Hi,
As i got no helping responses on how generate an event from a plugin and
how to change the .ResourceFailed flag, i retry again on this
mailing-list. Sorry if that disturb you.
I just tried to modify a get_sensor_reading() function to try to emit an
event when the sensor value raise above a specific threshold. In that
case, i try additionaly to change the value of the ResourceFailed flag
to FALSE. For the moment, without any success.
Thanks in advance if you have any clue about this specific problem.
The plugin i have modified is the simulator plugin.
