12. Customizing the Proteus-III

12.1. DIS - Device information service

Besides the AMBER SPP-like profile for data transmission, the Proteus-III contains the so
called Device Information Service. This profile exposes manufacturer information about a
device and is used to personalize the Proteus-III to fuse with the custom product. The Device
Information Service is a standard Bluetooth

®

LE profile that is recognized by all devices with

Bluetooth

®

capabilities. It contains the following fields, that can only be modified by updating

the respective user setting using the

CMD_SET_REQ

command:

Field name

User setting

Maximum length

Manufacturer Name String

DIS_ManufacturerName

64

Model Number String

DIS_ModelNumber

64

Serial Number String

DIS_SerialNumber

64

Hardware Revision String

DIS_HWVersion

16

Software Revision String

DIS_SWVersion

16

Furthermore, the user setting

DIS_Flags

defines which of the described DIS fields are finally

placed in the DIS profile. Thus after adding content to the a DIS field user setting, like

DIS_ManufacturerName

, the user setting

DIS_Flags

has to be adapted such that the content

is added to the profile.

12.2. UUID

The UUID is a unique number identifying a Bluetooth

®

LE profile and thus describing its func-

tions. The Proteus-III using its standard UUID is compatible to all devices that implement the
AMBER SPP-like profile, whichever device it is integrated. To suspend this interoperability,
the user setting

RF_SPPBaseUUID

can be used to modify the UUID of the AMBER SPP-like

profile. With this, a new custom SPP-like profile is defined that is solely known to those that
chose the new UUID.
To generate a custom UUID the Bluetooth

®

SIG recommends to use the tool:

http://www.uuidgenerator.net/

12.3. Appearance

The appearance of the Bluetooth

®

device is a 2 Bytes value defined by the Bluetooth

®

SIG.

It can be configured by adapting the parameter

RF_Appearance

.
