title: Continuous scanning for iOS CoreBluetooth Central Manager?
body: <p>The Low Energy Bluetooth spec does not say much about whether peripherals can connect to more than one central at a time, but my experience testing tells me that they cannot.  </p>
  
  <p>Because my application requires a non-possessive relationship with peripherals (i.e. no connections, which would block others), and needs to constantly update their RSSI values, I am seeking a way to continuously scan for peripherals and capture their RSSI values.</p>
  
  <p>The scanForPeripheralsWithServices method appears to scan for a certain interval and then stops.   I believe my best bet is to scan for 3 seconds at a time, stopScan, wait (several seconds) and then reinitiate a scan.   Repeat.  </p>
  
  <p>Can anyone point to a better way of doing it?   For example, configuring a peripheral to connect to more than one Central?</p>
