This function will return details about the last remote control event received.
To get the ID of the sender related to the event, please call rfbcWaitEvent before this function.
Note: if configured to send an acknowledgment, then a switch on/off confirmation will be sent based on the button number ("off" for even numbers and "on" for odd numbers).
Input:
None.
Output:
button : SINT
The index of the button that is pressed. On some devices this may also be referred to as a channel number.
longPress : BOOL
TRUE
|
-
|
The button is pressed and held. The definition of a long press depends on the configuration of the sending remote control device.
