* Our tests has shown that 600 ms is enough(*). It is important to call it AFTER receiving the SC indication, but not necessarily
* after Android finishes the internal service discovery.

* NOTE: This applies only for bonded devices with Service Changed characteristic, but to be sure we will postpone
* service discovery for all devices.

* (*) - While testing on Nexus 4 with Android 5.0.1 it appeared that 600 ms may be not enough.
* The service discovery initiated by the system was still in progress while gatt.serviceDiscovery() below
* was called and (due to a bug on older Android versions, where there can be only one callback registered)
* the onServicesDiscovered(...) callback has never been called.
