public abstract class GattReadRequest

Object
GattReadRequest

A read request from a connected central, delivered to GattServerListener.characteristicReadRequest(GattReadRequest) or GattServerListener.descriptorReadRequest(GattReadRequest). Answer promptly with [#respond(byte[])] or reject(GattStatus) – centrals time out unanswered requests.

Constructors

Methods

`public` `BleCentral getCentral()`	The central issuing the request.
`public` `GattLocalCharacteristic getCharacteristic()`	The requested characteristic, or `null` for a descriptor read.
`public` `GattLocalDescriptor getDescriptor()`	The requested descriptor, or `null` for a characteristic read.
`public int getOffset()`	The read offset for long reads; `0` for plain reads.
`public abstract void respond(byte[] value)`	Sends the value to the central.
