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 BluetoothRemoteGATTDescriptor.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

BluetoothRemoteGATTDescriptor.readValue().then(function(value[]) { ... })

Returns

Promise that resolves to an ArrayBuffer.
