Updating the Temperature Characteristic
In the previous assignment, the custom Temperature characteristic is defined with a notify attribute. This
type of attribute requires notification to be sent to central when a new characteristic value is available.
The update of any “notify” characteristic value is based on following interaction between the Host MCU
and the ATBTLC1000.
