Datasheet

For example, to insert the 'Flags' Data Type (Data Type Value 0x01), and set the value to

0x06/0b00000110 (BR/EDR Not Supported and LE General Discoverable Mode) we would

use the following byte array:

0x02 indicates the number of bytes in the entry

0x01 is the 'Data Type Value' and indicates that this is a 'Flag'

0x06 (0b00000110) is the Flag value, and asserts the following fields (see Core

Specification 4.0, Volume 3, Part C, 18.1):

LE General Discoverable Mode (i.e. anyone can discover this device)

BR/EDR Not Supported (i.e. this is a Bluetooth Low Energy only device)

If we also want to include two 16-bit service UUIDs in the advertising data (so that listening

devices know that we support these services) we could append the following data to the

byte array:

0x05 indicates that the number of bytes in the entry (5)

0x02 is the 'Data Type Value' and indicates that this is an 'Incomplete List of 16-bit

Service Class UUIDs'

0x0D 0x18 is the first 16-bit UUID (which translates to 0x180D, corresponding to the

Heart Rate Service).

0x0A 0x18 is another 16-bit UUID (which translates to 0x180A, corresponding to the

Device Information Service).

Codebase Revision: 0.3.0

Parameters: The raw byte array that should be inserted into the advertising data section of

02-01-06

05-02-0D-18-0A-18

Including the service UUIDs is important since some mobile applications will only

work with devices that advertise a specific service UUID in the advertising packet.

This is true for most apps from Nordic Semiconductors, for example.
