BluetoothRemoteGATTCharacteristic: writeValue() method

Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

Use BluetoothRemoteGATTCharacteristic.writeValueWithResponse() and BluetoothRemoteGATTCharacteristic.writeValueWithoutResponse() instead.

The BluetoothRemoteGATTCharacteristic.writeValue() method sets a BluetoothRemoteGATTCharacteristic object's value property to the bytes contained in a given ArrayBuffer, calls WriteCharacteristicValue(this=this, value=value, response="optional"), and returns the resulting Promise.
