* Workaround Android when connecting to non-existing/turned off deviceAlex Blasche2014-11-231-1/+22
| | | | | | | | | | | | | | In such cases a disconnect() call never receives a system callback that BluetoothGatt is disconnected. Similarly when the timeout hits the platform sends an unknown error code 133 and again doesn't send a disconnected status. This patch works around both issues by preempting the platform behavior. It seems that subsequent connect attempts are not harmed by this.

* Fix wrong error signal emision on writeCharacteristic() on AndroidAlex Blasche2014-11-141-2/+1
| | | | | | | | | | | There is no need to go around the event loop. Furthermore there is no signal "void error(QLEHandle)" in QLEService. The signal is void error(QLEService::ServiceError) Change-Id: I53e9eb9b82cff38b15edab524329fa98206ab27b Reviewed-by: Timur Pocheptsov <Timur.Pocheptsov@digia.com> Reviewed-by: Alex Blasche <alexander.blasche@theqtcompany.com>

* Fix intermittent failure when mapping handles to servicesAlex Blasche2014-11-121-1/+7
| | | | | | | | | | | | | startHandle and endHandle were randomly initialized and thus QLowEnergyControllerPrivate::serviceForHandle(..) failed at the same rate. In addition this adds a few debug logs which turned out useful when debugging the above issue.

* Improve reliability of QLEController connect()/disconnect()/connect()Alex Blasche2014-11-121-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | Quick disconnecting and reconnecting caused some bugs and revealed some unreliabe API behavior on Android. The internal data structures were never cleaned up when disconnecting from the remote device. If multiple QLEService objects of the same QLEController instance requested a service discovery, every request but the first failed. This was fixed by queueing up the service discovery requests. Last but not least, reusing the same BluetoothGatt instance for the reconnect is very error prone. It may well be caused by Android API bugs. The reconnect would sometimes fail or toggle the connect/disconnect flag a couple of times which is not a problem for the Qt API itself but the stability of the related unit test (see tst_QLowEnergyController::tst_concurrentDiscovery()). Therefore we won't reuse the same BluetoothGatt instance but rather request a new one.
