Property: how the data should be handled by the client (Android App) e.g. read, write, write without response, notify, and indicate. Value: the actual value of the characteristic e.g. 1089

A GATT Server is a device which stores attribute data locally and provides data access methods to a remote GATT Client paired via BLE. A GATT Client is a device which accesses data on a remote GATT Server, paired via BLE, using read, write, notify, or indicate operations. Once two devices are paired each device can act as both a GATT Server and a GATT Client.

Android There are many resources available on Bluetooth on Android, but unfortunately many are incomplete snippets, use out-of-date concepts, or only explain half of the puzzle! In this series, we will learn how to set up both a Bluetooth Low Energy (BLE) Client and Server and demystify the Generic Attribute Profile (GATT) communication process.

. If the given value is too large according to the maximum BGAPI payload size, the system will select the maximum possible value as the maximum ATT_M Windows usually operates in the client role. Nevertheless, many scenarios arise which require Windows to act as a Bluetooth LE GATT Server as well.
