公共方法(Public methods)

onCharacteristicChanged

Added in API level 18 
void onCharacteristicChanged (BluetoothGatt gatt, 
                BluetoothGattCharacteristic characteristic)

由于远程特征通知而触发的回叫。

参数(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.

onCharacteristicRead

Added in API level 18 
void onCharacteristicRead (BluetoothGatt gatt, 
                BluetoothGattCharacteristic characteristic, 
                int status)

回叫报告特征读取操作的结果。

参数(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.

onCharacteristicWrite

Added in API level 18 
void onCharacteristicWrite (BluetoothGatt gatt, 
                BluetoothGattCharacteristic characteristic, 
                int status)

表示特征写入操作结果的回调。

如果在进行可靠的写入事务时调用此回调，则该特性的值表示远程设备报告的值。 应用程序应将此值与要写入的期望值进行比较。 如果值不匹配，则应用程序必须中止可靠的写入事务。

参数(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.

onConnectionStateChange

Added in API level 18 
void onConnectionStateChange (BluetoothGatt gatt, 
                int status, 
                int newState)

回叫指示GATT客户端何时连接到远程GATT服务器/从远程GATT服务器断开连接。

参数(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

onDescriptorRead

Added in API level 18 
void onDescriptorRead (BluetoothGatt gatt, 
                BluetoothGattDescriptor descriptor, 
                int status)

回调报告描述符读取操作的结果。

参数(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

onDescriptorWrite

Added in API level 18 
void onDescriptorWrite (BluetoothGatt gatt, 
                BluetoothGattDescriptor descriptor, 
                int status)

回调，指示描述符写入操作的结果。

参数(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.

onMtuChanged

Added in API level 21 
void onMtuChanged (BluetoothGatt gatt, 
                int mtu, 
                int status)

指示给定设备连接的MTU的回叫已更改。 此回调是为响应requestMtu(int)函数或响应连接事件而触发的。

参数(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

onReadRemoteRssi

Added in API level 18 
void onReadRemoteRssi (BluetoothGatt gatt, 
                int rssi, 
                int status)

回拨报告远程设备连接的RSSI。 这个回调是为了响应readRemoteRssi()函数而触发的。

参数(Parameters)
gatt BluetoothGatt: GATT client invoked readRemoteRssi()
rssi int: The RSSI value for the remote device
status int: GATT_SUCCESS if the RSSI was read successfully

onReliableWriteCompleted

Added in API level 18 
void onReliableWriteCompleted (BluetoothGatt gatt, 
                int status)

当可靠的写入事务完成时调用回调。

参数(Parameters)
gatt BluetoothGatt: GATT client invoked executeReliableWrite()
status int: GATT_SUCCESS if the reliable write transaction was executed successfully

onServicesDiscovered

Added in API level 18 
void onServicesDiscovered (BluetoothGatt gatt, 
                int status)

当远程设备的远程服务，特性和描述符列表已更新时（即发现新服务），调用回调。

参数(Parameters)
gatt BluetoothGatt: GATT client invoked discoverServices()
status int: GATT_SUCCESS if the remote device has been explored successfully.
