void onCharacteristicChanged (BluetoothGatt gatt, BluetoothGattCharacteristic characteristic)
Callback triggered as a result of a remote characteristic notification.
Parameters | |
---|---|
gatt |
BluetoothGatt :
GATT client the characteristic is associated with |
characteristic |
BluetoothGattCharacteristic :
Characteristic that has been updated as a result
of a remote notification event.
|
void onCharacteristicRead (BluetoothGatt gatt, BluetoothGattCharacteristic characteristic, int status)
Callback reporting the result of a characteristic read operation.
Parameters | |
---|---|
gatt |
BluetoothGatt :
GATT client invoked readCharacteristic(BluetoothGattCharacteristic) |
characteristic |
BluetoothGattCharacteristic :
Characteristic that was read from the associated
remote device. |
status |
int :
GATT_SUCCESS if the read operation
was completed successfully.
|
void onCharacteristicWrite (BluetoothGatt gatt, BluetoothGattCharacteristic characteristic, int status)
Callback indicating the result of a characteristic write operation.
If this callback is invoked while a reliable write transaction is in progress, the value of the characteristic represents the value reported by the remote device. An application should compare this value to the desired value to be written. If the values don't match, the application must abort the reliable write transaction.
Parameters | |
---|---|
gatt |
BluetoothGatt :
GATT client invoked writeCharacteristic(BluetoothGattCharacteristic) |
characteristic |
BluetoothGattCharacteristic :
Characteristic that was written to the associated
remote device. |
status |
int :
The result of the write operation
GATT_SUCCESS if the operation succeeds.
|
void onConnectionStateChange (BluetoothGatt gatt, int status, int newState)
Callback indicating when GATT client has connected/disconnected to/from a remote GATT server.
Parameters | |
---|---|
gatt |
BluetoothGatt :
GATT client |
status |
int :
Status of the connect or disconnect operation.
GATT_SUCCESS if the operation succeeds. |
newState |
int :
Returns the new connection state. Can be one of
STATE_DISCONNECTED or
STATE_CONNECTED
|
void onDescriptorRead (BluetoothGatt gatt, BluetoothGattDescriptor descriptor, int status)
Callback reporting the result of a descriptor read operation.
Parameters | |
---|---|
gatt |
BluetoothGatt :
GATT client invoked readDescriptor(BluetoothGattDescriptor) |
descriptor |
BluetoothGattDescriptor :
Descriptor that was read from the associated
remote device. |
status |
int :
GATT_SUCCESS if the read operation
was completed successfully
|
void onDescriptorWrite (BluetoothGatt gatt, BluetoothGattDescriptor descriptor, int status)
Callback indicating the result of a descriptor write operation.
Parameters | |
---|---|
gatt |
BluetoothGatt :
GATT client invoked writeDescriptor(BluetoothGattDescriptor) |
descriptor |
BluetoothGattDescriptor :
Descriptor that was writte to the associated
remote device. |
status |
int :
The result of the write operation
GATT_SUCCESS if the operation succeeds.
|
void onMtuChanged (BluetoothGatt gatt, int mtu, int status)
Callback indicating the MTU for a given device connection has changed.
This callback is triggered in response to the
requestMtu(int)
function, or in response to a connection
event.
Parameters | |
---|---|
gatt |
BluetoothGatt :
GATT client invoked requestMtu(int) |
mtu |
int :
The new MTU size |
status |
int :
GATT_SUCCESS if the MTU has been changed successfully
|
void onReadRemoteRssi (BluetoothGatt gatt, int rssi, int status)
Callback reporting the RSSI for a remote device connection.
This callback is triggered in response to the
readRemoteRssi()
function.
Parameters | |
---|---|
gatt |
BluetoothGatt :
GATT client invoked readRemoteRssi() |

status |
int :
GATT_SUCCESS if the RSSI was read successfully
|
void onReliableWriteCompleted (BluetoothGatt gatt, int status)
Callback invoked when a reliable write transaction has been completed.
Parameters | |
---|---|

GATT client invoked executeReliableWrite() |
status |
int :
GATT_SUCCESS if the reliable write
transaction was executed successfully
|
void onServicesDiscovered (BluetoothGatt gatt, int status)
Callback invoked when the list of remote services, characteristics and descriptors for the remote device have been updated, ie new services have been discovered.
Parameters | |
