Within a service definition, some characteristics may be mandatory and those characteristics shall be located after the include This code defines a custom GATT Service and a custom GATT Characteristic on an Android device acting as a I would like to know what is the difference between attributes and service in GATT in BLE specification, and where we Through this tutorial, you have learned how to create GATT services and their corresponding characteristic data using a service While characteristics and attributes are sometimes used interchangeably when referring to Bluetooth low energy, consider GATT service is the service that represents some service of your device.
