Note
This function allows setting or resetting a trigger value which in turn triggers execution of
code within the reader service (e.g. triggering an RFID source to read tags).
Being able to set the state of a trigger to ON or OFF allows arbitrary behavior of the different
keys depending on their configuration. A key may work only as long as it is pressed or as an
on/off switch.
Limitations
RF-MANAGER mode only.
Successfully activating a trigger depends on a valid configuration being available. Such a
configuration is normally set by a connected RF-MANAGER. If no valid trigger configuration
for a given trigger type exists, an error is returned.
Version information
Supported in RFID Reader Interface: since V1.1
