The Generic Attribute layer is a layer of the Bluetooth protocol stack which manages the data transmitted through the Attribute protocol. It is responsible for establishing operations and framework for attribute data, which is the primary type of data sent and received in Bluetooth Low Energy communication.
The GATT layer is also the layer through which Bluetooth Smart (single-mode) devices may enjoy mediated communication with each other. Typically, single-mode devices are only able to maintain one connection at a time, and usually to the device occupying the Central role. However, in a GATT connection with the Central device, the Smart devices may communicate to each other through the Central device by acting simultaneously as GATT clients and GATT servers.
Global settings include radio and security settings for profiles and settings that apply to SCU. An administrator can define and change most global settings on the SCU Global window.
When you change global settings and tap Commit, the changes generally take effect immediately. To cause global settings changes to take effect without a power cycle, Summit software may have to reset and re-establish the WLAN connection between the Summit radio and the access point.
The following Global settings are configurable from the Global tab of the Summit Client Utility:
General Purpose Input/Output. A factory standard generic pin. By default it has no purpose, allowing for assignment later should a spare pin be needed. This saves on having to rearrange pins and insert a new one.
Graphical User Interface.
