B2G/Bluetooth/WebBluetooth-v2/BluetoothClassOfDevice

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.

• BluetoothClassOfDevice.majorDeviceClass
• BluetoothClassOfDevice.minorDeviceClass

majorServiceClass

Description

majorServiceClass represents the Major Service Class of the CoD field of a Bluetooth Device. majorServiceClass "defines the general families of devices with which Bluetooth SIG members want their applications to be associated" [1].

Value type

unsigned short

Default value

LIMITED_DISCOVERABILITY(0x0001)

majorDeviceClass

Description

majorDeviceClass represents the Major Device Class of the CoD field of a Bluetooth Device. majorDeviceClass "is the highest level of granularity for defining a Bluetooth device" [1].

Value type

octet

Default value

UNCATEGORIZED(0x1F)

minorDeviceClass

Description

minorDeviceClass represents the Minor Device Class of the CoD field of a Bluetooth Device. minorDeviceClass "is interpreted only in the context of the Major Device Class (but independently of the Service Class field)" [1].

Value type

octet

Default value

0x00
