Light sensor start fail
-
I am using the light sensor(QLightSensor) to read the light data. It works well on the simulator.
But failed on the real device(C7)I debug, and find out that the sensor.start() return false.
why??
-
The code is rather simple:
@
QLightSensor* m_LightSensor;
QLightReading* m_LuxReading;m_LightSensor = new QLightSensor(this);
bool started = m_LightSensor->start();if(!started)
{
return;
}
m_LuxReading = m_LightSensor->reading();
@
then it always start fail.
The capability is added, NetworkServices ReadDeviceData WriteDeviceData ReadUserData WriteUserData
I have add the heap : TARGET.EPOCHEAPSIZE = 0x020000 0x1000000 -
I tested with QAmbientLightSensor, this works well. Then I change to QLightSensor, it failed. WHY??
-
I use QList<QByteArray> sensorArray = QSensor::sensorTypes();
and it seems that the lightsensor is not included in the symbian system.
