Re: Resetting CentralManager to re-detect previously detected devices

Unfortunately that flag is ignored in background. This behavior has not changed in iOS6. I haven't seen any "regular" way to implement what you would like. However, there is a theoretical solution. I have not tried it yet but I suppose it should work. When you receive the didDiscoverCallback, the app gets about 10 seconds to run. During this, you may restart the scanning by stopping it first and then starting again. The question is whether restarting the scan clears out the cache while the app is backgrounded.
