Hi Michael,
I checked what you said.
I found that:
1. It's meaningless to read control_fd[READ]. You did not
use the character you read from control channel anywhere. So I commented it.
2. The activating/deactivating the sensors is controlled by
System automatically. We need not use control channel to activate the
sensors. When we open an application which use the sensors service, the
system invokes the function control_activate to activate the sensors. After
you kill the process of the application, the system automatically invokes
the same function control_activate to deactivate the sensors.

This is what I rembember:
- the sensor_poll is called only when the sensor is activate
- the control channel is used to deactivate/activate sensor
The EWOULDBLOCK is correct when you are on select and waiting for an event
but you want to deactivate sensor. So the select pass and the system return
EWOULDBLOCK. The sensor is deactivated and I think that the system does't
call
again the sensor_poll.
Can you check this?
