Public methods

onCharacteristicReadRequest

Added in API level 18 
void onCharacteristicReadRequest (BluetoothDevice device, 
                int requestId, 
                int offset, 
                BluetoothGattCharacteristic characteristic)

远程客户端已经请求读取本地特征。

应用程序必须致电 sendResponse(BluetoothDevice, int, int, int, byte[])才能完成请求。

Parameters
device BluetoothDevice: The remote device that has requested the read operation
requestId int: The Id of the request
offset int: Offset into the value of the characteristic
characteristic BluetoothGattCharacteristic: Characteristic to be read

onCharacteristicWriteRequest

Added in API level 18 
void onCharacteristicWriteRequest (BluetoothDevice device, 
                int requestId, 
                BluetoothGattCharacteristic characteristic, 
                boolean preparedWrite, 
                boolean responseNeeded, 
                int offset, 
                byte[] value)

远程客户端已请求写入本地特征。

应用程序必须调用 sendResponse(BluetoothDevice, int, int, int, byte[])来完成请求。

Parameters
device BluetoothDevice: The remote device that has requested the write operation
requestId int: The Id of the request
characteristic BluetoothGattCharacteristic: Characteristic to be written to.
preparedWrite boolean: true, if this write operation should be queued for later execution.
responseNeeded boolean: true, if the remote device requires a response
offset int: The offset given for the value
value byte: The value the client wants to assign to the characteristic

onConnectionStateChange

Added in API level 18 
void onConnectionStateChange (BluetoothDevice device, 
                int status, 
                int newState)

回叫指示何时远程设备已连接或断开连接。

Parameters
device BluetoothDevice: Remote device that has been connected or disconnected.
status int: Status of the connect or disconnect operation.
newState int: Returns the new connection state. Can be one of STATE_DISCONNECTED or STATE_CONNECTED

onDescriptorReadRequest

Added in API level 18 
void onDescriptorReadRequest (BluetoothDevice device, 
                int requestId, 
                int offset, 
                BluetoothGattDescriptor descriptor)

远程客户端请求读取本地描述符。

应用程序必须致电 sendResponse(BluetoothDevice, int, int, int, byte[])才能完成请求。

Parameters
device BluetoothDevice: The remote device that has requested the read operation
requestId int: The Id of the request
offset int: Offset into the value of the characteristic
descriptor BluetoothGattDescriptor: Descriptor to be read

onDescriptorWriteRequest

Added in API level 18 
void onDescriptorWriteRequest (BluetoothDevice device, 
                int requestId, 
                BluetoothGattDescriptor descriptor, 
                boolean preparedWrite, 
                boolean responseNeeded, 
                int offset, 
                byte[] value)

远程客户端已请求写入本地描述符。

应用程序必须致电 sendResponse(BluetoothDevice, int, int, int, byte[])才能完成请求。

Parameters
device BluetoothDevice: The remote device that has requested the write operation
requestId int: The Id of the request
descriptor BluetoothGattDescriptor: Descriptor to be written to.
preparedWrite boolean: true, if this write operation should be queued for later execution.
responseNeeded boolean: true, if the remote device requires a response
offset int: The offset given for the value
value byte: The value the client wants to assign to the descriptor

onExecuteWrite

Added in API level 18 
void onExecuteWrite (BluetoothDevice device, 
                int requestId, 
                boolean execute)

执行此设备的所有挂起写入操作。

应用程序必须致电 sendResponse(BluetoothDevice, int, int, int, byte[])才能完成请求。

Parameters
device BluetoothDevice: The remote device that has requested the write operations
requestId int: The Id of the request
execute boolean: Whether the pending writes should be executed (true) or cancelled (false)

onMtuChanged

Added in API level 22 
void onMtuChanged (BluetoothDevice device, 
                int mtu)

指示给定设备连接的MTU的回叫已更改。

Parameters
device BluetoothDevice: The remote device that requested the MTU change
mtu int: The new MTU size

onNotificationSent

Added in API level 21 
void onNotificationSent (BluetoothDevice device, 
                int status)

Parameters
device BluetoothDevice: The remote device the notification has been sent to
status int: GATT_SUCCESS if the operation was successful

onServiceAdded

Added in API level 18 
void onServiceAdded (int status, 
                BluetoothGattService service)

指示本地服务是否已成功添加。

Parameters
status int: Returns GATT_SUCCESS if the service was added successfully.
