Remarks

Setting the Characteristic property to the Id of a discovered characteristic allows you to inspect the descriptors which have been discovered for it using the Descriptor* properties.

Characteristic can either be set to the Id of a characteristic which has been discovered for the service currently selected by Service, or to empty string.

This property is automatically set when you call the Select method; and it is reset to empty string when you set Service.

This property is not available at design time.
