GATT#
Generic Attribute Profile (GATT) functions provide access to the BLE GATT protocol.
The response payload for all the aysnchronous APIs will be indicated to the application through the corresponding callback functions as described in the following sections. The response payload structure is described in the Callback Declarations section. This section provides a reference to GATT functions:
Synchronous Client functions to implement a synchronous Generic Attribute Profile (GATT) client.
Asynchronous Client functions to implement an asynchronous Generic Attribute Profile (GATT) client.
Server functions to implement a Generic Attribute Profile (GATT) server.
