Parameters for the GATT Add Characteristic command.

Fields

service_handle: ServiceHandle

Handle of the service to which the characteristic has to be added

characteristic_uuid: Uuid

UUID of the characteristic

characteristic_value_len: usize

Maximum length of the characteristic value

characteristic_properties: CharacteristicProperty

Properties of the characteristic (defined in Volume 3, Part G, Section 3.3.3.1 of Bluetooth Specification 4.1)

security_permissions: CharacteristicPermission

Security requirements of the characteristic

gatt_event_mask: CharacteristicEvent

Which types of events will be generated when the attribute is accessed.

encryption_key_size: EncryptionKeySize

The minimum encryption key size requirement for this attribute.

is_variable: bool
