I'm looking for a list of Bluetooth GATT Services with a short description of each. I' m developing a BLE Android App and have to choose the best service. Share.
GATT (General Agreement on Tariffs and Trade) som reglerar varuhandel mellan länder,; GATS (General Agreement on Trade in Services) som reglerar handel
Jetpack. Kotlin. A 16-bit Universally Unique Identifier (UUID) may be allocated by the SIG for use with a custom GATT-based service defined by the member. UUIDs are used in Bluetooth® protocols and applications. The SIG provides UUIDs for all the types, services, and profiles it defines.
GATT services group conceptually related attributes in one common section of the attribute information set in the GATT server. The specification refers to all the attributes within a single service as the service definition. The GATT defines the format of services and their characteristics, and the procedures that are used to interface with these attributes such as service discovery, characteristic reads, characteristic writes, notifications, and indications. GATT takes on the same roles as the Attribute Protocol (ATT). GATT is an acronym for the Generic Attribute Profile, and it defines the way that two Bluetooth Low Energy devices transfer data back and forth using concepts called Services and Characteristics. Primary services are the top level of the GATT tree.
SDP, 0x0001, See Bluetooth Service Discovery Protocol (SDP), Bluetooth SIG. RFCOMM, 0x0003, See RFCOMM with TS 07.10, Bluetooth SIG. TCS-BIN
GATT provides profile discovery and description services for the BLE protocol. It defines how ATT attributes are grouped together into sets to form services. The Bluetooth Special Interest Group has a standardized GATT (G eneritt ATT ribute Profile) for heart rate monitors called the Heart Rate profile.
Gatt Heating and Air Conditioning is St. Albert's premier heating and cooling company. Since 2006 Gatt Heating has been installing HVAC systems, replacing and upgrading furnaces, installing air conditioners and providing the highest level of 24/7 service.
The SIG provides UUIDs for all the types, services, and profiles it defines. The Generic Attributes (GATT) is the name of the interface used to connect to Bluetooth LE devices. The interface has one or more Bluetooth Services, identified by unique ids, that contain Bluetooth Characteristics also identified by ids.

UUIDs are used in Bluetooth® protocols and applications.
To expose data to another device, you must instantiate at least one service on your device. Adafruit's Bluefruit LE Pro modules support some 'standard' services, described below (more may be added in the future).

Over the years, Gatt Shipping has established an international set-up with correspondents in the major ports and cities worldwide, offering full load and groupage container shipments to their wide client base. I'm trying to get data from a custom GAP peripheral, GATT server.
You must declare the "bluetooth" capability in Package.appxmanifest. The first step to do this is to query for services: GattDeviceServicesResult result = await bluetoothLeDevice.GetGattServicesAsync(); if (result.Status == GattCommunicationStatus.Success) { var services = result.Services; // } Once the service of interest has been identified, the next step is to query for characteristics. To use an already implemented GATT Service, you only have to add it to your application's GATT file with: #import
