=== readValue() ===
=== readValue() ===


; Description
; Description
: Read the characteristic value from the remote device. The cached value property will also be updated after retrieving the value.
: Read the characteristic value from either remote device (client role) or the local device (server role). In client mode, the cached value property will also be updated after retrieving the value from the remote GATT server.


; Return
; Return
: A Promise to indicate whether the operation is resolved or rejected. The Promise is resolved along with the value retrieved from the remote device.
: A Promise to indicate whether the operation is resolved or rejected. The Promise is resolved along with the value retrieved from the remote device or local device.


=== writeValue(ArrayBuffer value) ===
=== writeValue(ArrayBuffer value) ===


; Description
; Description
: Write the characteristic value to the remote device.
: Write the characteristic value to the GATT server. If the local device is the GATT client, the value will be written to the remote GATT server. On the other hand, if the local device is the GATT server, the value will be written to [[B2G/Bluetooth/WebBluetooth-v2/BluetoothGattCharacteristic#value|value]].


; Parameter
; Parameter
: ''value''
: ''value''
:: Desired value to be written to the remote device.
:: Desired value to be written to the GATT server.


; Return
; Return
: A Promise to indicate whether the operation is resolved or rejected. The Promise is resolved along with the characteristic value after this write operation.
: A Promise to indicate whether the operation is resolved or rejected.


=== startNotifications() ===

Line 194: Line 203:
; Return
; Return
: A Promise to indicate whether the operation is resolved or rejected. The Promise is rejected if there is no Client Characteristic Configuration descriptor (CCCD) for this characteristic.
: A Promise to indicate whether the operation is resolved or rejected. The Promise is rejected if there is no Client Characteristic Configuration descriptor (CCCD) for this characteristic.
=== addDescriptor(DOMString uuid, GattPermissions permissions, ArrayBuffer value) ===
; Description
: Adds a descriptor to this characteristic.
; Parameter
: ''uuid''
:: UUID of the descriptor to add.
: ''permissions''
:: [[B2G/Bluetooth/WebBluetooth-v2/BluetoothGattCharacteristic#GattPermissions|GattPermissions]] of the descriptor to add.
: ''value''
:: The initial value of this descriptor.
; Return
: A Promise to indicate whether the operation is resolved or rejected. If the Promise is resolved, it returns the added [[B2G/Bluetooth/WebBluetooth-v2/BluetoothGattDescriptor#BluetoothGattDescriptor|BluetoothGattDescriptor]] object, and property [[B2G/Bluetooth/WebBluetooth-v2/BluetoothGattCharacteristic#descriptors|descriptors]] is also updated with the added descriptor.
