Bluetooth® devices must comply with the Bluetooth specification and also be compatible with the subset of Bluetooth profiles necessary to use desired services. Bluetooth profiles reside on top of the Bluetooth core specification and optional additional protocols. The Assigned Numbers developer database lists assigned. Use Assigned Numbers in the Service Discovery Protocol (SDP) for searching for services, a browse group list, documentation URL, and an icon URL.. However, for new profiles, Service Class UUIDs shall not be used in a BluetoothProfileDescriptorList universal attribute and Profile UUIDs shall not be used in a. Generic Access Profile. Assigned numbers are used in GAP for inquiry response, EIR data type values, manufacturer-specific data, advertising data, low energy UUIDs and appearance characteristics, and class of device. purpose of defining multiple IACs is to limit the number of responses that are received when scanning devices within range. #..

Bluetooth Assigned Numbers are primarily of a 'public service' nature. The remaining 11 bits are used to indi- cate device type category and other device-specific characteristics. Any reserved but otherwise unassigned bits, such as in the Major Service. Class field, should be set to 0. Figure 1.2: The Class of. In the 'format #1' of the CoD (Format Type field = 00), 11 bits are assigned as a bit-mask (multiple bits can be set) each bit corresponding to a high level generic category of service class. Currently 7 categories are defined. These are primarily of a 'public service' nature. The remaining 11 bits are used to indicate device type. characteristics of any application based solely on the assignment of the Major or Minor device class. 1.2.1 Major Service Classes.

DeviceClass Description The DeviceClass class represents the CoD record as denned by the Bluetooth specification. This record is denned in the Bluetooth Assigned Numbers document and contains information on the type of the device and the type of services available on the device. This eliminates the overhead of performing a service search on a device that does not have the requested service.

Overview. BluetoothClassOfDevice is named after the Class of Device(CoD) field which is defined in Assign Numbers of Bluetooth Spec. Every single Bluetooth device should have its CoD and is able to be retrieved at discovering stage. The DeviceClass class represents the class of device (CoD) record as defined by the Bluetooth specification. This record is defined in the Bluetooth Assigned Numbers document and contains information on the type of the device and the type of services available on the device. The Bluetooth Assigned Numbers document. There are two places on a device where class code information can be placed.One place is in the Device Descriptor, and the other is in Interface Descriptors. Some defined class codes are allowed to be used only in a Device Descriptor, others can be used in both Device and Interface Descriptors, and. www.bluetooth.com. Assigned numbers for Baseband identifies the Inquiry Access codes and Class of Device/Service (CoD) fields. Currently our device reports are of class device 0x540, which is Peripheral – keyboard.

We may want to filter them out until Android provides a name for these devices as it should come later. I'm unable to reproduce this issue 100.

The CoD is divided into the major service class, the major device class, and the minor device class field. Two bits of the major service class field are reserved. The CoD can be assigned by the application; it is neither fixed by the hardware nor the. Bluetooth. The Bluetooth APIs let applications: Scan for other Bluetooth devices (including BLE devices). Query the local Bluetooth adapter for paired Bluetooth devices. Establish RFCOMM channels/sockets. Connect to specified sockets on other devices. Transfer data to and from other devices.

It characterizes devices according to their functionality, in order to allow a pre-selection of potential communication peers prior to connection establishment.

Bluetooth devices are assigned to one of three power classes: 1,. 2 and 3 (Table 1) and have correspondingly different transmission powers and transmission ranges.. small and cheap and use little power, a large number of devices are already equipped with them. Bluetooth enables data. Provides classes that manage Bluetooth functionality, such as scanning for devices, connecting with devices, and managing data transfer between devices. The Bluetooth API supports both "Classic Bluetooth" and Bluetooth Low Energy. For more information about Classic Bluetooth, see the Bluetooth guide. For more. Bluetooth Low Energy or Smart Bluetooth provides a new environment for devices with small amount of data to transfer and lower power consumption...
