Datasheet

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

0x02 is the 'Data Type Value (https://adafru.it/cYs)' 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 (https://adafru.it/ddB)).

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

Service (https://adafru.it/ecj)).

Codebase Revision: 0.3.0

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

being careful to stay within the space limits defined by the Bluetooth Core Specification.

Response: None

# Advertise as Discoverable and BLE only with 16-bit UUIDs 0x180D and 0x180A

AT+GAPSETADVDATA=02-01-06-05-02-0d-18-0a-18

The results of this command can be seen in the screenshot below, taken from a sniffer analyzing the advertising

packets in Wireshark. The advertising data payload is higlighted in blue in the raw byte array at the bottom of the

image, and the packet analysis is in the upper section:

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.
