, right?

@petermetz yes monitoring, I'm trying to make it alert me with a local notification (using other plugin) when I enter and exits the region. For that the app needs to be in the background and continue monitoring.

Also I don't know if it's my beacon but even if my phone it's next to it, it keeps saying that it's outside the region. Al thought ranging says the beacon is right next to me.

@pipozoft Can you try enabling debug notifications please?

It's not very well documented (yet) but the plugin supports posting local notifications for debug purposes, out of the box from the native layer, whenever an enter/exit event is received from iOS.

This means if you call locationManager.enableDebugNotifications() before you start monitoring, you should see local notifications about the exit/entry events. If those don't pop up, then it means the native layer never received the events you are waiting for, and that's why the plugin doesn't know anything about them either.

If the notifications pop up, but your DOM delegate methods are not fired, that usually means a bug in the plugin's transport layer.

I hope this helps.

@petermetz -- I am talking about monitoring. Everything that I read suggests that ranging in background or on a closed app state is completely impossible, with the exception of one article I read from Apple (which I will link if I can find it again) that says it is "generally" not possible.
