readValue()
Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.
The BluetoothGATTDescriptor.readValue()
method returns a Promise
that resolves to an ArrayBuffer
holding a duplicate of the value
property if it is available and supported. Otherwise it throws an error.
Syntax
JavaScript
Copy Code
BluetoothGATTDescriptor.readValue().then(function(value[]) { ... })

A Promise
that resolves to an ArrayBuffer
.
