2.1.1.6.1 Bluetooth® Class of Device (CoD)
The Class-of-Device (CoD) is a 24-bit field specifying the capabilities of a
Bluetooth
tion" (FHS) during the device search. According to the Bluetooth
the CoD describes the capabilities of the device, thus supporting the search for
devices with certain functionalities.
The CoD enables a rapid assignment of remote devices to different device
categories such as network, audio, telephony. It is divided into the Major Ser-
vice Class (bit 23...13), Major Device Class (bit 12...8) and Minor Device
Class (bit 7...2).
Internal device (sub)classes have been specified for the WAGO module. The
device class for the WAGO-I/O-SYSTEM 750 is represented by bit values 1,
1, 1, in bits 7, 6, 5. It is represented by the bit string 110 for bits 4, 3, 2 (see
Table 4).
