Bluetooth 4.0 Devices
Tstack provides early support for Bluetooth Smart devices, both as single mode or dual mode stack.
Bluetooth Smart devices implement one or more GATT profiles. These GATT profiles define a set of one or more Services. Each Service in turn defines a set of Characteristics. These profiles have a similar role as the SDP records in classic Bluetooth.In BTstack, a GATT profile compiler converts a textual representation of the GATT Services and Characteristics into a compact internal database used by the ATT protocol server.
The ATT protocol server answers incoming ATT requests based on information provided in the compiled database and provides read- and write-callbacks for dynamic attributes.
GATT Profiles GATT profiles are defined by a simple textual comma separated value (.csv) representation. While the description is easy to read and edit, it is compact and can be placed in ROM.
