Gatt server vs client

The BLE ABS interface for the Bluetooth Low Energy Abstraction (BLE ABS) peripheral provides Bluetooth Low Energy Abstraction functionality. 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.

In computing terminology, both “client” and “server” refer to computers that are used for different purposes. A client is a small computer that accesses a server through a network. For example, in an organization, an employee logs in to the client machine to access the files and applications running on a server machine. gatt.Device is the base class for your Bluetooth device. You will need to subclass it to implement the Bluetooth GATT profile of your choice. Override gatt.Device.services_resolved() to interact with the GATT profile, i.e. start reading from and writing to characteristics or subscribe to characteristic value change notifications.

Even though it is most common for a Peripheral to be a Server and a Central to be a Client, it is perfectly possible to have a Peripheral that is only a Client, or a Central that is both a Server and a Client. 2021-3-9 · The sample app can act as a gatt client or server.

Here is a basic summary of each kind of functionality: GATT client - a device which accesses data on the remote GATT server via read, write, notify, or indicate operations. GATT server - a device which stores data locally and provides data access methods to a remote GATT client. The peripheral is known as the GATT Server, which holds the ATT lookup data and service and characteristic definitions, and the GATT Client (the phone/tablet), which sends requests to this server. All transactions are started by the main device, the GATT Client, which receives response from the secondary device, the GATT Server.

Indicate 2017-9-27 · Other GATT sub-procedures may be used if supported by both client and server. Specifics of each service are explained below.
