This function will return details about the last temperature notification event received.
To get the ID of the sender related to the event, please call rfbcWaitEvent before this function.
Input:
None.
Output:
temperature : INT
The measured temperature in 1/10 deg. Celsius.
humidity : INT
Humidity reported by remote device if supported.
Note: not all temperature sensors report humidity, and in these cases, it will be -9999.
Returns: INT
