Constant Value: 0 (0x00000000)
int SERVICE_TYPE_SECONDARY
Secondary service (included by primary services)
Constant Value: 1 (0x00000001)
List<BluetoothGattCharacteristic> mCharacteristics

BluetoothGattService (UUID uuid, int serviceType)
Create a new BluetoothGattService.
Requires BLUETOOTH
permission.
Parameters | |
---|---|
uuid |
UUID : The UUID for this service |
serviceType |
int : The type of this service, SERVICE_TYPE_PRIMARY or SERVICE_TYPE_SECONDARY |
boolean addCharacteristic (BluetoothGattCharacteristic characteristic)
Add a characteristic to this service.
Requires BLUETOOTH
permission.
Parameters | |
---|---|
characteristic |
BluetoothGattCharacteristic : The characteristics to be added |
Returns | |
---|---|
boolean |
true, if the characteristic was added to the service |
boolean addService (BluetoothGattService service)
Add an included service to this service.
Requires BLUETOOTH
permission.
Parameters | |
---|---|
service |
BluetoothGattService : The service to be added |
Returns | |
---|---|
boolean |
true, if the included service was added to the service |
BluetoothGattCharacteristic getCharacteristic (UUID uuid)
Returns a characteristic with a given UUID out of the list of characteristics offered by this service.
This is a convenience function to allow access to a given characteristic without enumerating over the list returned by getCharacteristics()
manually.
If a remote service offers multiple characteristics with the same UUID, the first instance of a characteristic with the given UUID is returned.
Parameters | |
---|---|
uuid |
UUID
|
Returns | |
---|---|
BluetoothGattCharacteristic |
GATT characteristic object or null if no characteristic with the given UUID was found. |
List<BluetoothGattCharacteristic> getCharacteristics ()
Returns a list of characteristics included in this service.
Returns | |
---|---|
List<BluetoothGattCharacteristic> |
Characteristics included in this service |
List<BluetoothGattService> getIncludedServices ()
Get the list of included GATT services for this service.
Returns | |
---|---|
List<BluetoothGattService> |
List of included services or empty list if no included services were discovered. |
int getInstanceId ()
Returns the instance ID for this service
If a remote device offers multiple services with the same UUID (ex. multiple battery services for different batteries), the instance ID is used to distuinguish services.
Returns | |
---|---|
int |
Instance ID of this service |
int getType ()
Get the type of this service (primary/secondary)
Returns | |
---|---|
int |
UUID getUuid ()
Returns the UUID of this service
Returns | |
---|---|
UUID |
UUID of this service |
void writeToParcel (Parcel out, int flags)
Flatten this object in to a Parcel.
Parameters | |
---|---|
out |
Parcel : The Parcel in which the object should be written. |
flags |
int : Additional flags about how the object should be written. May be 0 or PARCELABLE_WRITE_RETURN_VALUE . |
