How do you start the disconnect call? Your app is suspended in background operation, thus your request will be fired only if the periheral starts some interaction or you bring the app back to foreground.

I remember once I tried and it seemed like my NSTimer was not suspended if I added the bluetoothPeripheral background. (I'm not sure if I did not wait enough for it to be suspended too.) But the main thread is suspended for sure, so scheduling the disconnect with a dispatch_after() or something similar will not be activated until the app comes back to foreground.
