					 *  If we discover services right after connecting, the onServicesDiscovered callback will be called immediately, before receiving the indication and the following 
					 *  service discovery and we may end up with old, application's services instead.
					 *  
					 *  This is to support the buttonless switch from application to bootloader mode where the DFU bootloader notifies the master about service change.
					 *  Tested on Nexus 4 (Android 4.4.4 and 5), Nexus 5 (Android 5), Samsung Note 2 (Android 4.4.2). The time after connection to end of service discovery is about 1.6s 
					 *  on Samsung Note 2.
