Resolve #142
Use of this method is discussed here: http://stackoverflow.com/questions/22596951/how-to-programmatically-force-bluetooth-low-energy-service-discovery-on-android
Basically, some phones cache the list of services and characteristics between connections. So if the device has changed it's services or characteristics since you last connected, you can have fatal errors. The refresh() method will clear the phone's cached list.
Nordic have an implementation here : https://github.com/NordicSemiconductor/Android-BLE-Library/blob/dc46cd3d72d6d5f643c60cdeecc065942143336c/ble/src/main/java/no/nordicsemi/android/ble/BleManagerHandler.java#L1594
