I'm developing an app using CoreBluetooth and I need to be notified if the bluetooth connection is lost. I establish connection with many BLE devices, put the app into background mode and wait for disconnect notification. The problem is I get didDisconnect method is invoked only if I push the off button on my BLE device but not when I get out of range. Do you have any idea why this could happen?

Thanks in advance for your reply.

Devices don't disconnect automatically when they get away from each other. You have to do that by yourself.

  • How app should know that Device is not in range now, or powered off ? (Consider that app is in foreground only) – iDevAmit Nov 07 '16 at 09:20
