Hi Nick,

if your app is killed by the user, then you are done. There is nothing to prevent or act upon it.

If your app is killed by the system, then state restoration should do its job, given you set up the connectPeripheral:options: options correctly. Please look up the related documentation and tons of StackOverflow Qs.

To keep your app connected, you should issue connectPeripheral with the same parameters as previously, as soon as you receive the disconnected callback.

Thanks,

Andras

Hi all, hoping someone can help with this.

I want my App to either be connected or attempting to connect to a known peripheral previously discovered or retrieved with -retrievePeripheralsWithIdentifiers or -retrieveConnectedPeripheralsWithServices. When the peripheral disconnects, re-connection should be attempted. In this way, the App receives notifications from the peripheral and presents local push notifications. This works fine when the App is in the foreground or in the background while still running.

In the background, if the App is killed for whatever reason (user closes, memory low) then the system disconnects the peripheral, but the App does not get notified of disconnection, so cannot reconnect automatically to continue receiving notifications. How can I attempt reconnection when the App is quit?

Nick
